Toronto eSIM guide: Pearson airport, the subway and Niagara Falls

Our Canada plans connect to Rogers, with 5G where Rogers has it. Rogers says its coverage maps are approximate and that a 5G connection depends on the phone, the signal, the terrain and how busy the network is. (source)

In May 2026 Rogers said it had added network equipment at Pearson airport, Union Station and some TTC subway stations, as part of $22 million in 5G+ upgrades around BMO Field for the World Cup. It also said it parked temporary cell sites on wheels in busy downtown areas. (source)

Our Canada plans show a US internet address, so a few Canadian websites and apps may treat you as being in the US.

Pearson has free Wi-Fi in its terminals. Pick the network called Toronto Pearson Public Wi-Fi, accept the terms on the page that opens and choose Connect. The airport's page lists no time limit, which makes it a good place to download offline maps if you skipped that at home. (source)

Chatr sells prepaid SIM cards and eSIMs at two counters on the Arrivals level. The Terminal 1 counter is next to the CIBC kiosk and opens daily from 6 a.m. to midnight. The Terminal 3 counter is beside Tim Hortons and opens daily from 9 a.m. to midnight. (source)

Chatr tells buyers to bring a passport or other government ID, because it may be needed to register the SIM. It also says the phone must be unlocked, which is the same requirement our eSIM has. (source)

Chatr's plans run on the Rogers network, and its plans page describes the data as Fast 4G. They are monthly plans, so a five-day visit still pays for a month. What they add is a Canadian phone number, which our data-only eSIM does not have. (source)

The UP Express train links Pearson and Union Station, and GO Transit says its trains have free Wi-Fi. The same network, GO Wi-Fi Plus, runs on all GO trains and GO buses and at most GO stations and bus terminals. (source)

To connect, join GO Wi-Fi Plus and open gopluswifi.com in your browser. It is a handy backup if your eSIM is still being set up when you board. (source)

Uber says you can request rides around Toronto at any hour and has a separate pickup page for Pearson. Booking a ride and watching the car arrive both need data on the spot, which is the moment a working plan matters most. (source)

The TTC says riders can now get cell service at all stations on Lines 1, 2, 4, 5 and 6 and in a number of tunnels, to talk, text, stream and reach emergency services. It publishes a map of where 5G works, dated July 2026. (source)

The TTC does not say every tunnel is covered, so expect short gaps between some stations. Load your route before you go underground. (source)

The TTC also says you can call 9-1-1 anywhere in the subway where 5G is available, on any carrier. (source)

For the history: in April 2025 Rogers said the old subway network reached only 25% of the tunnels. It set targets of 80% of tunnels by the end of 2025 and all 75 stations and tunnels by the end of 2026. Those were targets, so treat the TTC's map as the current picture. (source)

GO Transit runs trains to Niagara Falls GO station, at the north end of the city, seven days a week, and says those trains have GO Wi-Fi Plus on board. (source)

Niagara Falls sits on the US border. A US carrier's support page explains that a phone near the border connects to the strongest signal, even when the tower is in the other country. (source)

That matters for our Canada plans, which work in Canada only. If your phone picks a US tower, the Canada eSIM has no data until it is back on a Canadian network. You can try choosing Rogers by hand in your phone's network settings. If you will cross to the US side, our North America plan covers Canada and the US on one eSIM.
