Canadian police and military teams were working Tuesday afternoon to rescue about 300 people stranded after what a local official termed the most brutal storm to hit the Ontario region in 25 years.
    Some people had been stuck in their vehicles for more than 24 hours following blinding snow that piled up so high it made it almost impossible to open vehicle doors.
    Ontario Provincial Police initially reported about 360 vehicles and about 300 people had been stranded near Sarnia, Ontario, on Highway 402 — a major thoroughfare linking the U. S. -Canada border to London, Ontario.
    Some of those people have since been rescued, but Sarnia Mayor, Mike Bradley, said it could be another 24 hours before everyone is taken to safety.
