Toronto Pearson (YYZ) Minimum Connection Time in 2026: Why the Floor Is 120 Minutes

Toronto Pearson publishes the most intimidating connection floor of any airport in our coverage: the OAG standard minimum connection time at YYZ is 120 minutes, for every connection type. Domestic to domestic: 120. International to international: 120. There is no published case below two hours (OAG MCT database via ExpertFlyer, verified May 29, 2026).

That number is honest about Pearson’s worst case and wildly pessimistic about its best case, and the gap between the two is the entire story of connecting at YYZ. The same OAG database carries Air Canada’s filed exceptions at its Terminal 1 hub: 70 minutes domestic, 60 minutes domestic-to-international, 75 minutes off an international arrival, roughly half the airport standard. Which number applies to you depends on three things: whether both flights are Air Canada (or its Star Alliance partners under one ticket), whether your route crosses one of the two borders that operate inside this airport, and whether you have to change terminals on a train that sits outside security.

Quick reference: published minimums vs realistic padding

Published values are the airport-standard and carrier-filed OAG minimums (ExpertFlyer, verified 2026-05-29). The right-hand column is our editorial padding recommendation, not an official figure.

Why is Pearson’s published floor 120 minutes?

Because the airport-standard MCT has to cover the interline worst case, and Pearson’s worst case stacks three slow layers on top of each other:

1. A border crossing on arrival. Per the airport’s official guidance, you clear Canadian customs and immigration whenever your flight into Pearson is international (including from the US) and your flight out is domestic. That is kiosk processing, possibly a bag pickup, and a queue whose length you do not control.
2. A landside terminal change. Terminal 1 and Terminal 3 are connected by the free Terminal Link train, which runs 24 hours with a 4-to-8-minute maximum wait. But it boards outside security, so an interline transfer between terminals means exit, ride, and a full re-screen.
3. A second country’s border on departure. Pearson is a US preclearance airport: travelers to the US clear US customs and immigration before boarding, at Pearson. Great for arrival in the US; one more checkpoint before a US-bound departure.

An Air Canada-to-Air Canada connection inside Terminal 1 touches none of the three, which is why AC’s filed minimums are nearly half the standard. The published 120 is what happens when an itinerary touches all of them.

The two borders inside one airport

YYZ is one of the few hubs where you can clear two countries’ border controls in a single connection.

Inbound, Canada (CBSA). International arrivals confirm identity and declare goods at a primary inspection kiosk: scan your passport, take a photo, answer the declaration questions, and bring the receipt to an officer. Up to five travelers living in the same country can use a kiosk together. NEXUS members get dedicated kiosks. The genuinely useful hack is Advance Declaration in the ArriveCAN app: submit your declaration up to 72 hours before landing and use the dedicated Express Lanes on arrival, which the airport explicitly encourages.

Outbound, United States (CBP preclearance). If your departing flight is to the US, you clear US customs and immigration at Pearson before boarding, and land in the US as a domestic arrival. NEXUS cardholders and priority-access passengers get a dedicated line. For connection math, treat a US-bound departure as security plus a second border queue.

The four connection cases at YYZ

Case 1: Air Canada (or Star Alliance) to Air Canada, Terminal 1, one ticket. The fast case the 120-minute standard hides. Bags through-checked, no terminal change, and depending on the routing little or no border processing before your onward gate. AC’s filed floor is 60-75 minutes; we pad to 75-90 by choice, more if you land at a far gate.

Case 2: International arrival, domestic departure. The case the official guidance singles out: CBSA processing, then per the airport’s baggage rules you may need to collect your bag and place it on the connection drop-off belt even when it is tagged through, then re-clear security. With Advance Declaration filed and a single ticket, 2 hours is workable; 2.5 hours is comfortable; less than 90 minutes is gambling.

Case 3: Connecting onto a US-bound flight. Everything in your inbound case, plus the preclearance queue. From a domestic arrival in T1 onto an AC flight to the US, 2 hours is usually fine. From an international arrival, you are crossing two borders in one building: pad 2.5 to 3 hours.

Case 4: Anything crossing T1 and T3. Air Canada and Star Alliance live in Terminal 1; WestJet, American, Delta, British Airways, Air France, KLM, Emirates, Qatar Airways, Japan Airlines, Cathay Pacific, and Korean Air operate from Terminal 3. An itinerary mixing those groups changes terminals on the landside LINK train with a full re-screen, and if it is two separate tickets, with a landside bag re-check and your second airline’s check-in deadline. Treat 2.5 to 3 hours as the sensible minimum.

Terminal 1 vs Terminal 3

The practical rule: keep a connecting itinerary inside one alliance family and you will almost always stay inside one terminal. The moment a booking site hands you an Air Canada arrival and a WestJet departure, you have bought a terminal change plus re-screening, and the price had better reflect it.

Do I need an eTA just to connect?

Probably, and this is the most commonly missed YYZ-specific rule. Per Immigration, Refugees and Citizenship Canada (verified June 10, 2026):

• Travelers from eTA-required countries need an eTA to transit through Canada by air, even without leaving the airport.
• Travelers from visa-required countries need a transit visa for connections between international flights of 48 hours or less.
• US citizens and US lawful permanent residents transit without a visa, with the right travel documents.
• Passport holders from China, Indonesia, the Philippines, Thailand, and Taiwan may qualify for transit-without-visa programs under specific conditions.

Airlines verify this at check-in for the first leg. An otherwise perfect connection plan dies at origin if the transit document is missing, so sort it out when you book, not the week you fly.

What if I’m on separate tickets at YYZ?

Separate tickets remove every safety net at once: no through-checked bags, no rebooking obligation if the first flight is late, and a connection that becomes a full arrival plus a full departure. At Pearson that means baggage reclaim (after CBSA, if arriving international), landside transit (possibly the LINK train), check-in against your second airline’s cutoff, security, and preclearance if the second flight is US-bound. Give a separate-ticket connection at YYZ a minimum of 3 hours domestic and 4 hours if either leg is international or US-bound, and remember most non-US passport holders need the eTA regardless.

How Toronto Pearson compares to other major hubs

The honest comparison: YYZ’s published floor is the scariest on this table, but its behavior is closer to Frankfurt than to Heathrow. A single-alliance, single-terminal connection is genuinely efficient; the airport only earns its 120-minute reputation when an itinerary stacks borders and terminals.

When to add even more padding

• Winter. Toronto de-icing season compresses departure banks and cascades delays; add 30-60 minutes to any December-to-March connection you care about.
• Summer peak evenings. Transatlantic banks land in waves; CBSA and preclearance queues stretch at peak. Typical security waits run roughly 10 minutes off-peak and 30 at peak.
• First entry with a new eTA or a first-time NEXUS-less arrival. Kiosk plus officer processing is fast when it is fast; budget for when it is not.
• Last flight of the day onward. If the onward flight is the day’s last to your destination, ignore every minimum above and book the longer option.

The verdict

Pearson is two airports wearing one code. Inside Terminal 1 on Air Canada paper, it is one of the easier major hubs in North America: a 60-75 minute filed floor that mostly holds, with bags through-checked and no train ride. Across terminals, across tickets, or across either of its two borders, it is a 2.5-to-3-hour airport, and the 120-minute published standard is the warning label saying so. Decide which Pearson you are flying through before you let a booking engine decide for you.
