The 2026 Ontario Premier League season is the eleventh season of the Ontario Premier League (and the first since rebranding from League1 Ontario), a Division 3 women's soccer league in the Canadian soccer league system and the highest level of soccer based in the Canadian province of Ontario. The league is split into three divisions with promotion and relegation between them.
The OPL1 and the OPL2 divisions will both be composed of 10 clubs, most returning from last season, with the exception of International FC that has replaced Alliance United FC in the top division. The OPL3 will be made up by three conferences containing total of 25 teams. These will be mostly reserve teams with some "A" teams and two newly licensed clubs.
Ontario Premier League 1 will be composed of 10 teams. Scrosoppi FC was promoted from the Championship division last season. Alliance United FC was relegated and subsequently left the league.
The 10 teams will face each other twice, once at home and once away for a total of 18 matches. At the end of the season, the club at the top of the standings will be crowned as Ontario Premier League champions. The club that finishes in 9th will advance to the promotion playoffs against the second-place finisher in the OPL2, while the 10th placed club will be automatically relegated to the OPL2 division.

A playoff will be played between the 9th placed team in the OPL1 and the 2nd placed team in the OPL2 in a single game for a place in the top tier in 2027.
Ontario Premier League 2 is composed of 10 teams, eight of those returning from the 2026 season. Alliance United FC was initially relegated from the Premier division, but withdrew from the league and sold their license to International FC who replace them in the division. Cambridge United joined after being promoted from the League2 division.
The first place team in the standings will be automatically promoted to the OPL1 for 2027, while the second-place finisher will advance to the promotion playoffs against the 9th-place finisher in the OPL1. The last place team will be relegated to the OPL3 for 2027.

Ontario Premier League 3 clubs will be divided in three regional conferences (unlike previous seasons which consisted of two conferences). Those clubs will be "A" teams that have not earned promotion to higher division, the "B" teams of OPL1 and OPL2 clubs, or newly licensed clubs. Kingston Sentinels and Richmond Hill SC join as expansion teams.
The winner of each division, as well as the best second-place finisher will advance to the OPL3 Playoffs. The winner of the playoffs will earn promotion to the OPL2 division. If the winner of the playoffs is a B team, they may decline promotion, and instead the top two A teams with the most regular-season points in the division will meet in a playoff to earn promotion.
