Re: Nutrien Ltd. (the “Company”)

We refer to the short form base shelf prospectus of the above Company dated March 11, 2022 relating to the offer and issue from time to time, of up to U.S. $5,000,000,000 (or the equivalent in other currencies) of common shares, preferred shares, subscription receipts, debt securities, share purchase contracts and/or units of the Company (the “Prospectus”).

We, KPMG LLP, consent to being named and to the use, through incorporation by reference in the above mentioned Prospectus of our report dated February 16, 2023 to the shareholders and Board of Directors of the Company on the following consolidated financial statements:

Consolidated balance sheets as of December 31, 2022 and 2021,

the related consolidated statements of earnings, comprehensive income, cash flows, and changes in shareholders’ equity for the years then ended, and

the related notes.

KPMG LLP, an Ontario limited liability partnership and member firm of the KPMG global

organization of independent member firms affiliated with KPMG International Limited, a private

English company limited by guarantee. KPMG Canada provides services to KPMG LLP.

We report that we have read the Prospectus and all information therein and have no reason to believe that there are any misrepresentations in the information contained therein that are derived from the consolidated financial statements upon which we have reported or that are within our knowledge as a result of our audit of such consolidated financial statements. We have complied with Canadian generally accepted standards for an auditor’s consent to the use of a report of the auditor included in an offering document, which does not constitute an audit or review of the Prospectus as these terms are described in the CPA Canada Handbook – Assurance.

Yours very truly,
