The 2025 Men's League1 Ontario season is the eleventh of League1 Ontario, 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. The league is split into three divisions with promotion and relegation between them.
The Premier division will be composed of 11 clubs, the Championship division of 12 clubs, all returning from last season. The League2 Ontario will be made up by three conferences containing reserve teams and newly licensed clubs.
League1 Ontario Premier will be composed of 11 teams. FC London and St. Catharines Roma Wolves were promoted from the Championship division last season. ProStars FC dropped out of the league shortly prior to the release of the schedules and were not replaced. Blue Devils FC have re-branded as Oakville SC following a merger.
The 11 teams will face each other twice, once at home and once away for a total of 20 matches. At the end of the season, the club at the top of the standings will be crowned as League1 Ontario champions and gain a berth for the 2026 Canadian Championship. The club that finishes in 10th will advance to the promotion playoffs against the third place finisher in the Championship, while the 11th placed club will be automatically relegated to the Championship division.

League2 Ontario clubs will be divided in three regional conferences. Those clubs will be either the "B" team of Premier and Championship clubs or newly licensed clubs. Railway City FC and Cambridge United join as expansion teams.
The winner of each division, as well as the best second place finisher will advance to the League2 Playoffs. The winner of the playoffs will earn promotion to the Championship 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.

However, Rush Canada SA declined and forfeited the match.
