Two events force a transporter to pick up the phone right away. If someone stops being crew while the vessel is in Canada, an officer at the nearest port of entry has to be told without delay, and the transporter has to record it and produce it on request. If someone came here to join the crew and never showed up inside the required window, that gets reported immediately too.
(1)A transporter must, without delay, notify an officer at the nearest port of entry of any foreign national who ceases to be a member of the crew for a reason listed in paragraph 3(1)(b). The transporter must record that information and provide it in writing on the request of the officer.
(2)A transporter must, without delay, notify an officer at the nearest port of entry when a foreign national who entered Canada to become a member of the crew of the transporter’s vessel fails to join the means of transportation within the period provided in paragraph 184(2)(b).
