I believe you only need a fishing license if you don't go to land(Pelee). If you go to Pelee, there is a phone booth (at least on the South side there was and I believe on the West side where the ferry's come in) where you can call in to report. I'd take your passport just in case but I plan on fishing Pelee for Walleye this weekend and don't plan to do anything except go fish (of course, I'll have my ontario fishing license)
