If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnity may be sought pursuant to either of the first or third paragraphs of this Section 8, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Person”) in writing, and the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding and all such fees and expenses shall be reimbursed as they are incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person, or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons. Any such separate firm for the Underwriters, each affiliate of any Underwriter and such control persons of Underwriters shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers who sign or signed the Canadian Prospectus or the Registration Statement and such control persons of the Company or authorized representatives shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel for which the Indemnified Person is entitled to be reimbursed in accordance with this paragraph, the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request, and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement: (i) includes an unconditional release of such Indemnified Person from all liability on claims that are the

subject matter of such proceeding; and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party.

If the indemnification provided for in the first and third paragraphs of this Section 8 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Securities (before deducting expenses) received by the Company and the aggregate fee payable by the Company to the Underwriters bear to the aggregate public offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, in no event shall an Underwriter be required to contribute any amount in excess of such aggregate fee or any portion of such fee actually received. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 8 are several in the percentages set forth opposite their names in Schedule II hereto, and not joint.

The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its officers or directors or any other person controlling the Company, and (iii) acceptance of and payment for any of the Securities.

9 Notwithstanding anything herein contained, any Underwriter (each, a “Terminating Underwriter”) may, in its absolute discretion, terminate its obligations under this Agreement, by notice given to the Company and the Representatives (or, if the Terminating Underwriter is a Representative, to the Company and the other Representatives), if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, either of the New York Stock Exchange or the Toronto Stock Exchange, (ii) trading of any securities of or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities or in Canada by the Canadian federal or provincial authorities or there shall have occurred a material disruption in commercial banking or securities settlement or clearance services, in Canada or the United States, (iv) there shall have occurred, developed or come into effect any event, action, state, condition, or major financial occurrence of national or international consequence or any law or regulation, any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the judgment of that Terminating Underwriter is material and adverse to the financial markets in Canada or the United States, or (v) there shall have occurred a Material Adverse Effect, and (b) in the case of events specified in clauses (a)(i) through (v) above, the occurrence of such event makes it, in the judgment of that Terminating Underwriter, impracticable or inadvisable to market the Securities on the terms and in the manner contemplated in the Time of Sale Information and the Prospectuses, or to enforce contracts for the sale of the Securities.

The rights of termination contained in this Section 9 may be exercised by any of the Underwriters and are in addition to any other rights or remedies any of the Underwriters may have in respect of any default, act or failure to act or non-compliance by the Company in respect of any of the matters contemplated by this Agreement or otherwise. In the event of any such termination, there shall be no further liability on the part of the Terminating Underwriter to the Company or on the part of the Company to the Terminating Underwriter except in respect of any liability which may have arisen prior to or arise after such termination under Sections 8 and 10 (and, for clarity, the Terminating Underwriter will not be entitled to any portion of the fee payable by the Company pursuant to Section 3). A notice of termination given by an Underwriter under this Section 9 shall not be binding upon any other Underwriter.

Upon the delivery of a notice of termination by a Representative under this Section 9, the Company may, in its absolute discretion, proceed with the sale of Securities in

accordance with the terms of this Agreement with the remaining Underwriters or terminate this Agreement.

10 If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company agrees to reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and expenses of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering of Securities. The Underwriters or such Underwriters as have so terminated this Agreement will provide the Company with invoices in respect of any such out-of-pocket expenses to be reimbursed.

11 If one or more of the Underwriters shall fail at the Closing Date to purchase the aggregate principal amount of Securities which it or they are obligated to purchase under this Agreement or shall have exercised its right to terminate this Agreement as provided in Section 9 (the “Unpurchased Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting and non-terminating Underwriters, or any other underwriters, to purchase all, but not less than all, of the Unpurchased Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24 hour period, then: (a) if the aggregate principal amount of Unpurchased Securities does not exceed 10% of the aggregate principal amount of Securities, each of the non-defaulting and non-terminating Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Unpurchased Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting and non-terminating Underwriters; or (ii) if the number of Unpurchased Securities exceeds 10% of the aggregate principal amount of Securities, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter. No action taken pursuant to this Section 11 shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, the Representatives shall have the right to postpone the Closing Date for a period not exceeding five days in order to effect any required changes in the Registration Statement, the Time of Sale Information or Prospectuses or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 11.

