Your canoe should be fine in the canal, but I wouldn't take it out into the bay.
I had the best success at night casting and reeling through the submerged lights, from a kayak. You'll see the fish in the lights if they are there. Glow swim bait (charge it with a head lamp), chrome rattle trap, mirro-lure. They were picky about the lure and retrieval speed. Fast worked better than slow. I paddled up and down the entire canal system and at the end of the week caught almost as many from our own dock, but the kayaking was more fun.
Live shrimp would be best, either free lined or under a popping cork, but they can be a pain to find, bring with you, and keep alive.
