A major multi-vehicle collision has turned the Thursday morning commute into a nightmare for thousands of Greater Toronto Area drivers. Emergency crews are currently on scene dealing with a serious crash that has shut down multiple lanes on Highway 401 in Mississauga.
Traffic Gridlock During Peak Hours
The incident occurred during the busy morning rush hour, creating a domino effect of delays across the western GTA. Ontario Provincial Police confirmed they are investigating the collision between Winston Churchill Boulevard and the Highway 407/401 interchange.
Early reports indicate the crash involves several vehicles, though the exact number and severity of injuries remain unconfirmed. Multiple emergency response units, including paramedics and fire crews, have been dispatched to the scene to assist with the situation.
Commuters Face Extensive Delays
The lane closures have created significant backups that are stretching for kilometers. Traffic cameras show vehicles at a standstill in both the express and collector lanes as emergency crews work to clear the scene.
Commuters are being advised to seek alternative routes if possible. The following detours are recommended:
- Use Highway 407 as a toll alternative
 - Take Dundas Street or Burnhamthorpe Road for east-west travel
 - Consider public transportation where available
 
Safety Investigation Underway
The Ontario Provincial Police have not yet released details about what caused the multi-vehicle pileup. Investigators are examining the scene to determine the factors that led to this morning's dangerous incident.
Motorists are reminded to exercise extreme caution when approaching emergency scenes and to maintain safe following distances, especially during peak travel times when traffic conditions can change rapidly.
This is a developing story, and transportation officials warn that cleanup and investigation could extend through the morning commute. Drivers should expect continued delays and check real-time traffic updates before heading out.
