(CNN) -- 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.
"You really felt almost despair," said Brandon Junkin, who spent nearly 24 hours stranded before being rescued Tuesday afternoon after he heard a helicopter hovering over his immobilized truck. He had run out of gas and was without anything other than a blanket to help him through the ordeal.
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. CNN
