“headline”: “Toronto Snowstorm & Snow Squall Live: 150+ Crashes, Flight Delays and Severe Warnings Across Ontario”
Updated: December 11, 2025 • Toronto, Ontario
Toronto is facing one of its most disruptive winter days of the season as a fast-moving Alberta clipper sweeps across Ontario, bringing heavy snow, dangerous travel conditions, flight delays at Pearson and a severe snow squall threat across cottage-country communities. Environment Canada has issued a special weather statement for Toronto and a snow squall watch stretching from Barrie to Innisfil, warning that travel may become “extremely hazardous.”
What We Know So Far
- Toronto expecting 10 cm of snow, with some GTA regions seeing up to 15 cm
- More than 150 collisions reported since 5 a.m., OPP says
- Pearson Airport experiencing widespread delays
- Snow squall watch for Barrie, Innisfil and nearby regions
- Two OPP officers injured in Highway 403 crash investigation
- City-operated warming centres open across Toronto
GTA Roads Gridlocked as OPP Reports 150+ Crashes
The morning commute quickly deteriorated across the Greater Toronto and Hamilton Area as snowfall intensified. By 12:55 p.m., the OPP Highway Safety Division reported approximately 150 collisions caused by slick roads, low visibility and drivers moving too quickly for conditions. Emergency services are also experiencing delays, with tow trucks and first responders stretched thin due to volume.
Officers are urging drivers to slow down, leave extra distance and avoid unnecessary travel until plows can catch up. Live highway updates shared by OPP on official channels show multiple ongoing investigations across the 401, 403, QEW and 407 corridors.
Pearson Airport Facing Delays as Snow Intensifies
Toronto Pearson International Airport is reporting multiple delays as crews work to maintain runways during the heaviest snowfall period. Passengers are being advised to check their flight status directly through the Pearson live departures board before travelling.
The airport cautioned that de-icing operations may add additional wait times. Travellers heading to the airport are strongly encouraged to leave early and account for road delays across the GTA.
Severe Snow Squall Watch for Barrie & Innisfil
While Toronto deals with steady but manageable snowfall, central Ontario is bracing for a much more dangerous setup. Environment Canada has issued a snow squall watch for Barrie, Innisfil and surrounding communities, warning of 30 to 50 cm of snow and visibility dropping to near zero at times.
The alert—coded orange under the agency’s updated colour system—indicates severe travel disruption is likely. The combination of northwesterly winds and lingering moisture from Georgian Bay is expected to intensify squalls through Thursday night, with conditions improving by Friday morning.
OPP Officers Injured in Highway 403 Crash
Further west, two OPP officers suffered minor injuries after their cruisers were struck while responding to an earlier collision on Highway 403 near the Highway 53 exit. Both officers were taken to hospital as a precaution and are expected to recover.
Police are once again reminding drivers to move over for emergency vehicles and avoid sudden braking on slippery roads.
Toronto Opens Warming Centres
With temperatures dipping and wind chills intensifying, the City of Toronto has opened warming centres to assist vulnerable residents. The latest list of locations and hours can be found through the city’s emergency weather response page.

What Comes Next?
Toronto will see snowfall ease by late evening, but roads may remain icy overnight. Environment Canada forecasts lingering flurries into the morning hours before temperatures drop further on Thursday.
Drivers, transit riders and air travellers should continue to monitor updates from Environment Canada, Pearson Airport and OPP regional units as conditions evolve.
