Venues of the 2015 Pan American and Parapan American Games

Besides Toronto, fourteen other municipalities in Southern Ontario hosted competitions: Ajax, Hamilton, Innisfil, Markham, Milton, Minden, Mississauga, Mono, Oro-Medonte, Oshawa, Palgrave, St. Catharines, Welland and Whitby.

All venue capacities listed below are found in the strategic framework for transportation published by the Government of Ontario.

In addition there were venues located outside these zones in Barrie, St. Catharines, Palgrave, Minden and Welland.
