Kinds of connection, kinds of wait
Connections at Pearson fall into four kinds. Airside, same terminal (most Air Canada–Air Canada and WestJet–WestJet connections): no customs, no re-check, a walk between gates; a car is irrelevant. Landside, same or different terminal (international to domestic, or between airlines that do not interline): clear customs, collect and re-check bags, take the Terminal Link between terminals if needed; the airlines' minimum connection times are 60 to 120 minutes. Long layovers (four hours or more): time enough for a car into Toronto and back — 30 to 45 minutes each way off-peak — for a meal, a meeting or a look at the city. Overnight (a late arrival and a morning departure): the Sheraton Gateway at Terminal 3, the ALT at Viscount, or the airport strip's hotels on Dixon Road, five minutes by car. The Billy Bishop connection — a Porter turboprop arrival and a Pearson jet departure — is a 30 to 90 minute car across the city.
Pearson handles roughly a third of its passengers as connections — Air Canada's hub feeds the world through it, WestJet's eastern operation does the same at Terminal 3, and the international airlines' passengers connect to the domestic network — and the layover is a fact of the Toronto traveller's life. Most connections need no car at all; some need a train between terminals; and a meaningful number are long enough that the passenger would rather be in the city than in a departure lounge. This article sorts the connections by kind, explains the Terminal Link and the minimum connection times, covers the customs and baggage rules that make a landside connection slower than it looks, gives the arithmetic for a car into Toronto on a long layover, describes the overnight options, and covers the Billy Bishop–Pearson transfer that trips up passengers who assumed Porter was one airport.
Airside connections: no car, no customs
A passenger connecting between two Air Canada flights (or two Star Alliance flights ticketed together) at Terminal 1, or two WestJet flights at Terminal 3, stays airside: the bags are checked through, there is no customs (for domestic–domestic and international–international connections; international-to-domestic is different, below), and the connection is a walk between gates with the airline's published minimum connection time — as short as 30 to 45 minutes domestic, 60 to 90 international. Nothing in this article applies except the last section, on what to do if the connection is missed.
International to domestic: customs, bags and the connections desk
An international arrival connecting to a domestic departure — Frankfurt to Toronto to Winnipeg — clears Canadian customs at Pearson (the customs time article has the timings), collects the checked bags in the international hall, and re-checks them at the airline's connections desk inside the hall before proceeding airside for the domestic departure. The airlines set minimum connection times of 90 to 120 minutes for this, and on an afternoon in August the customs hall can consume all of it; passengers with tight connections tell the flight attendants, use ArriveCAN, and move fast. If the connection is at the other terminal, the Terminal Link adds fifteen minutes.
Landside connections between airlines
Two airlines that do not interline — a Flair arrival and an Air Canada departure, a charter and a scheduled flight — require the passenger to collect bags, exit to the arrivals level, take the Terminal Link if the terminals differ, and check in again from scratch with the second airline's baggage deadline. Two hours is a comfortable minimum; three is safe. A black car is not part of this connection unless the passenger wants to leave the airport in the gap.
The Terminal Link: four minutes, every few minutes
The Terminal Link is a free automated train connecting Terminal 1, Terminal 3 and the Viscount station (parking and the ALT Hotel), running every four to eight minutes around the clock with a four-minute ride between the terminals. Its stations are on the departures level of each terminal — the eastern end of Terminal 1, the northern end of Terminal 3 — so a connecting passenger goes up from arrivals, rides, and comes down to arrivals or stays at departures at the other end. With bags the whole exercise is ten to fifteen minutes. The Terminal 1 vs Terminal 3 article explains which airlines are where.
The long layover: a car into the city
A layover of four hours or more is time enough for Toronto. From Door A at either terminal the Financial District is 30 to 40 minutes off-peak (50 to 90 at the peaks — the rush hour article matters here), Yorkville 35 to 45, the CN Tower and the waterfront 30 to 40; a passenger with five hours between a London arrival and a Vancouver departure can clear customs, ride into the city, have a two-hour lunch on King West or a meeting on Bay Street, and be back at the departures curb two hours before the flight. The arithmetic: two fixed airport fares, and the hourly chauffeur alternative — one car, one chauffeur, waiting while you eat — is usually the better structure for a layover of four to six hours because the car is at the door when you come out. The visitor guide suggests what a layover of that length can see; the CN Tower article is the classic three-hour version.
The rules of the layover run: bags stay with the airline if the connection is airside (nothing to carry); bags come with you if the connection is landside (the car's trunk holds them); the return pickup is timed for the airline's check-in deadline plus the hour's traffic; and the passenger keeps the boarding pass and passport in a pocket, not in the trunk.
