Answer:
Due to its cold climate, over 75% of Canada is unsettled.
Step-by-step explanation:
Canada is a country with a very large territorial extension, being the second largest country in the world, only behind Russia, with 6,204,186 square miles. But, despite this territorial extension, it has only 38 million inhabitants, when countries like the United States and China (of similar territorial extension) have 330 and 1.6 billion people respectively.
Therefore, the country has a low population density: 10 inhabitants per square mile, of which two-thirds live near the US border.
This happens for two fundamental reasons: the first is that 70% of Canada's trade occurs bilaterally with the United States, so the connection between the cities of both countries is important.
The second, and most important, is the country's climate. Winter can be severe in many regions of the country, particularly inland and on the Canadian prairies, which have a continental climate, where average daily temperatures are close to -15 ° C, but can drop below -40 ° C with a sensation extremely cold thermal. Inland, snow can cover the ground for almost six months of the year (more in the north).
In this way, the regions to the north of the country are practically uninhabitable due to the harshness of winters, with which almost the entire population lives in the southern region of the country.
