Holy cow! That is REALLY expensive. I thought $0.10 a cricket at the local shops here was a bit much. When I was feeding crickets, I switched to a supplier that would email them in bulk (about 500 at a time), which would last me 1-2 weeks if I cared for them properly. It is WAY more affordable, and not too hard to keep them. I'm not sure about online bulk suppliers for Canada, but I used LLLReptile (but they're based here in California).
As the last poster mentioned, I just went with starting my own roach colony. I had too many cricket escapees, which gets quite annoying (even if the cats like having mobile toys in the house). I went with dubias as they can't crawl glass, can't fly, and don't smell. Not one escapee!
