Canada plunges into a deep freeze, disrupting flights and classes
OTTAWA (AFP) - Extreme cold in Canada on Monday disrupted flights and school classes, caused widespread power outages and created havoc on roads.
Temperatures as low as minus 50 deg C with a wind chill - colder than the surface of Mars - plunged the western Prairies region into a deep freeze, heightening risks of frostbite and hypothermia.
Toronto, Montreal and the capital Ottawa braced for a flash freeze with temperatures forecast to drop as much as 40 degrees in less than 24 hours, after locals awoke to unusually warm temperatures (above freezing) and rain.
Environment Canada warned of "treacherous" travelling conditions.
