Explanation:

Canada is the second-largest country in the world, but its population is not what would be expected for such a vast territory, in fact, Canada is a country with low population density. The majority of the population in this country is concentrated in the southern, southeastern, and southwestern part, while the rest of the territory is mostly empty. There are multiple reasons for this uneven population concentration, with the major being the climate, economy, and connectivity.

The aforementioned areas where the population is concentrated are the only ones that provide relatively good living conditions. These are the only parts of the country where agriculture is possible. Coming out on sea (that doesn't freeze in winter) is very beneficial for trade but also makes the climate milder. And last but not least, these are the areas that border the United States, the biggest economy in the world, which in turn has a big influence on the high development of the Canadian economy near the border.
