Major Highway 400 Crash Causes Significant Delays
A multi-vehicle collision has severely impacted the Thursday morning commute for drivers south of Toronto. The incident occurred on Highway 400 southbound, prompting a significant emergency response.
Ontario Provincial Police confirmed that the crash has reduced southbound traffic to just a single lane. The collision involved multiple vehicles, though the exact number has not been officially released by authorities at this time.
Emergency Response and Investigation Underway
The OPP responded to the scene early on the morning of November 20, 2025. Emergency crews, including paramedics and tow trucks, were dispatched to handle the situation and clear the wreckage.
Police have not yet released information about potential injuries resulting from the crash. The investigation into the cause of the multi-vehicle collision remains active as officers work to determine what led to the incident.
Commuters Face Lengthy Delays
The lane reductions are creating substantial backups for morning travelers. Commuters are experiencing major delays throughout the highway corridor and are being advised to seek alternative routes if possible.
Motorists who must travel through the area should expect significantly extended travel times until all lanes can be reopened. The OPP has not provided an estimated time for when full access to the highway will be restored.
This incident serves as another reminder of the importance of maintaining safe following distances and adjusting driving behavior during busy morning commute hours.
