Answer:
Canada's population is unevenly distributed because big portion of the country is dominated by taiga and tundra, but also the industrial centers of the US have had a big impact because of the economic influence.
Step-by-step explanation:
Canada is the second-largest country in the world but its population is nowhere near second place, instead, it is smaller than countries that have much smaller territories than most of the provinces in Canada. Not just that the population is very small for the size of the territory, but it is also highly concentrated along the southern border of the country, with the interior and northern parts having very few people living in them.
The two main reasons for why the population is mostly concetrated in this part of the country is that the climate conditions are the best and the US's industrial and economic centers are nearby. This is the only part of Canada that has continental and maritime climates, unlike the very harsh rest of the country, so naturally, people chose this area. Also, the southwestern and southeastern parts of the country are close to the industrial and economic centers of the US, and this has led to big economic development in these parts of Canada, and where the economy is the strongest the people are most attracted.
