The Ontario Premier League (formerly known as League1 Ontario) is a semi-professional men's soccer league in Ontario, Canada. The league is sanctioned by the Canadian Soccer Association and the Ontario Soccer Association.
The Ontario Premier League consists of three tiers, with promotion and relegation between them. The top-two tiers consist of 12 teams each, while the lowest tier is uncapped in size.
In the Canadian soccer league system, the men's division is behind the fully-professional Canadian Premier League. It is part of Premier Soccer Leagues Canada (formerly League1 Canada), the national third tier with regional divisions, along with four other provincial leagues including the British Columbia Premier League, Alberta Premier League, Prairies Premier League, and Ligue1 Québec. The league champion qualifies for the Canadian Championship, Canada's domestic cup tournament. Dino Rossi serves as the commissioner of the league.
