Boating in Ontario’s stunning waterways is a favorite pastime for many. But just like driving, operating a vessel while impaired by alcohol or drugs is a serious offense. Boating Under the Influence (BUI) laws in Ontario align closely with impaired driving laws under the Criminal Code of Canada, and penalties can be just as severe. In this article, we’ll break down everything you need to know about BUI in Ontario — from legal limits to penalties and safety tips — ensuring you stay safe and compliant on the water.
BUI occurs when a person operates a watercraft while impaired by alcohol, drugs (including cannabis), or both. The laws are enforced by both the Ontario Provincial Police (OPP) and other maritime enforcement bodies.
CategoryLegal Limit
Fully Licensed BoaterUnder 80 mg of alcohol per 100 ml of blood
Zero Tolerance (e.g., youth, commercial)0.00% BAC
Drug ImpairmentAny detectable amount if impaired judgment is observed
If you're caught over the legal limit or under the influence of drugs, you're subject to the same criminal charges as if you were driving a car under the influence.
Ontario takes BUI very seriously, and the consequences can be life-altering.
