Commercial Tonnage Measurement Survey
Tonnage Measurement Survey for Commercial or Non-pleasure Purposes
A tonnage measurement is mandatory when registering a commercial vessel because it establishes the vessel’s official size and capacity. This measurement is not about weight, but rather about the internal volume of the vessel.
Reasons it’s required:
- Legal classification: Tonnage determines whether a vessel belongs in the Small Vessel Register or the Large Vessel Register.
- Regulatory compliance: Many Transport Canada rules, fees, and safety requirements are based on tonnage.
- Ownership and financing: A vessel’s tonnage must be recorded in the Canadian Register of Vessels to issue a valid certificate of registry, which serves as legal proof of ownership.
- International recognition: When sailing abroad, tonnage is part of the vessel’s official documentation under Canadian law, ensuring recognition and protection.
- Commercial use: For charters, workboats, or other non‑pleasure activities, tonnage measurement is essential to confirm the vessel meets commercial standards.
In short, tonnage measurement is the foundation of vessel registration. Without it, Transport Canada cannot issue a Certificate of Registry, and the vessel cannot legally operate in commercial service.
