A 55-year-old man from Toronto has been arrested for impaired driving causing death, after a two-vehicle collision on Hwy. 401, near Keele St., Ontario Provincial Police say.

Emergency crews were called around 4:30 p.m. on Saturday to the westbound collector lanes of Hwy. 401, just west of Keele St.

Two vehicles were involved, said OPP Sgt. Kerry Schmidt, each with a male driver. One man was pronounced dead at the scene.

Toronto Fire Services Capt. Karen Reid said one person was trapped in their vehicle, but was later removed.

Police have identified the victim as a 39-year-old man from Woodbridge.

The collector lanes have been closed in the area for the investigation, but the express lanes are open, said Schmidt.
