• (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

(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