12 This Agreement shall enure to the benefit of and be binding upon the Company, and each Underwriter, and to the extent provided for in Section 8, each person referred to in such section, and in each case, their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

13 The Representatives are hereby authorized by each of the other Underwriters to act on its behalf and the Company shall be entitled to and shall act on any notice given in accordance with this Section 13 or agreement entered into by or on behalf of the Underwriters by the Representatives which represents and warrants that it has irrevocable authority to bind the Underwriters, except in respect of any consent to a settlement pursuant to Section 8, which consent shall be given by the Indemnified Party, or a notice of termination pursuant to Section 9, which notice may be given by any of the Underwriters. The Representatives shall consult with the other Underwriters concerning any matter in respect of which they act as representative of the Underwriters. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given on their behalf to the Representatives at: ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated, ▇▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇-▇▇▇-▇▇-▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: High Grade Transaction Management/Legal (fax no.

14 This Agreement may be executed in counterparts and delivered by facsimile or other electronically transmitted format, each of which shall be deemed to be an original and all of which together shall constitute one and the same instrument.

15 THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

16 The Company acknowledges that in connection with the offering of the Securities: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement, and (iii) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

17 The Company hereby submits to the non-exclusive jurisdiction of any U.S. federal or state court located in the Borough of Manhattan, the City and County of New York in any

action, suit or proceeding arising out of or relating to or based upon this Agreement or any of the transactions contemplated hereby, and the Company irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding in any such court arising out of or relating to this Agreement or the transactions contemplated hereby and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding has been brought in an inconvenient forum. The Company irrevocably appoints CT Corporation System as its authorized agent in the Borough of Manhattan, the City and County of New York upon which process may be served in any such action, suit or proceeding and agrees that service of process upon such agent at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇, ▇▇▇▇▇, ▇▇▇, and written notice of said service to the Company by the person serving the same to the Company’s address as provided in this Agreement, shall be deemed in every respect effective service of process upon the Company in any such action, suit or proceeding, and the Company further agrees to take any and all such action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of ten years from the date of this Agreement.

18 With respect to any action, suit or proceeding arising out of or relating to or based upon this Agreement or any of the transactions contemplated hereby, the Company irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled, and with respect to any such action, suit or proceeding, the Company waives any such immunity in any court of competent jurisdiction, and the Company will not raise or claim or cause to be pleaded any such immunity at or in respect of any such action, suit or proceeding, including, without limitation, any immunity pursuant to the U.S. Foreign Sovereign Immunities Act of 1976, as amended.

The obligation of the Company in respect of any sum due to any Underwriter under this Agreement shall, notwithstanding any judgment in a currency other than U.S. dollars or any other applicable currency (the “Judgment Currency”), not be discharged until the first business day following receipt by such Underwriter of any sum adjudged to be so due in the Judgment Currency on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase U.S. dollars or any other applicable currency with the Judgment Currency; if the U.S. dollars or other applicable currency so purchased are less than the sum originally due to such Underwriter hereunder, the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss in respect of any sum due to such Underwriter from the Company. If the U.S. dollars or other applicable currency so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company an amount equal to the excess of the U.S. dollars or other applicable currency so purchased over the sum originally due to such Underwriter hereunder.

Very truly yours,

16 No stamp duty, registration or documentary taxes, duties or similar charges are payable under the laws of the Province of Ontario or the federal laws of Canada in connection with the creation, issuance, sale and delivery of the Securities or the authorization, execution, delivery and performance of the Underwriting Agreement and the Indenture.

18 No withholding tax imposed under the federal laws of Canada or the laws of the Province of Ontario will be payable in respect of the payment of any fee as contemplated by the Underwriting Agreement to an Underwriter that is not resident in Canada or is deemed not to be resident in Canada

under the Income Tax Act (Canada) (a Non-Resident Underwriter), provided that such Non-Resident Underwriter deals at arm’s length with the Company, that any such fee is payable in respect of services rendered by or on behalf of such Non-Resident Underwriter wholly outside of Canada that are performed by such Non-Resident Underwriter in the ordinary course of business carried on by it that includes the performance of such services for a fee, and that any such amount is reasonable in the circumstances.

