A 12-hour layover is a strange limbo: far too long to suffer on a hard terminal chair, but it can feel daunting to navigate a new country in half a day. Do not resign yourself to overpriced airport Wi-Fi and boredom just yet.
We have run the numbers and this is a definitive Green Light. You CAN and should leave the airport. After clearing customs at YYZ, the logistics confirm you will have exactly 8 hrs 25 mins to explore Toronto before you need to head back for your next flight.

The “Speed Run” Itinerary: What to Do in 8 hrs 25 mins
You have a Green Light. This means you have enough buffer to take the UP Express into the city and enjoy the downtown core without constantly checking your watch.
Step 1: Drop Bags
Head immediately to Excess Baggage (T1 & T3 Arrivals). Dragging luggage through downtown Toronto is a nightmare; pay the fee and travel light.
Step 2: The Train
Follow signs for the “Train to City” and board the UP Express. Take it all the way to the terminus: Union Station. It is fast, reliable, and immune to Toronto’s notorious traffic.
Step 3: The Icon
Exit Union Station and walk the SkyWalk or streets to the CN Tower (Base/Glass Floor). You have plenty of time to go up, but even standing at the base looking up is impressive. Snap the proof-of-travel photo.
Step 4: The Sea Life
Right next to the tower is Ripley’s Aquarium. It is a fantastic loop that fits perfectly into this itinerary. Stroll through the shark tunnel—it’s surprisingly relaxing after a long flight.
Step 5: The Refuel
Walk back into the transit hub and grab a meal at Union Chicken (Inside Station). It is convenient, delicious, and ensures you are already at the station for your departure.
Step 6: The Return
Head back to the UP Express platform. Do not push your luck; aim to be on a train that gets you back to YYZ at least 2 hours before your flight departs.

Transit Guide: YYZ to Toronto
Primary Option: UP Express
This is your best friend. It departs from Terminal 1 every 15 minutes (check current schedules) and takes only 25 minutes to reach Union Station.
Secondary Option: Uber / Lyft
Rideshare is available, but be warned: Traffic in Toronto is unpredictable and often brutal. A car takes 30 – 60 Mins and costs CAD 60 – 80 one-way.
Verdict: Only take a car if you have heavy luggage you couldn’t store, or if the trains are down. With 12 hours, you can risk traffic, but the train is strictly superior for stress management.
