Choose two of canada's regions and compare their physical features , economic activities , and population distribution

Central Canada (sometimes the Central provinces) is a region consisting of Canada's two largest and most populous provinces: Ontario and Quebec. Geographically, they are not at the centre of the country but instead toward the east. Due to their high populations, Ontario and Quebec have traditionally held a significant amount of political power in Canada, leading to some amount of resentment from other regions of the country. Before Confederation, the term "Canada" specifically referred to Central Canada. Today, the term "Central Canada" is less often used than the names of the individual provinces.
Atlantic Canada is the region of Canada comprising the four provinces located on the Atlantic coast, excluding Quebec: the three Maritime provinces – New Brunswick, Prince Edward Island, and Nova Scotia – and the easternmost province of Newfoundland and Labrador. The population of the four Atlantic provinces in 2016 was about 2,300,000[1] on half a million km2. The provinces combined had an approximate GDP of $110.308 billion