19 No withholding tax imposed under the federal laws of Canada or the laws of the Province of British Columbia will be payable in respect of the payment of any fee as contemplated by the Underwriting Agreement to an Underwriter that is not resident in Canada or is deemed not to be resident in Canada under the Income Tax Act (Canada) (a Non-Resident Underwriter), provided that such Non-Resident Underwriter deals at arm’s length with the Company, that any such fee is payable in respect of services rendered by or on behalf of such Non-Resident Underwriter wholly outside of Canada that are performed by such Non-Resident Underwriter in the ordinary course of business carried on by it that includes the performance of such services for a fee, and that any such amount is reasonable in the circumstances.

20 No goods and services tax or harmonized sales tax imposed under the federal laws of Canada will be collectible by a Non-Resident Underwriter in respect of the payment of any fee to such Non-Resident Underwriter as contemplated by the Underwriting Agreement, provided that such fee is payable as consideration for the supply of services performed by such Non-Resident Underwriter wholly outside of Canada.

21 In a proceeding brought before a court of competent jurisdiction in the Province of Ontario or British Columbia (an Ontario or British Columbia Court) for the enforcement of the Underwriting Agreement, the Base Indenture, the Fourth Supplemental Indenture and the Securities (the Foreign Agreements), the Ontario or British Columbia Court would apply the law of the State of New York (New York Law), in accordance with the parties’ choice of New York Law in such Foreign Agreements, to all issues which, under the applicable laws of the Province of Ontario or British Columbia (Ontario or British Columbia Law), are to be determined in accordance with the chosen law of the contract, provided that: (i) the parties’ choice of New York Law is bona fide and legal and there is no reason for avoiding such choice of law on the grounds of Ontario or British Columbia public policy as such term is interpreted under Ontario or British Columbia Law (Public Policy); (ii) in any such proceeding, and notwithstanding the parties’ choice of New York Law, the Ontario or British Columbia Court (a) will not take judicial notice of the provisions of New York Law but will only apply such provisions if they are pleaded and proven by expert testimony; (b) will not apply New York Law and will apply Ontario or British Columbia Law, as applicable, to matters which would be characterized under Ontario or British Columbia Law, as procedural; (c) will apply provisions of Ontario or British Columbia Law that have overriding effect; (d) will not apply New York Law if such application would be characterized under Ontario or British Columbia Law as the direct or indirect enforcement of a foreign revenue, expropriatory or penal or other public law or if its application would be contrary to Public Policy; and (e) will not enforce the performance of any obligation that is illegal under the laws of any jurisdiction in which the obligation is to be performed. We have no reason to believe that the choice of New York Law in this context would be contrary to Public Policy.

22 An Ontario or British Columbia Court would give a judgment based upon a final and conclusive in personam judgment of a court exercising jurisdiction in the State of New York (the Foreign Court) for a sum certain, obtained against the Company with respect to a claim arising out of a Foreign Agreement (a Foreign Judgment), without reconsideration of the merits provided that:

(a) the Foreign Court had jurisdiction over the subject matter and the parties to the Foreign Agreements are recognized by the Ontario or British Columbia Court, as applicable, and the Foreign Court;

(b) no new admissible evidence, right or defence relevant to the action accrues or is discovered prior to the rendering of a judgment by the Ontario or British Columbia Court;

(c) an action to enforce the Foreign Judgment is commenced in the Ontario or British Columbia Court within any applicable limitation period;

(d) the Ontario or British Columbia Court has discretion to stay or decline to hear an action on the Foreign Judgment if the Foreign Judgment is under appeal, or there is another subsisting judgment in any jurisdiction relating to the same cause of action; and

(e) the Ontario or British Columbia Court will render judgment only in Canadian dollars,

subject to the following defences:

(i) the Foreign Judgment was obtained by fraud or in a manner contrary to the principles of natural justice;

(ii) the Foreign Judgment is for a claim which under Ontario or British Columbia Law would be characterized as based on a foreign revenue, expropriatory or penal or other public law;

(iii) the Foreign Judgment is contrary to Public Policy or to an order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the Competition Act (Canada) in respect of certain judgments referred to therein; or

(iv) the Foreign Judgment has been satisfied or is void under Foreign Law.

