Ottawa YOW Airport: Complete Traveler’s Guide
Loading article…
Ottawa Macdonald-Cartier International Airport (IATA code: YOW) is the main gateway to Canada’s federal capital. Every year, more than 4 million passengers pass through for domestic, transborder and international flights. This guide covers the terminal, the lounges, parking, ground transportation and American preclearance.
Since January 2025, YOW also has its own light rail station, which changes how you reach downtown entirely. To get the most out of every trip, see our picks for the best travel credit cards in Canada.
General information about Ottawa Airport YOW
The airport sits about 14 km south of downtown, at 1000 Airport Parkway. A single terminal handles every flight. That layout keeps things simple: no inter-terminal shuttle and no long walks between gates.
| Detail | Information |
|---|---|
| IATA code | YOW |
| Official name | Ottawa Macdonald-Cartier International Airport |
| Address | 1000 Airport Parkway, Ottawa, Ontario |
| Terminals | 1, across three levels |
| Annual passengers | More than 4 million |
| Lounges | 2 |
| Rail link | O-Train Line 4, station inside the terminal |
Wi-Fi is free throughout the terminal. Just connect and accept the terms of use.
Terminal layout and navigation
The single terminal spreads across three levels. That vertical layout makes finding your way straightforward.
- Level 1, arrivals: baggage carousels, car rental counters and exits to ground transportation
- Level 2, gates: access to the gates and airport administrative offices
- Level 3, departures: check-in counters, security, American preclearance and the O-Train station
Boarding gates
Gates are split by destination, which reflects the physical separation between flights to the United States and everything else.
- Gates 1 to 6, 11 and 12: transborder flights, inside the American preclearance zone
- Gates 13 to 28: domestic and international flights outside the United States
Getting downtown
Four options connect YOW to downtown Ottawa, 14 km away. Since 2025, the train joins the bus, the taxi and the car.
O-Train Line 4, the Airport Link
Line 4 links Airport station, built into the terminal at the departures level, to South Keys station in 8 minutes. This 4 km branch has three stations: Airport, Uplands and South Keys.
- To downtown: about 57 minutes to Rideau station, with two transfers
- Transfers: South Keys to switch to Line 2 (Trillium), then Bayview for Line 1 (Confederation)
- Fare: $4.10 for a single ride, with no airport surcharge
- Payment: Presto card, credit card, debit card or mobile wallet, tapped directly
OC Transpo bus
Route 97 still serves the airport and complements the train, particularly when the latter is not running. During regular hours it terminates at Hurdman East station, where connections lead downtown. Early morning and late evening, the service continues through to Rideau station.
One catch: route 97 does not run between 2 a.m. and 6 a.m. Plan on a taxi for that window. The fare matches the train at $4.10 a ride, and OC Transpo’s fare cap makes trips free after 34 taps in a month.
Taxi and rideshare
- Taxi: cars queue outside the central arrivals door. Expect roughly $35 to $40 downtown. An attendant on site arranges an accessible vehicle when needed
- Uber and Lyft: both serve YOW. The airport charges $3.25 for drop-off and $4 for pickup, added to the fare. Expect $25 to $40 in total
Car rental
Eight agencies sit in the Parkade (P1): Alamo, Avis, Budget, Enterprise, Hertz, National, Routes and Thrifty. Pay with a credit card that includes collision coverage to skip the counter’s insurance.
Parking at YOW
YOW runs two paid lots and one free waiting area. The offering is simpler than Montreal’s or Toronto’s, and the rates stay among the lowest at major Canadian airports.
| Parking | Distance | 24 hours | Long stay |
|---|---|---|---|
| Parkade P1 (covered) | Linked to the terminal by two skywalks | $26.00 | Not offered |
| P4 (long-term and overheight) | Short walk | $21.00 | $105.00 / 7 days, $210.00 / 30 days |
| Cell Phone Lot | Nearby | Free | Waiting area only |
- Hourly rate: $6.00 per 30-minute block in both lots, up to the daily maximum
- Book online: the rate drops below the gate price, and CAA members get an extra discount
- EV charging: free 120 V outlets in the Parkade, plus three 100 kW chargers across from the Cell Phone Lot
- Parking office: on Level 1 of the Parkade, staffed 24 hours a day
For drop-off, use the elevated roadway on Level 3, in front of the check-in counters. For pickup, head to the arrivals curb on the lower roadway, between pillars 1 and 3. The curbs are for active loading only: an unattended vehicle will be towed.
Our guide to saving on airport parking covers Ottawa too, and explains how to cover part of the bill with points.
Airport lounges at YOW
YOW has two lounges, both near gate 18, in the Canada and International departures zone. The offering is thinner than Toronto’s or Montreal’s, but it covers the essentials for holders of the right cards.

