Toronto will feel like -20 at its warmest today. Here is what you need to know about this week’s cold snap.

Five sites are currently open across the city.

Monday is shaping up to be the coldest day of the year for Toronto as bitter arctic air settles over central and eastern parts of Canada and the United States.

Toronto will see a daytime high of -10 C today, feeling closer to -20 with the wind chill.

The frigid weather is expected to stick around for the next few days. The national weather agency says Toronto will see the daytime high rise to just -12 C on Tuesday and -9 C on Wednesday.

In parts of northern Ontario, including North Bay and Sudbury, the mercury has plunged to around -30 C.

CP24 Meteorologist Bill Coulter noted that the bitter cold this week isn’t going to break any record.

“We’ve got to put this in context,” he said.

“I was looking back to the 70s and overnight temperatures were dipping down to the mid -20s if not low -30s and so for some of those records we will not come close to breaking them.”

While some areas of the province will see some lake effect snow, Toronto will remain relatively free of active weather, Coulter said.

There is a 30 per cent chance of flurries in Toronto this morning.

Torontonians will enjoy some sunshine later this week with a mix of sun and cloud in the forecast on Tuesday and Wednesday.
