Hosted by the Urban Climate Alliance (UCA), the Ontario Climate Summit is a gathering of local climate action organizations from across the province to come together and work for stronger climate action in communities across Ontario.
In this 3-day summit, climate activists from across Ontario will connect, build skills, and collaborate to drive inclusive, effective, sustainable, and coordinated climate action in Ontario’s municipalities. Deliberately hosted after the October municipal elections across Ontario, 2026 summit’s focus is Post-municipal-election Climate Action.