The layover that is too short for the city
Three hours is not enough. Customs (45 minutes in the afternoon), the drive (40 minutes each way), and the two hours the airline wants before an international departure leave no time in the city; a three-hour layover is better spent in a lounge, at the Sheraton Gateway's restaurant (a bridge from Terminal 3), or on the Terminal Link to see the other terminal. The break-even for a city run is about four and a half hours for a domestic onward flight and five and a half for an international one.
The overnight connection
A late arrival and a morning departure — a 23:30 landing from Lisbon and a 07:00 flight to Calgary — is an overnight, and Pearson has three kinds of hotel. The Sheraton Gateway is attached to Terminal 3 by a bridge from the departures level; no car needed, and a passenger at Terminal 1 takes the Terminal Link. The ALT Hotel is at the Viscount station on the Terminal Link, a train ride away. The airport strip — the Marriott, Hilton, Delta, Westin, Sheraton Four Points and a dozen more on Dixon Road, Carlingview and Airport Road — is five to eight minutes by car from Door A, at a fixed fare, and its hotels are larger and often cheaper; the airport strip guide covers them, and a car from Door A at midnight and back to the departures curb at 05:00 is a booking the hotels' desks make for guests every night. A passenger with an overnight and a free evening can also go into the city — a Yorkville hotel is 40 minutes away and the Toronto luxury hotels guide covers the choice.
The Billy Bishop connection
Porter's turboprops fly from Billy Bishop on the Toronto Islands; Porter's jets and every other airline fly from Pearson; and a passenger with a Porter Ottawa–Toronto flight connecting to an Air Canada Toronto–Vancouver flight has two airports and a car between them. The Billy Bishop guide covers the island airport's tunnel and the Eireann Quay pickup; the run from Eireann Quay to Pearson is 30 to 45 minutes off-peak via the Gardiner and 427 and 60 to 90 at the peaks, and the connection needs three hours to be comfortable. Bags are collected at Billy Bishop and checked again at Pearson. The Pearson vs Billy Bishop article explains why this connection exists.
The Hamilton and Waterloo connections
Rarer but real: a Flair arrival at Hamilton connecting to a Pearson international departure is a 55 to 75 minute car up the QEW and 427 (the Hamilton airport article); a Flair arrival at Waterloo connecting at Pearson is 60 to 80 minutes on the 401 (the Waterloo airport article). Both need four hours to be safe.
Missed connections
A missed connection — the inbound was late, the customs hall was slow — is the airline's problem to rebook and, under the Air Passenger Protection Regulations, sometimes to compensate; the passenger's car booking, if there was one at the destination, moves with the new flight number on a text to dispatch, as the flight delays article describes. A missed connection that becomes an unplanned overnight at Pearson is the overnight section above, and the airline may provide the hotel.

Booking a layover car
The engine prices a Pearson-to-city-and-back layover as two transfers or an hourly booking; the hourly page explains the minimum; and the notes field takes the onward flight number so the return is timed to it. For the Billy Bishop connection, book from Eireann Quay to Pearson with both flight numbers.
The corporate connection: a meeting between flights
A layover is sometimes the meeting. A Vancouver executive flying to Frankfurt through Toronto with a five-hour connection books a car from Door A to a Bay Street client's office, ninety minutes in a boardroom, and a car back — the executive car service article describes the Financial District pickup, and the corporate account holds the traveller's preferences so the assistant books it in a line. The timing rule is the one above: five and a half hours for an international onward flight, the return pickup set for the airline's deadline plus the hour's traffic, and the chauffeur tracking the inbound flight so a late arrival shortens the meeting rather than missing the departure.
Lounges, showers and the Sheraton's day rooms
For the layover that is too short for the city, Pearson's lounges — the Maple Leaf Lounges and the Air Canada Signature Suite at Terminal 1, the Plaza Premium lounges at both terminals with day passes for any passenger, the airline lounges at Terminal 3 — have showers, food and quiet, and the Sheraton Gateway sells day rooms by the hour across its bridge from Terminal 3. A passenger with three hours and no lounge access buys a Plaza Premium pass; a passenger with four buys a day room and a shower; a passenger with five books the car.
Children, unaccompanied minors and the connection
An unaccompanied minor connecting at Pearson is escorted by the airline between gates on an airside connection, and by the airline's staff through customs and the connections desk on a landside one — the airlines charge for the service and require it for children under a certain age. A child whose connection is the Billy Bishop–Pearson transfer, or a landside connection between airlines that do not offer the escort, needs a chauffeur with meet and greet and a handover, and the unaccompanied minors guide describes what we do and the notice we need.
Luggage storage and the layover without bags
Pearson has no left-luggage counters in the public areas, which is why the layover run into the city with landside bags carries them in the car's trunk — the chauffeur stays with the vehicle, the bags stay with the chauffeur, and the passenger walks into lunch with a phone and a passport. For an hourly booking that is the natural arrangement; for two separate transfers it is the same car if dispatch can arrange it and a different car with the bags reloaded if not, and the luggage capacity article says which class holds a long-haul family's bags.
