An Arctic air mass has gripped much of the country, sending temperatures plunging to dangerous levels.
Widespread windchill warnings were issued across southern Manitoba Monday with windchill values ranging from the -40s to -50s.
According to Environment Canada, windchill values rose above the -40 warning threshold Tuesday, but more extreme cold conditions can be expected later this week.
In Winnipeg, the daytime high will struggle to climb above -20°C for the next several days, so residents are urged to limit any extended periods of time outdoors.
About 18,000 households were without their mail in Winnipeg on Monday as the frigid temperatures forced Canada Post to scrub the mail delivery. Garbage and recycling collection also ran behind schedule as workers had to take breaks from the frigid weather.
The cold snap has also put a strain on a few main homeless shelters who triggered their cold-weather policies, which means no one will get turned away.
