Frequently asked questions

Is 12 hours enough to leave Toronto Pearson International?
Yes. After immigration, transit and re-screening, you're left with about 7h in the city — enough for a real plan, not just a quick photo.
What can I do in Toronto in 12 hours?
With this window, favour what's close: CN Tower + St. Lawrence Market. Pick one area and stay in it rather than crossing the city.
When should I head back to the airport?
Keep at least 90 minutes to re-clear security and reach the gate, on top of the return journey. Better to wait at the lounge than to run.
Should I leave my luggage at the airport?
If it isn't checked through to your final destination, drop large bags at left-luggage before you head out. Travelling light on the airport rail keeps the whole plan faster.
Is it better to book a tour or go it alone in 12 hours?
With 12 hours, going it alone by airport rail is usually enough time for CN Tower + St. Lawrence Market without depending on a group schedule. An organized tour only makes sense if it includes a direct airport-to-airport transfer.
Updated: 2026 Rules change and depend on your exact ticket, airline and passport. Always confirm with your airline and the airport’s official immigration authority before you travel. IRCC — transiting through Canada ↗
