The simplest answer: install a Canada eSIM before you land at Toronto Pearson. You skip the hunt for a counter, you have working data the instant your plane touches down, and you avoid paying Canada's notoriously high prices for an airport SIM. Pearson has electronics shops and kiosks in Terminal 1 and Terminal 3 where you can buy a local prepaid SIM, plus free WiFi throughout, but all of those still mean stopping, configuring, and overpaying while jet-lagged. A travel eSIM activates over WiFi or home data in a couple of minutes and is ready before wheels-down.

SIM and eSIM Options at Toronto Pearson
Toronto Pearson has two passenger terminals, Terminal 1 and Terminal 3, connected by a free automated LINK train. Connectivity options are not spread evenly across them, and Canada has no tradition of dedicated airport SIM counters the way some Asian hubs do. Here is where to look once you clear customs.
Quick Terminal Summary
Terminal 1: the larger terminal, home to Air Canada and Star Alliance partners, with electronics and convenience shops plus some prepaid SIM kiosks airside and in arrivals. Terminal 3: serves WestJet, Air Transat, and many international carriers, also with convenience and electronics retail. Neither terminal has a high-profile staffed SIM desk like Tokyo or Bangkok; you are buying from a general retailer or a vending kiosk, or you simply activate an eSIM.
Prepaid SIM at Retail
Shops in both terminals sell prepaid Canadian SIM cards from carriers and resellers such as Rogers-owned brands and Public Mobile. The catch is the price. Canadian prepaid data is expensive to begin with, and the airport markup makes a short-stay tourist SIM poor value. You will often pay far more than an online eSIM for the same data, and you may need to spend time on activation.
eSIM on the Spot
There is no need to buy a physical SIM at all. Connect to the free Toronto Pearson Public Wi-Fi, buy a Canada eSIM online, and install it in a few minutes. That is the exact same thing you could have done at home, which is why pre-installing before departure is the cleanest path of all. If you land late at night when shops are shut, the eSIM route works regardless, with no counter hours to worry about.
Free Airport WiFi at Pearson (Toronto Pearson Public Wi-Fi)
Pearson offers genuinely good free WiFi across both terminals, which matters because it is what lets you activate an eSIM or buy a plan online the second you arrive.
Open WiFi settings
On your phone's WiFi screen, look for the network named Toronto Pearson Public Wi-Fi. No password is required. The exact SSID can change, so if you do not see it, pick the network that clearly references the airport.
Accept the terms
A landing page appears. Agree to the terms and conditions and tap to connect. When the WiFi icon shows a connection, you are online.
Use it anywhere in the terminal
The free WiFi covers both Terminal 1 and Terminal 3, including arrivals, gates, and baggage claim, and it runs around the clock with no time limit. It is the easiest way to confirm your eSIM is live before you head downtown.
Why the free WiFi is not enough on its own
Airport WiFi stops at the terminal door. The moment you board the UP Express or step outside to a taxi, you lose it, and public WiFi is slower and less secure than a dedicated mobile data plan. Treat Toronto Pearson Public Wi-Fi as the tool you use to confirm your eSIM is working, not as your connection for the trip.
Pearson to Downtown Toronto: Transit and Data En Route
Pearson sits about 22 km northwest of downtown Toronto, so the ride into the city is a real trip. This is precisely the stretch where you want working mobile data: to navigate, to message your accommodation, and to plan your first stop. Here are the three main options.
| Option | Destination | Time | Fare (one way) |
|---|---|---|---|
| UP Express train | Union Station (downtown), via Bloor and Weston | About 25 to 28 min | $12.35 adult, or $9.25 with PRESTO |
| TTC bus + subway | Kipling or Lawrence West station, then the subway downtown | 60 to 90+ min | $3.35 single TTC fare (PRESTO) |
| Taxi / rideshare | Door to door, anywhere in the city | 30 to 60 min (traffic dependent) | Roughly $60 to $75 to downtown |
The UP Express is the standout choice for most visitors: it leaves from Terminal 1 (Terminal 3 passengers ride the free LINK train over first), runs every 15 minutes, and reaches Union Station in the heart of downtown in about 25 to 28 minutes. The adult fare is $12.35, dropping to $9.25 if you tap a PRESTO card. The TTC route via the 900 Airport Express bus is the cheapest at a single $3.35 fare but is much slower with transfers. A taxi or rideshare is the most flexible if you have heavy bags or arrive very late.
Data coverage on the ride in
The UP Express advertises free onboard WiFi, but as with most train WiFi it can be slow and patchy at busy times. Cellular data from your own eSIM is far more reliable across the route: Toronto's networks blanket the line into Union Station, so with your own plan you stay connected for maps, transit transfers, and messages the whole way in, which is exactly when you need it most.
Why Install an eSIM Before You Land
There is a clear case for sorting your connection before the plane even pushes back from your home airport, and in Canada the price argument is especially strong.

