Airports and airlines are advising travellers flying in or out of any Canadian cities today to check with their airlines before leaving.
"Basically no matter where you are in the [eastern half of the] country right now, if you’re travelling between Canadian cities there’s a very good chance you’re going to have some headaches this morning," B.C. reporter Sherry Aske told CBC News.
Sunday's icy weather is already responsible for more than 120 cancelled flights at Toronto's Pearson International Airport. That number is expected to rise throughout the day, with even more flights delayed. The airport cautions any travellers heading to the airport to give themselves plenty of time today.
The situation isn't much different at the Toronto Island airport with dozens of cancellations and delays, according to the Toronto Port Authority's website.
Meanwhile at Ottawa's Macdonald-Cartier International, travellers can also expect dozens of delays and some cancellations. Montreal-Trudeau is also reporting a similar story with a handful of cancellations and dozens of delays as of Sunday afternoon.
Flyers can find more information about their flights by checking in with an airport's website. However, it's best to call your airline directly to make alternate arrangements.
Air Canada is allowing passengers affected by the storm to rebook without penalty, provided there's enough space. WestJet and Porter Airlines are also allowing their passengers to do the same via phone.
You can reach Air Canada's automated flight system at 1-888-422-7533.
Travellers flying with WestJet can call 1-888-937-8538 to rebook.
Flying with Porter? You can find out more about your flight at 1-888-619-8622.
But it's not just flyers the ice storm is impacting.
Via Rail is reporting delays on the Toronto-Montréal and Toronto-Ottawa routes due to the weather. Riders are urged to check this website for updates, or call 1-888-842-7245. Meanwhile, downed power lines and fallen tree branches are making for tricky driving and are the cause of extensive power outages across the Greater Toronto Area.
For travellers looking for visit friends and family within the GTA, GO Transit is warning its riders that service will be a bit slower today. Trains and buses are both running but trips will take a bit longer than usual.
Environment Canada for its part is advising people to be cautious and not to take any unnecessary risks.
"This will be one of the most heaviest ice rains or freezing rains we have seen in decades," said David Phillips, a climatologist with Environment Canada, in an interview with CTV. "I think it's important to be respectful of it and make sure you don’t do anything foolish."
