The current blast of severely cold weather gripping the province has already wreaked havoc on the TTC in Toronto, caused hundreds of collisions across the GTA, and made Ottawa the coldest national capital in the world.

Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frostbite and hypothermia. Frostbite can develop within minutes on exposed skin, especially with wind chill values this low. Pets should also stay inside.

As of 10 am it is -18.6°C in Toronto, -32°C with the windchill.
