Ottawa – The Great Lakes Freshwater Ecosystem Initiative combines science and action to address environmental challenges affecting Great Lakes’ water quality and ecosystem health by supporting local projects. Through the Canada-Ontario Agreement on Great Lakes Water Quality and Ecosystem Health (2021–2026), the governments of Canada and Ontario support delivery of the commitments in the Canada–US Great Lakes Water Quality Agreement.
The Great Lakes Water Quality Agreement (GLWQA) was signed in 1972 and is an agreement between Canada and the United States. It contributes to the quality of life of millions of Canadians by identifying shared priorities and coordinating actions to restore and protect the Great Lakes.
Following Canada’s announcement in 2023 of $420 million over 10 years in new resources for the Great Lakes Freshwater Ecosystem Initiative, this funding will support accelerated action under the Canada Water Agency-led Freshwater Action Plan to restore and protect the Great Lakes.
The recent round of allocated funding in 2024–2025 will support 50 projects over the next 4 years with a special focus on the following priorities:
- Restoring water quality and ecosystem health in Great Lakes Areas of Concern (AOCs)
- Preventing toxic and nuisance algae
- Restoring and protecting critically important coastal areas, including wetlands
- Reducing releases of harmful chemicals
- Supporting community-based science
- Increasing participation of Indigenous peoples in governance, stewardship, and monitoring
- Advancing Great Lakes governance, accountability, and reporting mechanisms
