Drivers are being advised to exercise extra caution on Saturday evening due to traffic lights being out at several intersections in Mississauga.

Peel Regional Police reported the power outage shortly after 6 p.m. near Hurontario Street and Derry Road, affecting traffic signals at multiple intersections. The cause of the outage remains unknown.

In a social media post, police instructed drivers to treat all non-functional traffic lights as four-way stops unless otherwise directed.

Hydro One crews are on-site working to restore power, but police have not yet provided an estimated time for when the intersections will be fully operational for both drivers and pedestrians.

Motorists are advised to avoid the area, seek alternate routes, and anticipate possible delays.
