The 2025 Women's League1 Ontario season is the tenth of 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 Premier division is composed by 10 clubs, the Championship division by 9 clubs, all returning from last season. The League2 Ontario is made up by two conferences containing reserve teams and newly licensed clubs.
League1 Ontario Premier will be composed by 10 teams. NDC Ontario are the defending champions and Waterloo United (re-branded from BVB IA Waterloo) is new to the division after earning promotion from the Championship Division.
The 10 teams will face each other twice, once at home and once away and the club at the top of the standings will be crowned as League1 Ontario champions and gain a berth for the League1 Canada Interprovincial championship. The last placed team will be automatically relegated, while the 9th placed club will play a playoff game against the 2nd placed club of the Championship to stay in the league.

League2 Ontario clubs will be divided in regional conferences. Those clubs will be either the "B" team of Premier and Championship clubs or newly licensed clubs. Sudbury Cyclones, Railway City FC and Cambridge United joined as new clubs.
All teams will face each other team in their conference twice, once at home and once away. The top two teams in each division will advance to the promotion playoffs, with the winner being promoted to the Championship. 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.
