YTZ vs YYZ for the downtown Toronto traveller

Billy Bishop Toronto City Airport (YTZ) sits 90 seconds across a pedestrian tunnel from a parking lot at Bathurst and Eireann Quay. Pearson (YYZ) is 28 km west, accessible via the 401 westbound — which during the morning rush is the second-busiest stretch of road in North America. For the downtown Toronto traveller making a same-week flight booking, the right airport depends on exactly two things: where you’re flying and how much you’re willing to pay in fare to save the time. Here’s the math.

How exactly do you get to YTZ from downtown?

YTZ is on the Toronto Islands. There are two ways to reach it: the free pedestrian tunnel that runs from a small lobby at the foot of Bathurst Street (under Eireann Quay) to the terminal under the harbour, and the free ferry that crosses the same gap on the surface every 15 minutes. The tunnel is open 24/7 and takes about 6 minutes door-to-terminal counting the four moving walkways and one elevator. The ferry takes about 7 minutes plus boarding time.

From a King and Spadina address, a chauffeur drop at the YTZ tunnel lobby takes 5 minutes door-to-door. From Bay and Front it’s 8 minutes. From Yonge and Eglinton (midtown) it’s 18 minutes with the Spadina or Avenue Road approach. The chauffeur flat rate from downtown to the YTZ tunnel is $49 — substantially less than YYZ ($89) because the drive is shorter and there are no 401 tolls or 410 detours.

For frequent YTZ travellers — Bay Street lawyers commuting to Boston and Manhattan offices weekly, downtown corporates with offices in Montreal — the YTZ chauffeur is genuinely faster than walking to the tunnel lobby. The chauffeur drops you at the door, takes your bags inside if requested, and you’re at the gate 12 minutes after pickup.

Which destinations does YTZ serve?

YTZ is essentially a Porter Airlines hub. Porter runs direct flights from YTZ to: Boston, New York Newark (EWR), Washington Dulles (IAD), Chicago Midway (seasonal), Halifax, Montreal, Ottawa, Quebec City, Thunder Bay, Sault Ste Marie, Sudbury, Windsor, and Mont Tremblant (winter seasonal). A small number of Air Canada Express flights also operate from YTZ to Montreal.

Porter’s recent expansion has added more destinations including some western Canadian routes operating with their new Embraer E195 fleet — calgary, Edmonton, and Vancouver direct flights launched in 2024–2025. Check the live Porter schedule for current routes; the network is genuinely growing.

What YTZ does not have: any international flight beyond the U.S. Northeast Corridor; transatlantic or transpacific flights; any Lufthansa, Emirates, KLM, British Airways, Singapore, Cathay, ANA, or comparable carrier; charter flights; freight or cargo; long-haul Air Canada or WestJet routes. If your destination is outside Porter’s footprint, YTZ doesn’t fly there, period.

What’s the actual time-savings of YTZ vs YYZ?

For a Boston trip, downtown to gate the math runs: YYZ option = 28-minute chauffeur to T1 + 90 minutes for U.S. pre-clearance and security + 30 minutes gate-side = roughly 2h30 door-to-gate. YTZ option = 5-minute chauffeur to tunnel + 6 minutes through tunnel + 12 minutes Porter check-in and security (notably faster than YYZ) + 15 minutes lounge = 38 minutes door-to-gate. YTZ saves 90+ minutes on total trip time for a Boston flight.

For a Montreal trip, the math runs YYZ = 28 min chauffeur + 60 min domestic security + 20 min gate = 1h48 door-to-gate. YTZ = 5 min chauffeur + 6 min tunnel + 10 min security + 15 min lounge = 36 minutes door-to-gate. YTZ saves 70+ minutes for a Montreal flight.

The pattern holds for every Porter direct destination: YTZ’s small-terminal advantage and the elimination of the 401 drive shrinks the door-to-gate time by 60–90 minutes versus the equivalent YYZ flight. On the back end (return arrival), YTZ’s bag claim is 4–6 minutes from gate to curb; YYZ’s is 35–60 minutes. Add another 30–50 minutes saved on each return flight.

What about cost comparison on the fare?