The submission to the non-exclusive jurisdiction of the Foreign Court and the appointment of CT Corporation System as agent to receive service of process pursuant to the provisions of the Foreign Agreements would be recognized by an Ontario or British Columbia Court as conferring jurisdiction on the Foreign Court.

FORM OF NEGATIVE ASSURANCE LETTER OF

NORTON ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ CANADA LLP

We have participated in conferences with officers and other representatives of the Company, representatives of the Company’s auditors and of the Underwriters, representatives of the Company’s U.S. counsel and representatives of the Underwriters’ Canadian and U.S. counsel, at which the contents of the Registration Statement, the Time of Sale Information or the U.S. Prospectus and related matters were discussed. Although we did not participate in the preparation of the documents and information incorporated by reference in the U.S. Prospectus, we have reviewed such documents and information.

We have not made any independent investigation or verification of and are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in or incorporated by reference in the Registration Statement, the Time of Sale Information or the U.S. Prospectus (other than such conclusions of law as to which an opinion has been separately delivered to you). As the determination of materiality or whether a fact is a material fact under the Securities Act (Ontario) is a factual and not a legal matter requiring expertise on the effect which information would have on market prices or values of securities of the Company, we have accordingly relied as to materiality, to a large extent, on the opinions of officers and other representatives of the Company.

On the basis of the information which we gained in the course of the performance of our role as Canadian counsel to the Company in respect of the offering of the Securities, no facts have come to our attention in the course of our review and discussions in connection with the offering of the Securities that have caused us to believe that: (i) at the time it became effective, the Registration Statement; (ii) as of the Applicable Time, the Time of Sale Information; or (iii) at the time the U.S. Prospectus was issued, or at the Closing Date, the U.S. Prospectus (in each case excluding the financial statements and other financial and statistical information included or incorporated by reference therein or derived therefrom, the reports of management’s assessment of the effectiveness of internal controls over financial reporting and the auditors’ report on the effectiveness of the Company’s internal controls over financial reporting, on which we do not comment), contained or contains any untrue statement of a material fact within the meaning of the Securities Act (Ontario) or omitted or omits to state a material fact that is required to be stated or that is necessary to make a statement therein not misleading in the light of the circumstances in which it was made, within the meaning of the Securities Act (Ontario).

As used herein, (i) “Applicable Time” means 3:45 p.m. (Eastern Time) on June 7, 2018 and (ii) “Time of Sale Information” means the U.S. Final Prospectus, as supplemented by the U.S. Preliminary Supplement and the Final Term Sheet.

Ladies and Gentlemen:

We have acted as United States counsel to TELUS Corporation, a corporation organized under the laws of British Columbia (the “Company”), in connection with the Underwriting Agreement (the “Underwriting Agreement”), dated June 7, 2018, among you and the Company, relating to the offering and sale of U.S.$750,000,000 aggregate principal amount of 4.600% Notes due November 16, 2048 (the “Notes”) of the Company. This opinion is being furnished at the request of the Company as contemplated by Section 7(g) of the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form F-10 (File No. 333—224895) under the Securities Act of 1933, as amended (the “Act”). The Registration Statement was filed on May 14, 2018, was amended on May 18, 2018 and became effective upon filing on May 18, 2018 pursuant to Rule 467(a) under the Act. In this opinion, the Registration Statement at the time it became effective under the Act, including the documents incorporated by reference therein, is referred to as the “Registration Statement”; the base prospectus, dated May 17, 2018, included in the Registration Statement (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement, dated June 7, 2018, as filed pursuant to General Instruction II.L. of Form F-10, including the documents incorporated by reference therein, immediately prior to the Time of Sale is referred to as the “U.S. Pricing Prospectus”; the U.S. Pricing Prospectus, taken together with the documents set forth in Annex D to the Underwriting Agreement, dated June 7, 2018, is referred to as the “Pricing Disclosure Package”; and the Base Prospectus, as supplemented by the final prospectus supplement, dated June 7, 2018, as filed pursuant to General Instruction II.L. of Form F-10, including the documents incorporated by reference therein, is referred to as the “U.S. Prospectus.” Both the U.S. Pricing Prospectus and the U.S. Prospectus have been filed pursuant to General Instruction II.L. of Form F-10 in the manner and within the time period required by

