Which area has the least population density in Canada?

The area with the least population density in Canada is found in the mountains. This region includes the rugged terrain of the Rocky Mountains and other mountain ranges, which are characterized by difficult living conditions. The challenging geography, including steep slopes, limited access to resources, and harsh weather conditions, makes it less feasible for large populations to settle. As a result, mountainous regions typically have very few residents compared to more hospitable areas, such as urban centers or plains where infrastructure and resources support higher population densities.

In contrast, populated areas such as cities have a high population density due to the availability of jobs, services, and amenities. The northern border has a low population density, but it is often associated with more remote communities and indigenous populations rather than the vast and uneven terrains of the mountain regions. The southern border, being closer to urban centers and the United States, tends to have a higher density due to economic opportunities. Hence, the mountains unequivocally represent the area with the least population density in Canada.
