Final answer:
Atlantic Canada is a slowly growing region, contrasted with other parts of Canada such as Ontario which have higher population densities and growth rates.
Step-by-step explanation:
Atlantic Canada can be classified as what type of region? When assessing the patterns of population growth or decline for Canada's various regions, Atlantic Canada is often considered a slowly growing region. This is in contrast with areas like Ontario, which has a larger and denser population due to its proximity to the border with the United States and is part of the reason why Ontario is sometimes informally dubbed as 'South Canada.' Additionally, Atlantic Canada's growth is not comparable to the rapid population increases seen in some of the more southern and western states in the United States. The population in Canada, as in the United States, tends to be clustered in cities, and a majority of Canadians live close to the US border. However, regions like Atlantic Canada do not see the same level of population density or growth due to factors such as economic opportunities, climate, and geographic location. Therefore, the correct answer to the student's question in the provided context is (c) slowly growing.