said General Instruction II.L. The Company has filed a short form base shelf prospectus (the “Canadian Base Prospectus”), dated May 17, 2018, a preliminary prospectus supplement (together with the Canadian Base Prospectus and the documents incorporated by reference therein, the “Canadian Pricing Prospectus”), dated June 7, 2018, and a final prospectus supplement (together with the Canadian Base Prospectus and the documents incorporated by reference therein, the “Canadian Prospectus”), dated June 7, 2018, in each case, with the British Columbia Securities Commission.

The Commission’s website indicates that no stop order suspending the effectiveness of the Registration Statement has been issued.

In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents:

1. the Registration Statement;

2. the U.S. Pricing Prospectus;

3. the U.S. Prospectus;

4. the Underwriting Agreement;

5. the Indenture dated as of September 19, 2016 (the “Indenture”), among the Company, Computershare Trust Company, N.A., as U.S. trustee (the “U.S. Trustee”) and Computershare Trust Company of Canada, as Canadian trustee (the “Canadian Trustee”), as supplemented by the First Supplemental Indenture thereto dated September 19, 2016, as further supplemented by the Second Supplemental Indenture thereto dated March 6, 2017, the Third Supplemental Indenture thereto dated October 1, 2017 and the Fourth Supplemental Indenture thereto dated June 12, 2018 (the “Fourth Supplemental Indenture”) among the Company, the U.S. Trustee and the Canadian Trustee (including the covenants and conditions precedent to the authentication and delivery of the Notes and the execution and delivery of the Fourth Supplemental Indenture, and the related definitions);

6. the Notes; and

7. the Form F-X of the Company, dated May 11, 2018 (the “Form F-X of the Company”).

In addition, we have examined such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions and beliefs expressed below. We have also relied upon oral and written statements of officers and representatives of the Company, the factual matters contained in the representations and warranties made in the Underwriting Agreement and upon certificates of public officials and officers of the Company. The documents incorporated by reference into the Registration Statement and the U.S. Prospectus were prepared by the Company without our participation.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us

as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete.

We have also assumed, without independent investigation that (i) the Company is validly existing and in good standing under the laws of its jurisdiction of organization, (ii) the Company has all necessary corporate power to execute, deliver and perform its obligations under the Underwriting Agreement, the Indenture, the Fourth Supplemental Indenture and the Notes, (iii) the execution, delivery and performance of the Underwriting Agreement, the Indenture, the Fourth Supplemental Indenture and the Notes have been duly authorized by all necessary corporate action and do not violate the Articles of Incorporation or By-laws of the Company or the laws of its jurisdiction of organization and (iv) the due execution and delivery of the Underwriting Agreement, the Indenture, the Fourth Supplemental Indenture and the Notes under the laws of its jurisdiction of organization. We have also assumed that the Indenture and the Fourth Supplemental Indenture constitute the legal, valid and binding obligations of the U.S. Trustee and the Canadian Trustee and the due authentication of the Notes by the U.S. Trustee and the Canadian Trustee.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that:

1. The issuance and sale of the Notes by the Company, the execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Fourth Supplemental Indenture and the performance by the Company of its obligations thereunder will not violate those laws, rules and regulations of the United States of America and the State of New York (“Applicable Law”), in each case which in our experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement, the Indenture or the Fourth Supplemental Indenture or any judgment, order or decree of any New York or federal court or governmental authority binding upon the Company listed on Schedule I to this opinion. For purposes of this letter, the term “Applicable Law” does not include federal securities laws (except for purposes of the opinion expressed in paragraph 2 below) or state securities laws, anti-fraud laws, or any law, rule or regulation that is applicable to the Company, the Indenture, the Fourth Supplemental Indenture, the Notes, the Underwriting Agreement or the transactions contemplated thereby solely because such law, rule or regulation is part of a regulatory regime applicable to any party to the Underwriting Agreement or any of its affiliates due to the specific assets or business of such party or such affiliate.

