I called Canada on Monday- as my passport expired this past November. I inquired as to whether or not I was still required to buy a RABC to fish the Canadian side of the rainy river. They told me that yes I still need it to fish their side. He mentioned that you don’t need it if you are only passing through while going from fishing spot a to spot b. That was my experience on Monday. I am not sure why there are so many mixed reports on whether or not it is needed. After I got off the phone, I sent in my application for the RABC, and I will buy the Ontario fishing license online as well.
If you haven’t dealt with Canadian border agents or immigration much than you might not be aware that it is very common to have very mixed answers to a single question or issue.
You’ve never needed a RABC or an Ontario fishing license to navigate on Canadian waters, so that part is technically incorrect. I’m guessing the person you talked to gave you the most conservative answer possible because they didn’t know the correct answer.
Here’s where you find that information.

If you enter Canadian waters, you are not required to present yourself and report your goods to the CBSA if you:
do not land on Canadian soil and do not anchor, moor or make contact with another conveyance while in Canadian waters;
do not embark or disembark people or goods in Canada.
