The requirement for boat operators to have proof of competency (a boat operators card) to operate a boat in Canada is only a few weeks away. As of Sept 15 this card is required to drive a fishing boat too. There is no grandfathering provision. I highly recommend that if you don't have the card that you get one in preparation of your next Ignace Outposts vacation.
Here are two sources of a card. It can be done on line. A Card issued in the US is valid in Canada.
