Sorry, you can't get ANYTHING for $70...
Hell.. I spent more than $70 just on the cocking handle of my sniper rifle..
You're going to have to greatly increase your budget, but I have a feeling you are under 18.
Airsoft in Canada is generally an 18+ sport, if you're just looking for something to target shoot with, a BB gun would be much more accurate and closer to your price range. Check out your nearest Canadian Tire, Whosale Sports, Cabelas, and look at their range of BB and Pellet guns.
