Freshwater Supply Challenges Threaten Canada’s Security, Internal Federal Memo Says
The memo says climate change, pollution and aging infrastructure are straining supplies as Canada weighs a national water security strategy.
An internal government memo warns that freshwater pressures threaten Canada's "long-term security and prosperity" if left unaddressed, with some regions facing restricted water supplies even in the Great Lakes-St. Lawrence River basin.
Most of Canada's renewable fresh water drains northward, away from economic centres within 300 kilometres of the Canada-United States border, while freshwater ecosystems face stress from climate change, pollution, and overconsumption.
For the 2021 to 2023 period, 51 per cent of 165 monitoring sites in southern Canadian rivers rated as fair to poor, despite Canada holding 20 per cent of the world's surface fresh water.
Environment Minister Julie Dabrusin identified a national water security strategy as "a mission critical priority" in response to Prime Minister Mark Carney's call for cabinet objectives, with public consultations concluding Oct. 25.
More than 40 per cent of the Canada-United States border crosses water, and the memo warns "new water-related disputes could emerge and become more frequent" as freshwater supplies shrink across North America.