2. No consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made, is required by the Company under any Applicable Law for the issuance and sale of the Notes by the Company, the execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Fourth Supplemental Indenture and the performance by the Company of its obligations thereunder. For purposes of this letter, the term “Governmental Authority” means any executive, legislative, judicial, administrative or regulatory body of the State of New York or the United States of America.

3. The Company is not and, after giving effect to the offering and sale of the Notes, and the application of their proceeds as described in the Pricing Disclosure Package and the U.S. Prospectus under the heading “Use of Proceeds,” will not be required to be, registered as an investment company under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission promulgated thereunder.

4. The statements in the Pricing Disclosure Package and the U.S. Prospectus under the heading “Certain United States Federal Income Tax Considerations,” to the extent that they constitute summaries of United States federal law or regulation or legal conclusions, have been reviewed by us and fairly summarize the matters described under that heading in all material respects.

5. The Registration Statement, the Form F-X of the Company, and the U.S. Prospectus, as of their respective effective or issue times, appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the rules and regulations of the Commission under the Act, except for the financial statements, financial statement schedules and other financial data included or incorporated by reference in or omitted from any of them, and the Form T-1, as to which we express no opinion. We have assumed, for purposes of this paragraph, (i) the compliance of the Canadian Prospectus with the requirements of British Columbia securities laws, as interpreted and applied by the British Columbia Securities Commission and (ii) that the exhibits to the Registration Statement and the documents incorporated by reference in the U.S. Prospectus include all reports or information that in accordance with the requirements of British Columbia securities laws, as interpreted and applied by the British Columbia Securities Commission, must be made publicly available in connection with the offering of the Notes. We understand that such matters are covered in the opinion of Norton ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Canada LLP furnished to you today.

6. The Indenture and the Fourth Supplemental Indenture have, to the extent execution and delivery are governed by the laws of the State of New York, been duly executed and delivered by the Company. The Indenture and the Fourth Supplemental Indenture constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except that the enforceability of the Indenture and the Fourth Supplemental Indenture may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally and possible judicial action giving effect to governmental actions relating to persons or transactions or foreign laws affecting creditors’ rights and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law); and the Indenture and the Fourth Supplemental Indenture conform in all material respects to the descriptions contained in the Pricing Disclosure Package and the U.S. Prospectus under the caption “Description of Debt Securities” and under the caption “Description of the Notes.” The Indenture has been duly qualified under the Trust Indenture Act.

7. The Notes have, to the extent execution is governed by the laws of the State of New York, been duly executed by the Company. The Notes, when duly issued and delivered by the Company against payment as provided in the Underwriting Agreement, will constitute the legal, valid and binding obligations of the Company entitled to the benefits of the Indenture and the Fourth Supplemental Indenture and enforceable against the Company in accordance with their

terms, except that the enforceability of the Notes may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally and possible judicial action giving effect to governmental actions relating to persons or transactions or foreign laws affecting creditors’ rights and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law); and the Notes, when issued and delivered, will conform in all material respects to the description contained in the Pricing Disclosure Package and the U.S. Prospectus under the caption “Description of Debt Securities” and under the caption “Description of the Notes”.

8. The Underwriting Agreement has, to the extent execution and delivery are governed by the laws of the State of New York, been duly executed and delivered by the Company.

9. Under the laws of the State of New York relating to the submission of personal jurisdiction, the Company has, pursuant to Section 17 of the Underwriting Agreement and Section 113 of the Indenture, validly and irrevocably (i) submitted to the non-exclusive jurisdiction of any federal or state court in the City, County and State of New York, in any action based on or under the Underwriting Agreement, the Indenture or the Fourth Supplemental Indenture or the transactions contemplated thereby, (ii) waived any objection to the venue of a proceeding in any such court and (iii) appointed CT Corporation System as its authorized agent for the purpose described in Section 17 of the Underwriting Agreement and Section 113 of the Indenture; and service of process effected on such agent in the manner set forth in Section 17 of the Underwriting Agreement and Section 113 of the Indenture will be effective to confer valid personal jurisdiction over the Company. This opinion is subject to the qualification that we express no opinion as to enforceability of forum selection clauses in the federal courts.

