Canada’s Changing Climate Report 2026: Report Summary

Canada’s Changing Climate Report 2026 provides a scientific assessment of observed and projected climate change across Canada, covering rising temperatures, extreme weather, drought, floods, wildfires, freshwater, glaciers, permafrost, sea ice, sea-level rise and ocean change. Published by Environment and Climate Change Canada, the report assesses how Canada’s climate is changing under different emissions scenarios and provides climate science to support adaptation and risk planning.

Key Takeaways

Canada warmed by an estimated 2.0°C between 1948 and 2023, while Canada’s North warmed by 2.6°C. Since 1970, Canada has warmed nearly twice as fast as the global average, with the Canadian Arctic warming around three times as fast. CCCR 2026_Report Summary-EN-Sep2
Annual precipitation across Canada increased by an estimated 9.7% between 1949 and 2023, rising by 18.9% in Canada’s North, with most of the national increase attributable to human influence on the climate.
Canada is projected to warm by about 0.9°C between 2021 and 2040 regardless of the emissions scenario, bringing average Canadian temperatures to approximately 2.7°C above pre-industrial levels over that period.
Climate extremes are expected to intensify. Summer droughts are projected to become longer, more frequent and more severe across central and southern Canada, while heavier rainfall and stronger atmospheric-river events are expected to increase flash-flood risk.
Canada is already experiencing interconnected climate changes including longer fire seasons, glacier loss, permafrost thaw, declining snow and sea ice, warming and acidifying oceans, marine heatwaves and rising sea levels. Many of these changes will continue even after surface temperatures stabilize. CCCR 2026_Report Summary-EN-Sep2
