Canada recorded its first -30°C temperature of the season early Thursday morning.
The frigid reading came from Isachsen, Nunavut, marking the first instance of temperatures dipping this low since April 27, 2026, when -30°C was recorded in Rea Point, NU.
This cold snap is linked to the edge of the polar vortex, which has briefly extended into Canada while its core remains centred over Siberia.

However, Canadians should not expect this Arctic air to plunge further south.
While colder air is expected to shift across eastern Canada this weekend due to troughing, the main concentration of the polar vortex will stay on the opposite side of the hemisphere through the rest of this month.
