Toronto Layover Guide: What a Pearson (YYZ) Long Layover Actually Lets You Do
Rules on this page last verified 2026-07-09. Airlines change things; we re-check and date it.
You've got a connection through Toronto Pearson (YYZ) and you're trying to figure out if it's worth leaving the airport. Good news: entry is easy on a US passport. The part nobody tells you is that Pearson's own lines, not the border, are what eat your clock, especially on the way back into the US.
The short version
| Entry for US passport holders | No visa, no eTA. Valid US passport required for air travel (passport card/NEXUS alone won't work by air) |
|---|---|
| Downtown transit | UP Express train, Pearson to Union Station, 25-28 min, $12.35 one-way ($9.25 with PRESTO) |
| Minimum layover to leave airport safely | 8 hours, and that's tight round-trip on domestic-to-domestic; budget more if your return flight is to the US |
| The real time cost | US preclearance at Pearson happens before you board, not after you land in the US, plan 2.5-3 hours before a US-bound flight |
| Luggage storage | Radical Storage near Union Station, ~C$8/day/bag, no airport-side lockers inside Pearson terminals for transit passengers |
| What Air Canada offers if you fly through here | A Toronto stopover program exists on Air Canada tickets to Europe/Asia (terms vary by source, verify before booking) plus a flat 5,000-Aeroplan-point stopover add-on for award tickets |
Getting in: US passport entry to Canada
If you're a US citizen, Canada is about as simple as international entry gets. No visa, no eTA, no advance authorization needed for air travel, just a valid US passport. The catch for flyers specifically: for air travel you need the actual passport book. A passport card, NEXUS card, or enhanced driver's license won't get you through the airport, even though they work at land and sea crossings.
Your passport only needs to be valid on your entry date, Canada doesn't have the "6 months remaining" rule some countries enforce. You can optionally file an Advance CBSA Declaration up to 72 hours before arrival to speed through the kiosk step, but it's not required.
Border officers do have discretion over how long they let you stay and what questions they ask, so have a rough plan for your hours in the city ready if asked.
How long you actually need
This is where Pearson differs from a lot of "easy" countries. The border rules are simple. The airport's own processing is not always fast.
- Landing and getting through Canadian immigration: self-serve kiosks scan your passport and customs declaration, then you queue again for an officer to direct you onward. Budget 20-45 minutes in normal conditions, more during the 12pm-6pm peak landing window.
- Getting downtown and back: the UP Express covers Pearson to Union Station in under 30 minutes, so transit itself isn't the bottleneck.
- Getting back through security for your onward flight: if your next flight is to the US, you clear US preclearance at Pearson before boarding, not on arrival stateside. Toronto Pearson's own guidance is to arrive at least 2.5-3 hours before a US-bound departure, more during peak periods, and USCBP processing at Pearson only runs 3:30am-9pm.
Put together: a genuine "leave the airport and come back" layover needs at least 8 hours if you're flying domestic-to-domestic, and closer to 10-12 if your outbound flight is US-bound, because that preclearance line is a hard floor, not a suggestion.
What fits at each layover length
5 hours: stay in the terminal loop, or don't try. By the time you clear immigration, ride the train in, and ride back for a US-bound preclearance line, 5 hours is spent. This window is for the airport itself, not the city.
8-12 hours: one real neighborhood, done properly. Clear immigration, UP Express to Union Station (25 min), and you have roughly 4-6 hours in the city depending on your return flight's destination. That's enough for St. Lawrence Market (closed Mondays, otherwise open daily) plus a walk through the Distillery District, or the CN Tower observation deck if you'd rather do one big-ticket thing. Store bags at Radical Storage near Union Station rather than dragging them around.
24 hours: CN Tower, market, and a real dinner. A full day lets you combine St. Lawrence Market in the morning (it's a working market, go early), the Distillery District's pedestrian-only cobblestone streets in the afternoon, and the CN Tower at golden hour before heading back for your evening flight. This is also the range where Air Canada's own Toronto stopover programs start to make sense, since they're built around multi-day stays, not a few hours.
What's free and what's not
Free: entering Canada itself for US passport holders, browsing St. Lawrence Market and walking the Distillery District. Paid: the UP Express train ($12.35 one-way, cheaper with PRESTO), luggage storage (~C$8/day), CN Tower admission, and any Air Canada stopover hotel package if you extend past a same-day layover.
Where people screw this up
- Timing the return around Canadian rules instead of US preclearance. The Canadian border is fast and simple. The US preclearance line at Pearson before a US-bound flight is the actual constraint, and it has fixed hours (3:30am-9pm).
- Bringing a passport card instead of the book. Works at land crossings, not for flying.
- Assuming the CN Tower and Distillery District are close together. They're both worth doing, but pick one as your anchor per layover length rather than rushing both on a short window.
- Not checking St. Lawrence Market's Monday closure. Show up on the wrong day and the whole plan collapses.
FAQ
Do I need an eTA to layover in Toronto on a US passport? No. US citizens are exempt from Canada's eTA requirement for air travel; a valid US passport is sufficient.
Is 5 hours enough to leave Pearson? Technically possible if everything runs on time, but not recommended, especially if your onward flight requires US preclearance. Treat 8 hours as the practical floor.
Does Air Canada actually give a free Toronto stopover? Air Canada has run Toronto stopover offers for tickets connecting to Europe or Asia, letting you break your trip in the city at no extra airfare. The exact length (reported anywhere from 48 hours to 7 days depending on the offer) and eligible routes change, so check the current terms on aircanada.com before you book, not a blog post.
Next time, plan this on purpose
If you're already committed to this connection, the honest read is: entry is the easy part, timing is the hard part. But Toronto isn't just a place to survive a layover, Air Canada's own stopover program and Aeroplan's flat 5,000-point stopover add-on exist specifically so a Canada connection becomes a second trip instead of dead time. If you haven't booked yet, or you're booking your next one, see how points and stopover rules actually stack across airlines in how points stopovers work.
