Toronto has two airports and the difference is worth understanding before you book.
Pearson (YYZ)
Canada’s busiest airport, 22 kilometres north-west of downtown. Terminal 1 is Air Canada and Star Alliance; Terminal 3 is nearly everyone else. A free LINK train connects them.
The UP Express reaches Union Station in 25 minutes; the 900 bus to Kipling plus subway costs a single TTC fare. See airport to the city.
Billy Bishop (YTZ)
On the Toronto Islands, two kilometres from downtown, used by Porter and some Air Canada regional flights serving eastern Canada and a number of US cities.
You reach it by a free pedestrian tunnel with a moving walkway under the harbour, or a free 90-second ferry — the shortest scheduled ferry crossing in the world. From the terminal to Union Station is fifteen minutes.
If your route offers Billy Bishop, take it.
Check which airport your ticket names.
Entry requirements
Most visa-exempt travellers flying to Canada need an eTA (Electronic Travel Authorization), applied for online for a small fee before departure. It is not issued at the border.
Americans do not need one; citizens of many other countries need a full visitor visa. Check your own position well in advance.
US preclearance
Flights from Pearson to the United States clear American immigration and customs before boarding, which means arriving earlier at Toronto and landing as a domestic passenger. Allow an extra hour.
When fares are lowest
January to March, excluding the school break, are cheapest by a clear margin.
September is expensive because of TIFF and good weather together. July and August are peak for hotels and flights, and the days around Caribana at the start of August are the busiest of the summer.
Late April, May and early June are the value months against decent weather.
Onward travel
VIA Rail from Union Station runs the corridor to Ottawa (4–5 hours), Montreal (5–6) and Windsor. Advance fares are much cheaper.
Domestic flights — Montreal 1 hour, Vancouver 5, Halifax 2. Canada is very large; Vancouver is further from Toronto than London is from Cairo.
Winter delays at Pearson are common in January and February. Build slack into tight connections.
