Did you know that California (39 million) has more population than Canada (36 million)? The map above displays the area comparison and map below shows how Canada’s population would fit into California. For example, most Canada’s population is concentrated in the two provinces of Ontario and Quebec – these provinces have approximately the same population of southern California. Even though Canada has an area larger than the entire United States, its population can fit into California with room to spare. Side note: California also has a substantially larger economy with a 2.6 trillion nominal GDP compared to 1.5 trillion for Canada (2017).
