The Vessel Registration and Tonnage Regulations of the Canada Shipping Act 2001 (CSA 2001) cover vessel ownership, registration and tonnage measurement and their purpose is to prescribe certain obligations to owners of registered vessels including the requirements pertaining to tonnage. Tonnage measurement is mandatory for the purpose of registration.
Please refer to the following for details on:
Tonnage of vessels is determined in accordance with the Vessel Registration and Tonnage Regulations, TP 13430, either by using the Simplified Method of Tonnage Measurement [PDF Version] for monohull vessels, the Tonnage Measurement of a Simple Multihull Vessel [PDF Version] for simple multihull vessels or a duly appointed Tonnage Measurer.
If the vessel is to be measured by a Tonnage Measurer, you can either contact your Port of Registry or refer to Tonnage Measurements.
