Toronto’s medical officer of health has issued an extreme cold weather alert as the temperature is expected to reach -20 C with the wind chill on Monday.
The advisory is issued when the temperature is forecast to reach -15 C or colder, or with a wind chill of -20 C or colder.
The conditions are expected to remain frigid Monday evening with a low of -12 C and -20 C with the wind chill overnight.
The extreme cold weather arrives as strong wind gusts subside in the Greater Toronto Area. Parts of Southern Ontario were under a wind warning on Sunday due to winds of up to 100 km/h in some regions.
The cold alert triggers weather services for homeless people, including TTC tokens for people to get to shelter, increased street outreach, and a direction to shelters to relax any service restrictions in place.
