Step-by-step explanation:
1) Many Southern regions in Canada are infertile or extremely cold. However, the more Southern regions are warmer. Warmer regions makes the climate suitable for living because there can be more agriculture and farm land. With nearby agriculture, inhabitants will not have to outsource their food, resulting a cheaper source. Additionally, since the border is near the United States, there is a larger access to trade. The shipments do not have to be transported from a longer distance, making it easier.
2) Since Canada is close to the United States, it is increasingly efficient and easier for Canada to trade with the U.S. Trade shipments do not have to be exported over long distances.
