It all depends as to where you are hunting. In some zones, all you need is a small game license, in others you will need a wolf tag. Once you shoot your wolf, you will need to pick up a permit at the nearest Ministry of Natural Resources (MNR), its a royalty the province collects, the cost is ridiculous, and will cost you about $1.50, yes a buck and a half.! This will allow you to take the pelt to a tannery, taxidermist or out of country. Without it you could face a heavy fine.
Best of luck, February was great wolf hunting in Ontario!
