An extreme cold warning remains in effect for Toronto and the Greater Toronto Area ahead of several days of frigid conditions.

Environment Canada issued the warning Thursday morning ahead of an expected temperature drop to a low of -23 C overnight, with the wind chill making it feel like -30.

The warning is in addition to an extreme cold weather alert issued by the city earlier Thursday morning.

"A strong cold front is crossing southern Ontario and is ushering in much colder temperatures and gusty north winds," the warning states. "Wind chill values this afternoon are generally expected to be between -20 C and -30 C across most of southern Ontario."

Though many residents are likely already sick of the extreme cold, the conditions won’t improve any time soon, with Environment Canada calling for lows of -11 C Friday, - 5 C Saturday and -17 C Sunday.

“This will be the coldest weekend of the winter so far,” CP24 weather specialist Patricia Jaggernauth said Thursday night.

Snow is also possible on Friday and Saturday, Environment Canada said.

A high of -10 C and sun is forecast for Family Day.

“The temperature will slowly rebound coming out of the long weekend, but will still be below seasonal,” Jaggernauth said.

More snow and temperatures of -7 C and -8 C are expected on Tuesday and Wednesday, respectively.

During an extreme cold weather alert, additional services are activated for the homeless including the addition of extra shelter spaces, increased street outreach and the opening of two 24-hour warming centres.
