North America is somewhere in the middle when it comes to its size, as it looks much larger than it actually is due to the fact that the map projection adds extra land when transferring a sphere to a rectangular map. It is smaller than Africa and Asia, but it is larger than Europe and Australia.
Canada is mostly a tundra region. Most people live at the borders of Canada due to climate and trade.
Baffin Island is the only one that is correct you would think Canadian shield It has the name "Canadian" in it but sadly that is not true because there is parts of it in Minnesota and Wisconsin
