TORONTO School buses were cancelled and commutes were delayed in parts of Ontario after a winter storm dumped upwards of 25 centimetres of snow on Toronto and surrounding areas over the course of 24 hours.
Provincial police said there were multiple collisions reported across the Greater Toronto Area on Tuesday morning as a result of the slippery roads and blowing snow.
And while schools remained open in the Toronto and Durham school districts, buses were not running.
West of Toronto, the Halton District School Board closed schools because of the weather.
Meantime, a frigid arctic air mass produced extremely cold temperatures on Monday night and into Tuesday morning, setting records in parts of northern Ontario.
The temperature at Geraldton Airport in Greenstone, Ont., on Tuesday morning was -47.7 C, smashing past the 1991 record of -41.6.
Meanwhile, temperatures in Sudbury plummeted to -37.1, breaking the record of -35.6 set in 1925.
