Quick summary: Terminal 1 vs Terminal 3 at Pearson

In short: Terminal 1 is the newer, larger “hub” terminal at Toronto Pearson, home to many major international and domestic carriers and most airline alliances’ operations. Terminal 3 is an older terminal that still handles many flights (including some domestic and international carriers and low-cost airlines). Both terminals provide essential services (check-in, security, customs), but they differ in size, layout, airline allocations, and some transport links. Always check your airline’s terminal and the official Toronto Pearson site for the latest information before travel.

Why this matters

Understanding the differences between Terminal 1 and Terminal 3 can save you time, reduce stress, and help you plan transfers, parking, and transit. A wrong assumption about which terminal your flight uses can result in missed flights or long connection times, especially at busy periods.

Detailed differences: layout, airlines and operations

Terminal 1 — overview

Terminal 1 is the larger, newer terminal complex at Pearson, opened as a consolidated modern international terminal. It features a centralized check-in hall, extensive security screening capacity, numerous gates with jet bridges, and most of the airport’s international arrivals and departures operations for major carriers. Terminal 1 is commonly the primary terminal for the national carrier and many Star Alliance members, as well as other global airlines.

Terminal 3 — overview

Terminal 3 is older and smaller than Terminal 1 but remains critically important to Pearson’s operations. It handles a mix of domestic and international flights and is often used by low-cost carriers and some full-service airlines. Terminal 3 has its own check-in and security facilities and a range of shops and dining options.

Which airlines use each terminal?

Airline terminals can change due to scheduling and operational needs. Generally:

Terminal 1: Many international carriers and large network carriers use Terminal 1. Historically, this includes Air Canada as a major operator as well as many Star Alliance partners and other global airlines.
Terminal 3: Often used by WestJet and several low-cost carriers, plus airlines that have maintained operations in the older terminal.

Tip: Always confirm the terminal for your flight on your ticket, the airline’s website, or the official Toronto Pearson flight status page before travel.

Check-in, baggage, and security differences

Check-in counters

Terminal 1’s check-in hall is larger and often more centralized with numerous kiosks and airline counters. Terminal 3 has a smaller, more compact check-in area which can be quicker if your airline is based there and queues are short.

Baggage drop and handling

Because Terminal 1 handles a higher volume of international traffic, baggage processing capacity is substantial. If you have connecting flights between T1 and T3 and checked luggage, confirm whether your airline will transfer bags automatically or if you must claim and re-check them — some interline connections require re-checking at the gate or baggage claim.

Security screening

Both terminals have modern security facilities, but wait times vary by time of day and season. Terminal 1 tends to be busier during peak international departure windows. Use the airline’s online check-in and consider trusted traveler programs (e.g., NEXUS) where applicable to reduce wait times.

Customs, immigration and U.S. preclearance

Pearson has Canadian customs and immigration facilities in arrivals areas for both terminals. One of Toronto Pearson’s advantages is the U.S. preclearance facility, which allows passengers to clear U.S. Customs and Border Protection before departure — enabling arrival in the U.S. as a domestic flight at the destination.

Whether U.S. preclearance operates in Terminal 1, Terminal 3, or both can change with airline schedules and facility allocations. Verify the location of U.S. preclearance for your specific flight on the airline’s site or Toronto Pearson’s official pages.

Transfers between Terminal 1 and Terminal 3

Transferring between T1 and T3 is a common need for connecting passengers. Here’s how to plan:

Allow extra time: Give yourself at least 30–60 minutes for a connecting transfer, more during peak times or if you must clear immigration and re-check bags.
Terminal Link options: Pearson provides free inter-terminal connections via shuttle services or dedicated transfer systems. Check the official site for the latest transfer options and schedules.
Ground-level transit: For short walks or shuttle buses, follow the airport signage. Luggage and mobility limitations may make shuttles preferable.

