Hi bman ...
My basement in Ottawa got up to 21 C / 70 F in the summer. Guess it depends on how deep your basement is dug and how often you use the AC. I am 8 feet below grade. Apparently if I went down a few more feet I would hit 12-14 C. My builder suggested I pick axe the basement floor in my cellar and let it passively cool ... I settled for a cooling unit.
When I walled in my cellar I tested the temperature a few weeks without the cooling unit and it didn't drop much.
