2025 Ontario Water Leaders Summit

The Great Lakes and St. Lawrence Cities Initiative is hosting its Ontario Water Leaders Summit in Halton Region. This unique event will bring together more than 100 municipal, Indigenous, corporate, and environmental leaders from across the province to explore community-based solutions for strengthening our economy, climate resilience, and freshwater stewardship.

The 2025 Ontario Water Leaders Summit will bring together speakers and presenters for a day of learning, dialogue, and networking. Together, we’ll examine how Ontario can leverage its Great Lakes advantage for sustainable economic development and how our communities can grow more resilient in the face of a changing climate and world of uncertainty.
