TORONTO -- Hundreds of North York residents may be without power until Monday evening as crews work to repair a hydro pole that was knocked over by a falling tree.

Toronto police say that a large tree fell on a hydro pole near Steeles and Bayview avenues Monday morning, knocking down live wires. Multiple traffic lights in the area were shut off as a result.

According to Toronto Hydro, about 500 to 1,000 customers in the area are now without power.

Officials say the damage is “extensive and involves complicated repairs.”
