Environment Canada has also placed the Greater Toronto Area under a special weather warning, in what is shaping up to be the first major snowfall of the season, with about 10 centimetres of snow expected to fall in areas including Waterloo, Hamilton, Niagara, Brantford and Woodstock.
The government department, as of 9:30 a.m. ET, placed Toronto under a snowfall warning, forecasting 15 to 20 centimetres, compard to the 10 centimetres expected earlier.
The same warning is in effect for regions near Georgian Bay to the Algonquin and North Bay areas.
Looking further east in Ontario, Ottawa is expected to see about 15 to 20 centimetres on the ground by Thursday afternoon.
At Toronto's Pearson airport, about 80 flights have been delayed due to weather, mainly incoming flights from the eastern U.S. and the Maritimes. Airport officials are asking passengers to please check flight statuses before arriving.
The snow, the result of a low pressure system that moved northwest from Cape Cod yesterday, is forecast to taper off later this afternoon over central and southwestern Ontario before ending at about midnight.
Meanwhile, torrential rain that flooded roads and bridges across the Maritimes is slowly moving away, but high winds and rain continue to plague parts of the region.
Coastal rain and winds
Environment Canada meteorologist Jeremy March said although the biggest punch packed by the weather system had passed, rain continued to fall in eastern Nova Scotia as well across eastern and northern New Brunswick and most of Prince Edward Island.
"The rain that's happening over the Maritimes will weaken and move off over to Newfoundland later today," said March.
March said that as of 2 a.m. AT, parts of central and western Nova Scotia had received over 100 millimetres of rain while the Grand Manan Island area of southern New Brunswick had been drenched by nearly 160 millimetres and 120 millimetres had fallen in parts of western P.E.I.
In Halifax, a portion of the Bedford Highway that was shut down because of flooding remained closed early Thursday.
Power crews were also continuing to deal with thousands of outages in western and northern New Brunswick.
Out west, Environment Canada is warning of freezing rain in parts of northern Alberta.
In B.C., heavy rain in the southern coastal area continues to pose problems, but an unusually high tide has not caused the flooding that was feared.Suggest a correction
