What should you do if the arrival time changes by 15 minutes?

When the arrival time changes by 15 minutes, notifying CANPASS immediately is important because this system plays a crucial role in managing and facilitating the entry of international flights into Canadian airspace. CANPASS, which is part of Canada's customs and immigration program, must be kept informed of any changes to an aircraft’s schedule, especially when they fall outside of planned timelines.

Fulfilling this requirement helps ensure compliance with regulatory obligations and avoids potential non-compliance issues that could arise from miscommunication about the flight's schedule. This is especially critical for operations under Part 135, where adherence to regulations and proper communication with customs is necessary for the operation of on-demand passenger services.

In this context, other responses do not align with standard operating procedures. Proceeding without notification could result in penalties or delays upon arrival, canceling the flight is an excessive response to a mere schedule change, and notifying the nearest control tower, while important in other situations, does not directly address the requirement for customs notification in this case.
