The Native Americans were in very large numbers, though much more in the US and less in Canada.

Across North America, there were thousands of settlements, some of which were cities or villages, while some were temporary dwellings. Unlike the common belief, the Native Americans, at least the ones that had a settled lifestyle, were on a relatively similar level of development as the Europeans, and they exploited the continent a lot. The landscape was changing from one place to another because of the type of human activity that was dominant, and what is now the US especially, was much less forested because of agricultural activities than what the Europeans saw after they started to move westward sometime after their initial arrival.
