Five local member minor hockey associations have been selected as the hosts for the 2025 Ontario Hockey Federation (OHF) Championships.

The OHF Championships are a three day event that produces champions at the U13 (AA, A), U15 (AA, A) and U18 (AA, A) divisions. Other divisions and Hockey Canada Branches may participate as approved by the OHF Board of Directors. The All-Ontario Championships are the pinnacle events for U13 and U15 AAA hockey teams.

The OHF Championships will take place on the weekend of April 18-20, 2025 while the All-Ontario U13 and U15 AAAs take place April 9-13, 2025. The Central Region U18 AAA will be on March 31-April 6, 2025. Five teams participate at each of the OHF Championships (the OHF Minor Hockey Member Partner Championship teams within the age category plus the host team).
