4. For the purposes of subsection 60(4) of the Act, the prescribed period within which a person who acquires a vessel or a share in a vessel shall provide evidence that satisfies the Chief Registrar that the vessel is required or entitled to be registered under Part 2 of the Act is 30 days after the day on which the person acquires the vessel or the share.

5. The owner of a vessel previously registered in a foreign state but no longer registered in that state shall provide evidence in the form of an original or true copy of a written document, such as a deletion certificate or an abstract or transcript of registry, that establishes that the vessel is no longer registered in that state and that the foreign register records the vessel as being free and clear of all encumbrances.

6. In this Part, “length”, in respect of a vessel, means 96% of the total length on a waterline at 85% of the least moulded depth measured from the top of the keel, or the length from the fore side of the stem to the axis of the rudder stock on that waterline if that is greater. In vessels designed with a rake of keel, the waterline on which the length is measured shall be parallel to the designed waterline.

7. Every Canadian vessel that navigates in any waters and is subject to the 1969 Convention shall hold and keep on board an International Tonnage Certificate (1969).

• 8. (1) An International Tonnage Certificate (1969) held by a vessel that is transferred from the register of a state that is party to the 1969 Convention to the Register remains valid until the earlier of

  • (a) the day on which a period of three months after the day on which the vessel is registered in Canada expires, and

  • (b) the day on which the Minister issues a new International Tonnage Certificate (1969) to the vessel.

• (2) An International Tonnage Certificate (1969) held by a Canadian vessel ceases to be valid and shall be cancelled if an alteration resulting in an increase in the tonnage of the vessel, calculated in accordance with this Part, is made in

  • (a) the arrangement, construction, capacity or use of its spaces;

  • (b) the total number of passengers that it is permitted to carry, as indicated in its Passenger Ship Safety Certificate issued under the Vessel Certificates Regulations; or

  • (c) its assigned load line or permitted draught.

• (3) An International Tonnage Certificate (1969) held by a Canadian vessel remains valid and shall not be cancelled, and a new certificate shall not be issued before 12 months after the day on which the current certificate is issued, if a decrease in the net tonnage of the vessel, calculated in accordance with this Part, results from an alteration in

  • (a) the arrangement, construction, capacity or use of its spaces;

  • (b) the total number of passengers that it is permitted to carry, as indicated in its Passenger Ship Safety Certificate issued under the Vessel Certificates Regulations; or

  • (c) the trade in which the vessel is engaged, if the alteration changes its assigned load line.

• (4) Subsection (3) does not apply in respect of a vessel that

  • (a) is transferred to the flag of another state;

  • (b) undergoes substantial alterations, such as the removal of a superstructure, that require a change of its assigned load line; or

  • (c) is a passenger vessel that is engaged in the carriage of large numbers of unberthed passengers in a special trade such as the pilgrim trade.

• (5) If an International Tonnage Certificate (1969) held by a Canadian vessel is cancelled because of a change in tonnage resulting from an alteration referred to in subsection (2) or (3), the tonnage corresponding to the new characteristics of the vessel shall be calculated in accordance with this Part and, subject to subsection (3), the Minister shall issue a new International Tonnage Certificate (1969) to the vessel in the form set out in Annex II of the 1969 Convention.
