In the Arctic territory of Nunavut, the report projects winter warming of more than 10 °C, a shift that would dramatically alter the region’s snow and ice cover.

The same study predicts that glaciers in western Canada will lose over 75 % of their ice, and that there is more than a 60 % chance the central Arctic Ocean will be ice‑free in September.

Further south, central and southern Canada can expect summer droughts that are longer, more intense and more frequent, while the frequency and intensity of flash floods and atmospheric rivers are also set to increase.

The fire season is projected to lengthen, and the analysis finds that Canadian wildfires are now roughly twice as likely as they were in the recent past.

"We do still have some agency," said Nathan Gillett, a research scientist with Environment and Climate Change Canada and one of the report’s authors. "Where emissions go from here will affect how temperatures evolve through the century and whether we can stabilize temperature or whether it just keeps increasing."

Together, these changes could reshape daily life: longer fire seasons may threaten homes, stronger floods could damage roads and bridges, hotter winters may affect transportation and traditional activities in the North, and shrinking glaciers could reduce fresh water supplies for communities downstream.