Porter direct from YTZ to Boston runs in the $250–650 round trip range depending on advance booking. The equivalent Air Canada or United from YYZ runs $300–800. Porter is competitive on cost, often slightly cheaper, with the upside that the fare includes a free lounge (Porter lounge airside at YTZ has snacks, drinks, and Wi-Fi), free checked bag on most fare classes, and Porter’s higher service tier (proper meal on flights over 2 hours, included rather than buy-on-board).

For YYZ-only routes (most international, transatlantic, transpacific), Porter doesn’t fly so the comparison doesn’t exist — you’re flying Air Canada or your destination’s flag carrier from YYZ. The chauffeur flat rate to YYZ from downtown is $89 versus $49 to YTZ, but if the airline only flies from YYZ, the airport choice isn’t a choice.

For chauffeur math specifically: if you’re a frequent Boston / NYC / DC / Montreal traveller, the $49 vs $89 chauffeur difference adds up. Over 30 round trips per year, that’s $2,400 in chauffeur savings on top of the time savings.

What are the practical things to know about YTZ?

First, YTZ operates 6:45 a.m. to 11:00 p.m. only. There’s a strict noise bylaw on the Toronto Islands and the airport is silent overnight. If your flight is the 6:00 a.m. or the midnight to anywhere, YTZ isn’t an option — you’re going to YYZ.

Second, the YTZ terminal is small (single concourse, 12 gates) which is both an asset (calm) and a constraint (not much retail or dining; if you have a 90-minute delay your options are the Porter lounge or the small food court). For couples and families with kids, the smaller scale is generally a relief; for travellers planning a leisurely 2-hour pre-flight meal, YYZ has more options.

Third, YTZ is weather-sensitive. The runway is short (1,219 m) and the airport sits on a small island in Lake Ontario; certain wind and fog conditions trigger diversions or delays more often than YYZ. Porter publishes its on-time performance — historically around 80–85% on-time — and the diversion rate is low but non-zero. Build a 60-minute buffer into tight-connection itineraries.

Fourth, YTZ does not have any U.S. pre-clearance facility. All U.S.-bound flights from YTZ clear customs on arrival in the U.S. (Porter flights land at non-pre-cleared terminals like Newark Terminal A, Boston Logan, Washington Dulles). This is different from YYZ T1, which is pre-cleared. For a downtown traveller going to Boston, the YTZ option means no pre-clearance line in Toronto and a fast walk-off at Boston Logan.

How does the chauffeur handle a YTZ booking differently?

The mechanics are slightly different from a YYZ run. The chauffeur drops you at the YTZ tunnel lobby on the Bathurst side — there’s a curb-cut zone for limousine drop-offs at the foot of the Eireann Quay slip road. From there you walk into the tunnel lobby, through the four moving walkways, into the terminal. The chauffeur does not cross to the island; the terminal-side ground transportation is a separate dispatch (Porter operates an island-side limo lot via a separate vendor for arriving passengers but most downtown returns book a chauffeur to pick them up at the tunnel exit on the Bathurst side).

For the inbound side, the chauffeur stages at the Bathurst side tunnel lobby waiting curb. You walk out of the tunnel and the car is at the curb. The 90 minutes of free wait time built into every booking covers the variable arrival times. Live flight tracking on the inbound flight is the same as for YYZ.

For travellers with mobility issues, large amounts of luggage, or a preference to skip the tunnel walk altogether, Porter operates a free shuttle bus from the tunnel lobby to the terminal — about 4 minutes, accessible. The chauffeur drops at the same Bathurst tunnel lobby in either case.

When does the math definitively favour YTZ?

YTZ wins when all of these are true: your destination is on Porter’s direct network; you’re flying during YTZ operating hours (6:45 a.m. to 11:00 p.m.); your trip is leisure or business with no need for an international long-haul or transcontinental connection; you value the calmer terminal experience; and you’re departing or arriving downtown. For any of the corporate Bay Street / Boston / Manhattan / DC commuter triangle of trips, YTZ is the right answer almost every time.

YYZ wins when your flight is on a non-Porter airline; your destination is international, transatlantic, or transpacific; your flight is before 6:45 a.m. or after 11:00 p.m.; you have a connecting flight that requires the larger airport’s connection network; or your origin is not downtown Toronto (anyone in Mississauga, Brampton, Vaughan, or further is going to YYZ regardless of destination).
