As a massive snowstorm moves through the province, Ontario Provincial Police officers say they have responded to approximately 200 crashes on highways in the Greater Toronto and Hamilton Area.Officers also reported that around 125 vehicles ended up in ditches. They said most of the collisions happened after snowfall began in the region as much of southern Ontario remains under a snowfall warning.While standing along Highway 401 near Highway 400 Thursday morning and filming a video for social media, OPP Sgt. Kerry Schmidt showed a two-vehicle crash and said it’s an example of vehicles “pinballing off of each other as they’re hitting the walls” and colliding.“Be careful out there. Drive to the conditions, and the conditions are miserable right now. We just need everyone to do their part,” he said.“We’re responding as quickly as we can. Traffic volume is a lot lighter than a typical day, but we’ve still got lots of volume out there.”Schmidt suggested anyone stuck in the snow should temporarily disable the vehicle’s traction control to try to get moving. He also urged people to slow down and to focus on navigating the roads.Related:Powerful winter storm sweeps Toronto with up to 35 cm forecasted snowfallCancellations, delays reported at Toronto Pearson, Billy Bishop airports due to snowstormSnowstorm of ’26 in photos: Powerful winter storm hits Toronto, GTADVP reopens after hours-long closure as storm causes chaos on GTA roads“If you don’t need to be on the roads, this is a great day to take it easy and not be out there,” he said.“Plows are out there.
