People in central Canada were once again getting out the scarves, mittens and touques as an arctic blast brought extremely cold temperatures right across the region.
Wind-chill warnings were in effect Tuesday for southern Manitoba, most of Ontario and parts of Quebec. The blowing cold Arctic air made it feel closer to -43 C in Portage la Prairie, Man., Tuesday morning.
In southern Ontario, a bitterly cold air mass brought cold temperatures - feeling close to -30 C at times - that were expected to persist through to Wednesday, Environment Canada said.
"A blustery very cold weather pattern which has been quite common this winter has returned again," a special weather statement, warning of blowing snow north and east of Toronto, said.
Airlines issued travel advisories warning the extreme cold could affect flights in Toronto, Ottawa, and Montreal.
Temperatures in the provinces are expected to improve over the next few days.
