Toronto gets another blast of extreme cold

The city is grappling with one of the coldest days of the winter.

As of 11 a.m. on Sunday, Environment Canada reported the temperature being –22 C at Toronto Pearson International Airport. With the windchill, it felt more like –38.

The airport advised it passengers to check the status of their flights before proceeding to Pearson.

In particular, Boston-bound flights were being "severely impacted by winter weather," according to a tweet from the @TorontoPearson account.

The city was already under an extreme cold weather alert ahead of Sunday. It was extended, due to the severe cold.
