At Toronto Pearson, am I completing Canadian arrival controls or US Preclearance?

Use the direction of the connection. Pearson says an international arrival connecting to a Canadian domestic flight goes through Canadian customs and immigration; US-bound departures use US Preclearance before boarding. These are different inspection processes. Enter the actual operating carriers in Pearson’s connection guide to obtain the route for your itinerary rather than treating every customs sign as interchangeable.

What this answer depends on

  • Toronto Pearson connection-stage identification; exact interactive itinerary route was not inspected
  • A Canadian domestic continuation after an international arrival involves Canada’s arrival process. A departure toward the United States involves the airport’s US preclearance process. The distinction matters when preparing documents and interpreting an app or declaration confirmation. This guide does not decide which permissions you personally need.
  • Pearson explicitly asks for the operating carrier when building connection instructions. A codeshare seller may differ from the company operating the flight. Read the “operated by” information on both legs before supplying the tool’s inputs; otherwise you can obtain instructions for the wrong airline arrangement.
  • Pearson says international arrivals connecting domestically in Canada complete Canadian customs and immigration.
  • Pearson describes US Preclearance before boarding US-bound departures.
  • Pearson’s connection guide instructs users to select the operating carrier.

Important exceptions

  • This research did not obtain a personalized result from Pearson’s interactive guide. No exact airside route, terminal, queue duration or admission guarantee is asserted. International-to-international combinations should not be inferred from the two examples above.

What to do next

  1. Identify the actual origin, onward destination and operating airline for each flight.

  2. Determine whether the relevant stage is Canadian arrival processing or US-bound preclearance.

  3. Use those operating-carrier inputs in Pearson’s current connection guide.

  4. Follow the resulting airport instructions and complete any remaining airline, border or security steps.

  5. Have both flight confirmations showing the operators, onward boarding pass and applicable travel documents.

Does a Canadian Advance Declaration complete US Preclearance?

No such equivalence is supported. Pearson describes Advance Declaration within the Canadian arrival process and US Preclearance as a separate US-bound procedure.
