Four dead in multiple Quebec road accidents

At least four people are dead after three separate road accidents on Saturday night in Quebec.

Two pedestrians, both 54, were struck and killed while walking along the shoulder of Highway 235 in Farnham, Que., about 60 kilometres southeast of Montreal.

Police said the accident happened at 6:40 p.m., just after dark, and the driver likely didn't see them.

Speed, alcohol likely factors in St-Colomban crash

A passenger died after a driver lost control of his vehicle in the town of St-Colomban, just north of Mirabel.

The crumpled car ended up in a private driveway on a quiet residential street.

Police said speed and alcohol may have contributed to the incident.

Mirabel police witnessed the crash.

Because the municipal force may have played a role, the Quebec provincial police force has been called in to do an independent investigation of what happened.

Traffic disrupted on Highway 15 north

In Montreal, six people were taken to hospital with serious injuries after an early morning accident on Highway 15, near the La Vérendrye Boulevard exit.

At around 3:30 a.m. Sunday a motorist drove onto an exit from the northbound highway, heading in the wrong direction.

That car collided head-on with another car, which was carrying five people.

Northbound lanes of Highway 15 were shut down for several hours while police tried to piece together what happened.