Ground transportation: UP Express, taxis, rideshares and parking

UP Express (train to downtown Toronto)

UP Express provides fast rail service between Toronto Pearson and Union Station downtown. The UP Express station serves Terminal 1 directly; if you are in Terminal 3, allow a short transfer to Terminal 1 to access the train.

Taxis and rideshares

Designated pick-up and drop-off points are posted for both terminals. Rideshare services (Uber, Lyft) typically have specified staging areas; follow the airport’s directions to the official pickup points to avoid fines or delays.

Parking

Short-term and long-term parking areas serve both terminals. Terminal 1 has close proximity parking garages and walkways; Terminal 3 parking areas are nearby but may require a short shuttle or walk. Use official parking maps to choose the best lot for your needs.

Amenities and passenger experience: lounges, shops and dining

Lounges

Terminal 1 usually hosts more premium and alliance lounges due to its higher volume of international passengers and alliance hubs. Terminal 3 has lounges too, but fewer in number. If lounge access is important (priority pass, airline status, paid access), check the terminal map for lounge locations and entry requirements.

Shops and dining

Both terminals offer a good mix of shops and restaurants, but Terminal 1 has a broader selection and more international-brand stores and dining options given its size. Terminal 3 can be more compact but still provides essentials and pleasant dining choices for travelers.

Accessibility and family services

Both terminals provide accessibility services: wheelchair assistance, family washrooms, nursing rooms, and accessible facilities. Request special assistance through your airline in advance to ensure staff meet you at the correct terminal and gate.

Common traveler scenarios and practical advice

Arriving into T1 and connecting to a T3 flight

Check whether your inbound flight arrives lands at an international or domestic gate and if you’ll need to clear customs and immigration. This affects your transfer time.
If you have checked luggage, confirm whether it will be transferred automatically. If not, allow time to collect and re-check.
Use the free terminal transfer service and allow at least 45–90 minutes for the transfer depending on time of day and customs requirements.

Arriving in T3 and departing from T1

Follow the same steps in reverse. Note that some transport options (like UP Express) are located at Terminal 1, so plan transit time accordingly.

Late-night flights and short connections

Late at night, services and shuttles may run less frequently. If you have a short overnight connection, contact your airline and the airport in advance to confirm transfer options and timings.

Tips to avoid problems

Always verify terminal and gate: Flight gates can change — check the airline’s app and airport monitors.
Allow extra time: For inter-terminal transfers, customs, or baggage re-checking, allow more time than you’d normally expect.
Download airline and Toronto Pearson apps: They provide up-to-date gate, terminal, and transfer information and can send alerts about changes.
Use online check-in and e-boarding passes: Reduces wait time at counters.
Enroll in trusted traveler programs: Programs like NEXUS can speed immigration and security screening.

Examples of planning for specific traveler types

Business traveler connecting internationally

Recommended: Fly into Terminal 1 where alliance lounges and business facilities are concentrated. If your onward flight departs from Terminal 3, request a minimum connection time from your airline and use premium transfer services where available.

Family traveling with young children

Choose direct flights within the same terminal where possible, or leave a large buffer for transfers. Both terminals have family facilities, but Terminal 1’s larger space may be easier for stroller handling and finding family-friendly dining.

Passengers with reduced mobility

Book assistance in advance with your airline. Terminal 1 features extensive accessibility options; let the airline know if you will need an inter-terminal transfer so staff can meet you at the right place.

How to find up-to-date terminal assignments

Check your flight confirmation and boarding pass — it usually lists the terminal.
Visit the airline’s official website or app for terminal and gate updates.
Use the Toronto Pearson official flight status tool: Pearson Flight Status.
On arrival at the airport, monitor the flight information displays for terminal and gate changes.

Security, customs and documentation checklist

Valid passport and visa (if required).
Boarding pass and flight confirmation.
Any customs forms or declarations (for certain countries and goods).
Proof of onward travel or accommodation if requested by immigration.
Special documentation for pets or medical supplies if applicable.
