Wardrobe Recommendations
This is still full winter gear weather:
-
Thermal base layer + warm mid-layer + windproof parka
-
Mitts (warmer than gloves), insulated boots, and warm socks
-
Face covering (neck gaiter/balaclava) for wind chills near -30
-
If driving outside town: keep blankets, a phone charger, and booster cables in the vehicle—cold is hard on batteries and small delays can become dangerous.
Weather Trivia
When temperatures drop below about -20°C, snow often becomes drier and squeaky underfoot. That “squeak” is caused by brittle snow crystals rubbing and breaking—classic Northern Ontario winter sound effects.
