Southern Ontario cold snap persists, wind chills near –35 C

Southern Ontario remains locked in a deep freeze, with wind chills as low as - 35 C and Toronto logging its longest stretch of below-freezing temperatures in 11 years.

A prolonged blast of extreme cold continues to grip southern Ontario, with Environment and Climate Change Canada warning of dangerous wind chills and ongoing health risks.

A level-yellow cold weather warning issued early Saturday states wind chill values of -30 C to -35 C are expected through the morning and afternoon, with similar conditions likely to return overnight.

Extreme wind chills are also expected to bring in blowing snow, which can cause near-zero visibility in some areas.

Environment Canada warns that extreme cold puts everyone at risk, particularly young children, older adults, people with chronic illnesses, outdoor workers and those without adequate shelter.

Frostbite can develop within minutes on exposed skin, especially in windy conditions.

Officials are urging residents to dress warmly, limit time outdoors, monitor for symptoms such as numbness, colour changes in fingers or toes, chest pain or shortness of breath, and to check in on vulnerable family members and neighbours.

Drivers are advised to keep emergency supplies in their vehicles, including blankets and jumper cables.

The cold snap comes as municipalities also contend with hazardous wind conditions.
