Which of the following is NOT a territory in Canada?

The Prairie Province is the correct answer to identify as not being a territory in Canada. In Canada, the term "prairie provinces" refers specifically to the regions of Alberta, Saskatchewan, and Manitoba, which are actually classified as provinces, not territories.

Territories in Canada, including Yukon, Northwest Territories, and Nunavut, are distinct because they are governed differently from provinces. Territories have a more direct relationship with the federal government and generally have less autonomy compared to provinces, which have their own systems of government established by the Constitution.

Understanding the difference between provinces and territories is essential in grasping the political landscape of Canada. The Prairie Province does not fit into the category of territories, making it clear that it is the answer to the question.
