Hwy 400 Accident Today TORONTO AREA — Traffic authorities are responding to a major accident on Highway 400 north of Toronto, where a crash has prompted closures and slowed traffic along the busy provincial route, Ontario Provincial Police (OPP) and local emergency crews confirmed.
The collision, involving multiple vehicles, occurred near a ramp in the Vaughan area, forcing at least part of the highway or adjacent ramps to close while officers, tow crews and medical personnel work at the scene. Initial reports from police indicated the crash may be linked to suspects fleeing from a home-invasion investigation, leading to loss of control and a collision on the southbound Highway 400 on-ramp from Major Mackenzie Drive.
York Regional Police say that shortly before the crash, officers were alerted to a home invasion and stolen pickup; the suspects then crashed through a guardrail on the highway ramp before fleeing on foot. One suspect has been arrested, and investigators are searching for others believed to be at large.
Officials are urging motorists to expect delays and possible detours in the affected area as cleanup continues and damaged infrastructure is repaired. The ramp closure has already impacted morning traffic patterns, with repairs expected to extend into midday.
Police have not yet released details on injuries sustained in the crash, and the investigation remains active. Drivers are advised to use alternate routes and follow updates from OPP and York Regional Police for the latest information.