The opinions expressed above are limited to the laws of the State of New York and the federal laws of the United States of America. Our opinions are rendered only with respect to the laws, and the rules, regulations and orders under those laws, that are currently in effect. We express no opinion with respect to the enforceability of any indemnity against any loss in converting into a specified currency the proceeds or amount of a court judgment in another currency.

This letter is furnished by us solely for your benefit in connection with the transactions referred to in the Underwriting Agreement and may not be circulated to, or relied upon by, any other person without our prior written consent.

Ladies and Gentlemen:

We have acted as United States counsel to TELUS Corporation, a corporation organized under the laws of British Columbia (the “Company”), in connection with the Underwriting Agreement (the “Underwriting Agreement”), dated June 7, 2018, among you and the Company, relating to the offering and sale of U.S.$750,000,000 aggregate principal amount of 4.600% Notes due November 16, 2048 (the “Notes”) of the Company. This letter is being furnished at the request of the Company in connection with the delivery of our opinion to you of even date herewith (the “Opinion”) under the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form F-10 (File No. 333—224895) under the Securities Act of 1933, as amended (the “Act”). The Registration Statement was filed on May 14, 2018, was amended on May 18, 2018 and became effective upon filing on May 18, 2018 pursuant to Rule 467(a) under the Act. In this letter, the Registration Statement at the time it became effective under the Act, including the documents incorporated by reference therein, is referred to as the “Registration Statement”; the base prospectus, dated May 17, 2018, included in the Registration Statement (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement, dated June 7, 2018, as filed pursuant to General Instruction II.L. of Form F-10, including the documents incorporated by reference therein, immediately prior to the Time of Sale is referred to as the “U.S. Pricing Prospectus”; the U.S. Pricing Prospectus, taken together with the documents set forth in Annex D to the Underwriting Agreement, dated June 7, 2018, is referred to as the “Pricing Disclosure Package”; and the Base Prospectus, as supplemented by the final prospectus

supplement, dated June 7, 2018, as filed pursuant to General Instruction II.L. of Form F-10, including the documents incorporated by reference therein, is referred to as the “U.S. Prospectus.”

The primary purpose of our professional engagement was not to establish factual matters or financial, accounting or statistical information. In addition, many determinations involved in the preparation of the Registration Statement, the U.S. Pricing Prospectus and the U.S. Prospectus are of a wholly or partially non-legal character or relate to legal matters outside the scope of this letter. Furthermore, the limitations inherent in the independent verification of factual matters and in the role of outside counsel are such that we have not undertaken to independently verify, and cannot and do not assume responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the U.S. Pricing Prospectus or the U.S. Prospectus (other than as explicitly stated in paragraphs 4, 6 and 7 of the Opinion). The documents incorporated by reference into the Registration Statement and the U.S. Prospectus were prepared by the Company without our participation.

In the course of acting as United States counsel to the Company in connection with the offering of the Notes, we have participated in conferences and telephone conversations with officers and other representatives of the Company, its Canadian counsel, your representatives and your legal counsel and the independent registered public accountants for the Company during which conferences and conversations the contents of the Registration Statement, the Pricing Disclosure Package, the U.S. Prospectus and related matters were discussed. Based upon such participation (and relying as to factual matters on officers, employees and other representatives of the Company and its subsidiaries), our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder, we hereby advise you that our work in connection with this matter did not disclose any information that caused us to believe that (i) at the time it became effective, the Registration Statement (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference, as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) as of the Time of Sale, the Pricing Disclosure Package (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference, as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) at the time the U.S. Prospectus was issued, or at the Closing Date, the U.S. Prospectus (except for the financial statements, financial statement schedules and other financial data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference, as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.
