Yes, Paintball Paradise and Prairie Storm Paintball.
First of all you should join these Facebook groups since that's where organization happens:
Saskatoon Airsoft (if he wants to)
Saskatoon Airsoft Buy and Sell (if he wants to)
And I'll pimp my own store here, pretty much the only airsoft store in SK with a wide assortment of guns/accessories/products: www.sasksoftarmoury.ca
which is also in my signature line.
