Hmm, the only mammals that seemed to be in abundance were black bears, cougars and wolves, plus a few mice. Not sure if there are actually rabbits or deer on Vancouver Island? Or really any other kind of game commonly hunted for food? IIRC the contestants were not allowed to bring metal wire for snares, which would be a considerable handicap.

Given that the contestants were not particularly familiar with the local environment and had no access to truly effective weapons (eg. a high-powered rifle or shotgun) I am not surprised they had little luck as far as hunting.

I guess one could bring down a bear with a good bow, possibly a compound, maybe a very powerful longbow or recurve. But it would take some luck and a lot of guts no doubt. Not an easy thing to pull off if you're alone, hungry and exhausted. The participants were apparently very limited in the kind of archery equipment they could take. Most seemed to be carrying a 45 to 50lb recurve plus wooden arrows only. Insufficient for bear hunting IMO.
