2020 Ontario Tankard

The 2020 Ontario Tankard, the provincial men's curling championship for Southern Ontario, was held from January 28 to February 2 at the Ed Lumley Arena in Cornwall, Ontario. The winning John Epping rink represented Ontario at the 2020 Tim Hortons Brier in Kingston, Ontario. The event was held in conjunction with the 2020 Ontario Scotties Tournament of Hearts, the women's provincial championship.

John Epping won his second Ontario Tankard by defeating Glenn Howard 8–3 in the final.

Qualification process
Nine teams qualified from two cash spiels (two each), an open qualifier (two teams), plus the top two southern Ontario teams in the CTRS standings (as of December 1, 2019). Originally the event was to have just eight teams, but CurlON decided on December 9, 2019 to expand the field to nine teams with the addition of one team qualifying through their CTRS ranking. This is a reduction from the ten teams which played in the 2019 Tankard, making the number of entries equal to the provincial Scotties.
