Eric Duncan

Eric Dawson Duncan (born 10 November 1987) is a Canadian politician who was elected to represent the riding of Stormont—Dundas—South Glengarry in the House of Commons of Canada in the 2019 Canadian federal election. He is a member of the Conservative Party of Canada. Prior to his election to Parliament, Duncan served as mayor of the township of North Dundas from 2010 to 2018. He is the first openly gay Conservative MP to serve in the House of Commons. He was appointed as Shadow Minister for Foreign Affairs in June 2026.

During his term as mayor he came out as gay, and during the 2019 federal election campaign he defended party leader Andrew Scheer over his stance on same-sex marriage by arguing that he would not run as a Conservative if his sexual orientation was not welcomed in the Conservative Party. After the Conservatives increased their seat count but did not displace the governing Liberals as the largest party in the House, Duncan argued that the party should rethink its approach to LGBTQ issues in order to resonate with voters.

In the 44th Parliament, Duncan introduced Private Member's Bill C-396, Stopping the Tax on the Carbon Tax Act, which sought to eliminate the goods and services tax from carbon pollution pricing. The bill did not pass the first reading. Duncan also jointly seconded C-377, An Act to amend the Parliament of Canada Act (need to know) C-358, An Act to amend the Excise Tax Act (carbon pollution pricing) and C-233, An Act to amend the Criminal Code and the Judges Act (violence against an intimate partner).

Duncan attended North Dundas District High School in Chesterville, Ontario.

At the time of the 2025 Canadian federal election, he lived in Cornwall, Ontario.
