Environment Canada has issued a special weather statement for the city of Toronto and the southern Ontario region, warning that a major storm system is expected to affect the area Wednesday and Thursday.
"A low pressure system developing over the southern states will track northeast to reach southern Ontario Wednesday," the statement reads.
The storm is expected to bring rain and significant snow to some areas as well as possible freezing rain.
The locations that will get the heaviest snow and the areas most likely to get freezing rain are uncertain at this time and will depend on the tracking of the low-pressure system, according to Environment Canada.
The agency is advising people to refer to weather statements and check local forecasts for updates as the storm system evolves.
