Extreme Cold Warning in effect for:

  • Barrie - Collingwood - Hillsdale
  • Midland - Coldwater - Orr Lake
  • Orillia - Lagoon City - Washago

Very cold wind chill values developing this evening.

Temperatures are forecast to rapidly fall through the day today. As a result, by this evening wind chill values near minus 30 are forecast to develop.

As temperatures fall even lower tonight, even colder wind chill values near minus 35 are likely into early Saturday morning.

After moderating somewhat Saturday afternoon as winds ease, extreme cold wind chill values to minus 30 may return for a few areas Saturday night into Sunday morning.

Extreme cold puts everyone at risk.

Watch for cold related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes.

Dress warmly. Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant.

If it's too cold for you to stay outside, it's too cold for your pet to stay outside.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ONStorm.