How to do it
Buy a Canada eSIM online a day or two before you fly, install the profile while you still have home internet, then leave it switched off until you arrive. When you land at Pearson, flip the eSIM line on in your settings and you are connected immediately, with no need to log in to Toronto Pearson Public Wi-Fi.

Pearson SIM Prices vs an eSIM
Here is the money question, and in Canada it lands harder than almost anywhere. Canadian prepaid data is among the most expensive in the world, and an airport SIM piles a markup on top. Typical pricing in 2026 looks like this:
| Where | Typical plan | Price |
|---|---|---|
| Pearson retail SIM | Short-stay prepaid, a few GB | About CAD $45 to $60 |
| Pearson retail SIM | Larger-data 30-day prepaid | CAD $60 to $80+ |
| Online eSIM | City break, capped data (3 to 5 GB) | From about USD $15 to $20 |
| Online eSIM (unlimited) | Holafly unlimited, 7 days | Around USD $27 |
The pattern is consistent: for the same amount of data, an online eSIM comfortably undercuts the Pearson retail SIM, and it removes the hunt entirely. Because Canada's per-GB pricing is so high, an unlimited eSIM such as Holafly at roughly USD $27 for a week is often better value than buying a capped bucket at the airport, and it removes any anxiety about running out on Google Maps or video calls. The physical SIM does give you a local Canadian number, but for data-only travelers the eSIM wins on price and speed of setup.
The verdict
Buy a Canada eSIM before you fly. Use Toronto Pearson Public Wi-Fi only to confirm it is live. Keep the airport retail SIMs in mind purely as a backup if your phone turns out not to support eSIM, or if you specifically need a local number. Run the eSIM Finder to pick the right plan for your trip length.
Frequently Asked Questions
Where can I buy a SIM card at Toronto Pearson Airport?
Pearson does not have dedicated staffed SIM counters like some Asian airports. Instead, electronics and convenience shops in both Terminal 1 and Terminal 3 sell prepaid Canadian SIM cards, and there are occasional vending kiosks. The prices are high, since Canadian prepaid data is expensive and the airport adds a markup, so most travelers are better off installing a Canada eSIM before arrival.
Is there free WiFi at Toronto Pearson Airport?
Yes. Connect to the network named Toronto Pearson Public Wi-Fi, which needs no password, then accept the terms on the landing page. It covers both Terminal 1 and Terminal 3, including arrivals and gates, runs around the clock, and is the easiest way to activate an eSIM the moment you land. The exact SSID can change, so pick the network that references the airport if the name differs.
How do I get from Pearson to downtown Toronto, and will I have data?
The fastest option is the UP Express train from Terminal 1 to Union Station, about 25 to 28 minutes for a $12.35 adult fare ($9.25 with PRESTO), running every 15 minutes. The TTC bus and subway is cheaper at $3.35 but much slower, and a taxi or rideshare runs roughly $60 to $75. The UP Express has onboard WiFi, but your own eSIM gives far more reliable data the whole way in.
Is buying a SIM at Pearson cheaper than an eSIM?
Almost never. Canadian prepaid SIMs are among the most expensive in the world, and a Pearson retail SIM often runs CAD $45 to $80 or more. Online Canada eSIMs start around USD $15 to $20 for a few GB, and an unlimited Holafly plan is about USD $27 for a week. For the same data an eSIM typically costs much less and skips the queue entirely.
Should I install my eSIM before or after landing at Pearson?
Install the eSIM profile before you fly, while you still have home internet, then leave the line switched off until you arrive. When you land at Pearson, turn the eSIM on in your settings and you have data immediately, with no shop to find and no need to log in to airport WiFi first. Installing after landing works too, but only if you connect to Toronto Pearson Public Wi-Fi first.
