The 2020 Men's League1 Ontario season would have been the seventh season of play for League1 Ontario (L1O), a Division 3 men's soccer league in the Canadian soccer pyramid and the highest level of soccer based in the Canadian province of Ontario. For the first time this year, the league's entry in the 2021 Canadian Championship, the top national tournament for men's soccer teams, was to be determined by a "Champions Final", to be played between the regular season champions and the playoff champions.
