Weather alerts across the GTA and southern Ontario Environment Canada weather alerts in the GTHA and parts of southern Ontario Friday morning, Nov. 28, 2025. Environment and Climate Change Canada has introduced a new colour-coded, tiered weather alert system: Yellow: Hazardous weather may cause damage, disruption or health impacts. Orange: Severe weather is likely to cause significant damage, disruption or health impacts. Red: Very dangerous and possibly life-threatening weather will cause extreme damage and disruption. An area with a dotted line around it is a watch. A solid line is a warning. An area under a weather statement is in grey.

“Intense bands of lake effect snow off of Georgian Bay will affect the area today and tonight. These bands are not expected to shift much. Where the bands lock in, very heavy accumulations will be possible,” Environment Canada said in its advisory.

“Strong winds are also expected, reducing visibility to near zero at times in local blowing snow.”

Widespread school bus cancellations have been reported in Simcoe County as a result of the storm.

Environment Canada said “lake effect activity” should diminish in intensity either tonight or Saturday morning.

The national weather agency is urging people in these areas to avoid non-essential travel during the winter storm.

The City of Toronto will come away from the weather event mostly unscathed. Environment Canada says there is a risk of flurries in Toronto throughout the day but no significant accumulation is expected.

Toronto will see a high of 0 C on Friday but to start out the day, it will feel closer to -8 with the wind chill.
