Canadian military helicopters have been used to rescue motorists trapped by snow on an Ontario highway, some for more than 24 hours.
Police estimated more than 200 people remained stranded after a flash snow storm stopped traffic on a 30 kilometre stretch of road, the BBC reports.
Motorists rescued from Highway 402 were taken to warming centres, but Defence Minister Peter MacKay told Canadian media some did not want to leave their vehicles.
A state of emergency was declared in Lambton County southwest of Toronto, where the motorists have been stranded.
Weather officials say a snow squall in some areas of Ontario created zero visibility, with wind chill values of -20°C.
