2023 Ontario Tankard

The 2023 Ontario Tankard, (known as the Port Elgin Chrysler 2023 Ontario Tankard Presented by Bruce Power for sponsorship reasons), the provincial men's curling championship for Southern Ontario, was held from January 24 to 29 at The Plex in Port Elgin, Ontario. The winning Mike McEwen rink represented Ontario at the 2023 Tim Hortons Brier on home soil in London, Ontario where they finished fourth place losing in the 3 vs. 4 Page Playoff game to Wild Card #1 6–3.

It was the second straight year that the event was held in Port Elgin. The 2022 event had been subject to COVID-19 restrictions, capping attendance at 500 people per draw, so the organizers requested that CurlON hold the event in Port Elgin again. The event was held in conjunction with the 2023 Ontario Scotties Tournament of Hearts, the provincial women's curling championship, which were held in Thornhill in 2022 (both events are held together in non-Olympic years).
