I'll bet you that there isn't a lawyer in Ontario that would know the answer to the question the OP posed. I'd contact a CO like blasted_saber pointed out and be real CLEAR on your scenario.Is anyone here a lawyer? Then these are all just educated guesses. Regardless, they could still be charged just to be acquitted later. Don't ask the internet for legal advice.
With that said, it sure sounds like a grey area. If the hunter is not killing deer for 'gain', what case would Crown have?
I went through the Set Fines (17.5 - 17.10) to see if there was anything that might jump out as far as being illegal, nothing.
