The Ontario Parasport Games were first delivered in 1975 in the City of Cambridge. Since then, the Games have grown to over 400 athletes competing in 11 sports. The Niagara 2025 Ontario Parasport Games will be the 44th edition.

Games Ontario is a brand under the Government of Ontario and the Ministry of Sport. The 2025 Ontario Parasport Games are supported by the Ontario Government through its Games Ontario program. This program delivers and supports multi-sport events, including the Ontario Winter and Summer Games for youth, the Ontario 55+ Winter and Summer Games and the Ontario Parasport Games.

The 2025 Ontario Parasport Games are led by a Games Organizing Committee (GOC). The committee, formed by Sport Niagara, includes enthusiastic community leaders that will help shape the Games and create a unique event to welcome participants and spectators across Ontario.
