Exhibit 99.10

AMENDING AGREEMENT

TO ENCANA CORPORATION EMPLOYEE STOCK OPTION PLAN

RECITALS:

It was determined that Encana Corporation (“Encana”) reorganize the structure of Encana and its subsidiaries pursuant to a series of reorganization transactions, which included, among other things, (i) completing an arrangement (the “Arrangement”) under Section 192 of the Canada Business Corporations Act, pursuant to which, among other things, Encana completed a consolidation of the common shares of Encana (“Encana Common Shares”) on the basis of one post-consolidation share for each five pre-consolidation shares (the “Share Consolidation”), (ii) Ovintiv Inc. (the “Corporation”), a wholly-owned subsidiary of Encana, ultimately acquiring all of the issued and outstanding Encana Common Shares in exchange for shares of the Corporation on a one-for-one basis and becoming the parent company of Encana and its subsidiaries, and (iii) following the completion of the Arrangement, the Corporation migrating out of Canada and becoming a Delaware corporation (collectively, the “Reorganization”).

Prior to the Reorganization, Encana administered the “Encana Corporation Employee Stock Option Plan” (the “Stock Option Plan”), which was adopted with effect from October 1, 2001 and amended as of April 27, 2005, April 25, 2007, April 22, 2008, October 22, 2008, November 30, 2009, July 20, 2010, February 24, 2015 and February 22, 2016, pursuant to which a number of awards of stock options were made to Encana employees (the “Encana Options”).

As part of the Reorganization, and as of the Effective Date (as defined below), the Corporation assumed all of the outstanding Encana Options.

The Corporation wishes to continue the administration of a stock option plan for employees of the Corporation on substantially the same terms as set forth in the Stock Option Plan and the Grant Agreements (as defined below), and hereby adopts the Stock Option Plan in its entirety, subject to certain modifications.

To clarify and confirm the above, the Corporation wishes to amend the Stock Option Plan and the Grant Agreements as more particularly set forth in this Agreement.

Capitalized terms used herein and not otherwise defined have the meanings ascribed thereto in the Stock Option Plan.
