Traffic was disrupted on Highway 401 in Toronto following a reported collision in the eastbound collector lanes near Leslie Street, with lane restrictions affecting motorists travelling through the area.

According to Ontario 511 traffic information, the crash was reported on the eastbound side of Highway 401 near Leslie Street. The incident affected the left portion of the collector lanes, resulting in the left lane and left shoulder being closed while the response was underway.

The collision occurred along one of the Greater Toronto Area’s busiest highways, where even a limited lane restriction can quickly contribute to congestion. Drivers approaching the affected section were advised to reduce their speed, remain alert and allow extra time for their journeys.

At the time of the reported update, authorities had not released confirmed information about the number of vehicles involved, possible injuries or the circumstances that led to the collision. The identities of anyone involved had also not been publicly released.

The lane closures were being maintained while crews responded to the incident and worked to manage traffic around the affected area. Eastbound motorists travelling toward Leslie Street were encouraged to monitor traffic conditions and consider alternative routes if delays increased.

Highway 401 is a major transportation corridor through Toronto and the wider GTA, carrying large volumes of traffic throughout the day. As a result, incidents that reduce the number of available lanes can have an impact beyond the immediate crash location.

Motorists approaching an active collision scene should follow posted signs, obey directions from emergency and traffic-management personnel and avoid sudden lane changes. Drivers should also leave sufficient space between vehicles, particularly where traffic is slowing near the incident.

Ontario 511 provides motorists with current information about highway collisions, lane restrictions, closures and other road conditions. Conditions can change as emergency crews clear vehicles and complete their response.

Further information about the Highway 401 collision near Leslie Street, including whether anyone was injured and when the affected lanes reopen, may become available as the response continues.

For now, motorists travelling eastbound through the area should expect possible delays and exercise caution while the lane restrictions remain in place.
