From what I understand, the factor to consider isn't necessarily the size of the water body. It's more a question of how far the boat is from the shore. So even on a large body of water, if the boat passes close to the shore, there will still be an effect on the shore.
There's something else I'd like to discuss with you. Right now, each municipality or local government seeking to regulate a waterway has to apply for that particular waterway.
Do you think it would be more effective or preferable to have some type of basic universal regulation, based on science, so that we don't have to apply for every one of the thousands of lakes in Quebec, for example? Right now, municipalities have to submit one application after another to Transport Canada to solve the problems they're experiencing with waterways in their area.
