This is some of the coldest weather we've seen in years.
While most of us are inside, trying to avoid the brutal cold, others don't have a choice but to stick it out in the arctic outdoors.
Construction crews working out in the arctic air have to come up with creative ways to keep warm.
One crew, working to build an entrance way for a new housing development had an interesting method. They set large tents up around the site to block out the wind and then used generators to pump heat into those tents.
As always when the temperature drops, people who have to be outside wear lots of layers and bundle up.
