Environment Canada has ended its extreme cold warning for Toronto, though by mid-morning temperatures were still hovering around – 20 C, with light winds making it feel a few degrees colder. 

The extreme cold warnings issued earlier by the weather agency for the GTA and most of southern Ontario were called off at about 10:30 a.m., though an extreme cold weather alert from the city remained in effect.

Temperatures are expected to reach a high of –10 today, well below the seasonal average but an improvement over Saturday's bitter cold. Temperatures are expected to improve on Monday. 

The city issues its cold weather alerts when temperatures are forecast to hit –15 or –20 with the wind chill.

Residents are encouraged to dress in warm layers and to call or visit friends, neighbours and family who might be having trouble with the cold weather. Infants and young children, the homeless, people who work outdoors and those with heart or respiratory illnesses are among those at risk, officials say. 

During such alerts extra effort is made to help homeless people to get off the street and into shelters. From Jan. 1 to Feb. 29, the city funds two drop-in centres that are open 24 hours.

If you see someone on the street who needs help with the cold call 311 or, for medical emergencies, 911.
