Yes - some wildlife population would suffer if we grew to 100 million Canadians. Just not sure when that's become a threshold for much of anything given all the land/animals, etc destroyed for everything else in the world - from Alberta's oilsands to potential Ring of Fire mines in Ontario.
If we have water issues in cities in Canada that aren't caused by terrible planning - then the entire world is basically screwed with all freshwater we have compared to our population.
Does your thought process change if certain populated areas of the world become inhabitable due to climate change?
