Transportation of dangerous goods

The captain has authority to deny any vehicles that have leaks or are likely to leak (CFTR 151(9)).

If the captain suspects that a container contains dangerous goods that do not comply with transportation regulations, they can take all reasonable steps to confirm their suspicions and, if warranted, refuse to transport the container (CFTR 147).

Filling fuel tanks or transferring fuel on board is not allowed.

For safety reasons, there is no smoking on any of our ferries.

Transportation for personal use

You must turn off the ignition while you are on board and apply the parking brake (CFTR 151(1) c)).

A variety of products for personal use are permitted on board our ferries. Some of these products are subject to restrictions, as set out below.

We strongly recommend you fill gasoline, fuel, and propane containers AFTER the crossing.

Containers used to transport gasoline or any other fuel must comply with regulations.


If you are towing a trailer carrying a motorized boat or one or more motorized vehicles, you can only tow the maximum number permitted, i.e., one motor boat or a maximum of two motorcycles, all-terrain vehicles, snowmobiles, or jet skis.

Each boat or vehicle must be firmly secured to the trailer, and to prevent spills during the crossing, the fuel tank(s) must not be completely full.

Note: If you want to transport gasoline containers in addition to the boats and vehicles listed above, the fuel tank(s) of the boat or vehicle(s) being towed must be empty.
