What are the Standard Height Requirements for Boat Transport?

In Ontario, boat transport must adhere to specific legal dimensions to ensure road safety and compliance with the Ministry of Transportation (MTO). The standard height and width requirements are:

  • Maximum Height: The total height of the boat while resting on the trailer must not exceed 4.15 meters (13.5 feet).
  • Maximum Width (Beam): The maximum allowable width without requiring special permits is 2.6 meters (8.5 feet).

When measuring your vessel, it is critical to include the highest point of the boat as it sits on the trailer. This measurement must account for all accessories, such as radar arches and even shrink wrap protection, as these can add several inches to the total height.

If your boat exceeds these standard dimensions, you are required to obtain an over-dimensional permit from the MTO before the move. For particularly wide vessels, additional safety measures, such as pilot cars, may also be legally required to ensure the route is clear.
