At Toronto Pearson, immigration depends on where you are arriving from and where you are going next. Entering Canada, connecting to a Canadian flight and departing for the United States involve different processes. Prepare the correct travel permission first; then use Advance Declaration or an eligible US processing tool to simplify the relevant border stage. [1][2][3]

Canadian entry starts before you board

Your passport, citizenship, immigration status and method of travel determine the documents needed for Canada. A European residence permit, a US visa or an airline ticket does not by itself establish the right to enter. Use Immigration, Refugees and Citizenship Canada's official country-based guidance for the passport you will carry. [4]

Many visa-exempt foreign nationals need an electronic travel authorization, or eTA, when flying to Canada. Visa-required travellers generally need the relevant visa unless a specific exception applies. Canadian citizens and permanent residents have different documentary requirements; they should not apply the foreign-visitor instructions to themselves. [4]

The air-versus-land distinction matters on multi-country trips. A person who could enter Canada by road with a passport may still require an eTA when flying to Pearson. Conversely, holding an eTA does not turn a visa-required land arrival into an eligible one. The official eligibility tool is more reliable than extrapolating from a previous border crossing. [4]

Canadian permanent residents returning commercially generally need a valid PR card or permanent resident travel document. Most dual Canadian citizens need a Canadian passport for air travel, with specific arrangements for American-Canadian citizens. These are boarding-document issues, not problems that an expedited arrivals lane can solve. [4]

Prepare a concise account of the visit: where you are staying, how long you intend to remain and your onward arrangements. Keep booking information accessible offline. This is a practical preparation recommendation, not a claim that every passenger will be asked the same questions or must present the same supporting papers.

Arriving from overseas or the United States

An arrival from the US is an international arrival for Canadian purposes. Follow the signs for Canadian entry or your specific connection, rather than assuming that travel between the two countries has no border formalities. Pearson's arrivals guidance directs passengers to confirm identity and declare goods to the Canada Border Services Agency. [1]

Many passengers use a primary inspection kiosk or an eGate. The kiosk process involves scanning a travel document, taking a photograph and completing or confirming the declaration. The resulting receipt is then taken to an officer. Finishing the screen is not the same thing as completing every stage of admission. [1]

Kiosks are not appropriate for every traveller. Pearson identifies exceptions including non-machine-readable documents, certain documents other than a passport or Canadian PR card, and unaccompanied children under 16. Travellers in those categories are directed to in-person processing. Ask staff for the proper route instead of repeatedly trying an unsuitable machine. [1]

Be accurate about food, purchases and other goods. A declaration is not an invitation to guess what the officer would prefer to hear. When uncertain about an item, identify it and ask. The potential time saving from an app is secondary to making a truthful declaration.

Use Advance Declaration for the Canadian stage

Advance Declaration is an optional feature within ArriveCAN for participating airports, including Pearson Terminals 1 and 3. You can prepare the customs and immigration declaration within the 72 hours before arrival and use the relevant express lane where directed. It is not a visa, eTA or guarantee of admission. [5]

At the airport, scan your document, retrieve and review the declaration, correct anything that changed, and certify it. CBSA says an unconfirmed declaration expires after 72 hours, so a substantial delay can require a fresh submission. You still take the receipt for further processing. [6]

That detail makes the app useful even for careful planners: submitting earlier is not always better. Complete it within the actual arrival window, not weeks before departure while organizing the holiday. Keep your travel document information consistent with the passport being used.

NEXUS is a separate route. CBSA states that Advance Declaration cannot currently be used with NEXUS kiosks. Eligible travellers should follow the appropriate NEXUS or standard declaration process rather than assuming the two services stack into a single faster lane. [5]

A connection changes the route through the terminal

For an international arrival connecting to a domestic Canadian flight, Canadian border processing is part of the transfer. For an onward US flight, US border formalities may be involved. International-to-international transfers require attention to the airline, terminal, itinerary and permitted transfer route; there is no safe universal instruction to either collect every bag or bypass every border desk. [2]

Use the airline's connection instructions and confirm where checked baggage is tagged. A through-ticket does not justify ignoring signs, but separate tickets can add a landside collection and recheck process that a protected connection avoids. Ask the check-in agent to explain the bag's actual destination, not just whether the flights share an airline brand.

When booking independently, allow room for the steps you control least: a late inbound arrival, an immigration interview, baggage delivery and the next carrier's bag-drop cutoff. A connection that appears comfortable from landing time to departure time may be much tighter when measured against boarding and check-in deadlines.

There is no trustworthy single "Pearson immigration time" that works for every arrival. Citizenship, documents, passenger volumes and further inspection can change the experience. Do not convert an anecdote or a live queue snapshot into a guaranteed minimum connection time.

For a self-transfer that requires entering Canada, verify entry eligibility before buying the second ticket. Remaining within the airport building does not automatically mean remaining in an immigration-free transit zone. Where a transit exemption is relevant, confirm its exact conditions with the responsible authority and airline. [4][2]

US preclearance happens before departure

For US-bound flights using Pearson's preclearance facilities, you complete US customs and immigration in Toronto before boarding. This is distinct from CATSA security and from Canadian arrival processing. Allow time for both the security and American border stages. [3]

Pearson currently publishes US processing hours of 3:30 a.m.–9 p.m. in both terminals, with CATSA security beginning at 3 a.m. These hours describe the facility, not the last acceptable arrival for your flight. Airline check-in and boarding deadlines still apply. [3]

Mobile Passport Control, or MPC, is a free official US Customs and Border Protection app for eligible users. CBP's app description includes US citizens, lawful permanent residents, certain Canadian visitors and returning Visa Waiver Program travellers with approved ESTA. It does not make every foreign passport holder eligible, and it does not replace the physical passport or required US travel authorization. [7]

Pearson's instructions are to select the airport and terminal, complete the app's requested information at the appropriate stage, and present the receipt and passport to the officer. Do not submit as though you have landed at a US airport when you are actually using Canadian preclearance. Follow the app's location-specific prompts. [8]

NEXUS or Global Entry may provide a different eligible route. Likewise, assistance arrangements should be discussed with the airline and airport rather than interpreted as a purchasable immigration exemption. The officer, not a queue-booking service, decides admission.

Build one plan for the whole journey

The simplest preparation is to separate three questions. First, do you have the documents needed to board and enter or transit? Second, which border authority will process you at Pearson? Third, which optional tool fits that stage?

A visitor arriving from London for Toronto might need Canadian travel authorization and could use Advance Declaration. The same person's later flight from Toronto to New York involves US eligibility and preclearance, with MPC only if they qualify. The two apps do different jobs; neither covers the whole itinerary. [4][5][3][7]

Keep passports, essential medication and supporting bookings with you rather than in checked baggage. Leave appointment-free space immediately after a long-haul arrival, and avoid making an expensive non-refundable transfer depend on an assumed fifteen-minute border crossing. Good documentation and realistic buffers are more valuable than chasing a supposedly universal fast lane.
