Tractor trailer and SUV crash on Highway 400 near Innisfil Beach Road

Blowing snow along Highway 400 near Innisfil Beach Road in Innisfil, Ont. on Wed., Dec. 10, 2025.

Emergency crews are on scene along Highway 400 Wednesday morning after a collision involving a tractor trailer and an SUV just south of Innisfil Beach Road south of Barrie.

Police said units were on their way shortly after the initial call came in.

According to early witness information shared with OPP, both drivers were able to get out of their vehicles.

Innisfil Fire Rescue Service confirmed one person has been injured, though the extent of those injuries remains unclear.

Fire Chief Brent Thomas confirmed to CTV News both vehicles remain in the ditch on the southbound side of the highway. Thomas said Innisfil fire crews currently have trucks and blockers positioned to protect the scene until Ministry of Transportation blockers arrive.

As a result, traffic is moving but slow through the area. Drivers on Highway 400 are being asked to use caution and be prepared for sudden slowdowns as responders assess the crash and manage traffic around it.

It has not been determined whether weather played a role, but the collision comes as a snowfall warning remains in effect for the region.

Environment Canada said 10 to 15 centimetres of snow is possible, with heavy and blowing snow reducing visibility at times.

The agency warned that travel conditions are already challenging and that roads may be difficult to navigate as the Alberta clipper continues to move through. Flurries and additional bursts of lake-effect snow may develop into the evening.
