how does the climate of canada impact different human activities relating to population distribution or density or economic activities?

I belive the climate of Candada impacts human population distributions because it is cold. Canda has long months of winter which can be a good or bad thing depending on the person. People visit or live in Canda because of the season. This cold weather can bring skiing, hockey, or people wanting to sled. These also bring economic activites because they can produce gear for these outdoor activites. This brings in more buisness for outdoor activites too. Though it's not just the winter though, fall is another popular time in Canada that brings many people there to see the amazing leaves changing color. Because of candas 4 seasons people come and go because of the cold climate. This can be a negative thing or a postitive thing.

Explanation: I myself live in a cold place that happens to be below canada. And I see people move because it's too cold or move here because they enjoy the cold. This also happens to cause buisnesses that relate to the place to pop up too. If a place has winter there is most likely going to be a ice skating ring somewhere in the area or a ski logde around.

I hope this helped! This is all just my opinion and my knowlege of the area!
