I have a problem with this! This law, if past covers all motorized vehicles won't it? Can't have a few beers fishing in a boat or at the beach if you plan to drive your boat home. I'm assuming.

Alcohol and Boats Have your Beer on the Pier
Red Cross statistics: Boating and Alcohol
37% of boaters in Canada admit to consuming alcohol every time they boat.
66% report they drink alcohol sometimes when boating.
Alcohol is a factor in over 40% of recreational boating fatalities.
The Red Cross claims that up to 200 Canadians will drown this year as a result of boating-related incidents, and 25% of those will have alcohol in their blood. Many other incidents involving even serious injuries are not reported.
In all provinces of Canada, operating a boat while under the influence of alcohol is illegal. In some provinces, no one on board can consume alcoholic beverages while the boat is being operated. In provinces like Ontario, you can't even transport alcohol unless the boat is classed as a "home" with sleeping accommodations and a head. There are differences between provinces, but all require alcohol on board to be packaged and out of reach. Even then, when you visit shore or even on board your own boat, Ontario law says you must not "display alcohol to the public". Alcohol consumed at a public picnic table is usually illegal. If you are visiting a marina, you should check to see to make sure it's a "private club", not a public place, before drinking at a picnic table on shore.
Impaired Boating (Transport Canada Aug/2005):
Boating while impaired is an offence under the Criminal Code of Canada. The laws are enforced by local, provincial and federal police who carry alcohol-screening devices on the water.
Upon conviction for the offence of impaired operation of a vessel, or of operating a vessel with more than 80 milligrams of alcohol per 100 millilitres of blood, a person is liable of the following:
1st offence - a minimum fine of $600
2nd offence - imprisonment for not less than 14 days
3rd and each subsequent offence - the maximum sentence for these offences may vary depending on provincial statutes.
Transporting Alcohol (Alcohol and Gaming Commission of Ontario):
Under what circumstances is it illegal to transport beverage alcohol?
It is illegal to transport beverage alcohol in a motor vehicle, a motorized snow vehicle or a boat unless the beverage alcohol is in a container that is unopened and the seal unbroken, or unless the beverage alcohol is packaged in baggage that is fastened closed or is not otherwise readily available to anyone in the vehicle. In a boat, the beverage alcohol must be stored in a closed compartment.
What boats may carry alcohol (Ontario Liquor Laws Sec.3/7):
A boat with permanent sleeping accommodations and permanent cooking and sanitary facilities, other than a boat used to carry passengers for hire, is considered to be a private place while the boat is at anchor or is secured to the dock or land. ...