- Scotiabank Passport cards: the Scotiabank Passport® Visa Infinite Privilege* Card includes 10 visits a year
Security and preclearance
YOW has two separate checkpoints on Level 3: one for Canada and International flights, one for flights to the United States. The second includes American preclearance, which sets Ottawa apart from most regional Canadian airports.
CATSA security screening
- Opening: 4 a.m. in high season, 3 a.m. during charter season from November to April
- Trusted Traveller lane: open to NEXUS and Global Entry members, crews, military and police. Full service from 4 a.m. to 8 a.m. and from 2:30 p.m. to 6:30 p.m.
- United States side: no Trusted Traveller programme, the regular lanes apply
NEXUS and preclearance
Travellers to the United States clear American customs in Ottawa, before departure. They then arrive as if on a domestic American flight, with no line on arrival. The NEXUS processing fee is US$120 for five years, and several travel credit cards reimburse it.
- CBP hours: 4:15 a.m. to 7:20 p.m. daily, with seasonal variation
- Peak periods: 4:30 a.m. to 7 a.m. and 3 p.m. to 7 p.m.
- Mobile Passport Control: a free app that opens an express line
- NEXUS enrollment on site: YOW offers Enrollment on Arrival, with the Canadian interview by appointment on Level 1

Airlines and destinations
About ten airlines serve YOW, flying to Canada, the United States, the Caribbean, Mexico and Europe. Air Canada and WestJet dominate the schedule.
- Air Canada: the main carrier, with Toronto, Montreal, Vancouver, Calgary, Halifax and several American cities
- WestJet: Calgary, Edmonton, Winnipeg, Halifax and seasonal sun destinations
- Porter Airlines: Toronto Billy Bishop, Montreal, Halifax and several cities in the American Northeast
- United Airlines: flights to the American hubs, Newark in particular
- Air France: the only scheduled transatlantic route, to Paris-Charles de Gaulle, five to seven times a week depending on the season
- Air Transat, Flair, Canadian North, PAL Airlines: seasonal additions and regional routes
For most other international destinations, a connection in Toronto or Montreal is still required. It therefore pays to cover the whole itinerary in Aeroplan points rather than buying two separate tickets.
| Connection | Flight time | Airlines | Frequency |
|---|---|---|---|
| Ottawa to Toronto (YYZ) | About 1 h | Air Canada, Porter | More than 15 flights a day |
| Ottawa to Montreal (YUL) | About 45 min | Air Canada, Porter | More than 10 flights a day |
| Ottawa to Toronto Billy Bishop (YTZ) | About 1 h | Porter | Several flights a day |
| Ottawa to Newark (EWR) | About 1 h 30 | United Airlines | Several flights a day |
| Ottawa to Paris (CDG) | About 7 h 30 | Air France | 5 to 7 flights a week |
Services, restaurants and shops
Airside, the offering covers the basics: The Prescott for a full meal, Tim Hortons, Subway and Starbucks for a quick stop. On the retail side you will find a duty-free shop, InMotion for electronics accessories and souvenir shops.
For duty-free or overseas purchases, a card with no foreign transaction fee saves you the 2.5 % normally charged on currency transactions.
Lesser-known services
- PARS 2000 storage: on Level 1, near carousel 5. Leave coats, boots or bags there during the trip, 24 hours a day
- SAVM concierge: curb-to-cabin assistance, security and customs included, available at all hours
- Pet relief areas: one outdoors in front of the terminal near the Parkade, one at gate 18 and one in the United States zone

No hotel sits on the airport grounds itself. Several properties are a few minutes away by car, though, with a free shuttle to the terminal.
| Hotel | Loyalty programme | Distance from YOW |
|---|---|---|
| Hilton Garden Inn Ottawa Airport | Hilton Honors | About 5 min by car |

Tips for frequent travellers
Here are five habits that save time and money in Ottawa.
- Take the train if you leave early: $4.10 against $35 to $40 by taxi, and the station is inside the terminal
- Use your lounge before preclearance: both lounges stay in the Canada and International zone
- Park at P4 from three days on: $21 a day against $26 at the Parkade, and $105 for a full week
- Watch the last flight to the United States: preclearance closes at 7:20 p.m., delay or no delay
- Do your NEXUS interview on site: YOW offers Enrollment on Arrival, which saves a trip to Montreal or Toronto
Conclusion
YOW is compact and easy to move through. Its single terminal keeps things simple, American preclearance speeds up trips south, and the train’s arrival in 2025 solved the old downtown access problem. The direct-flight offering stays thinner than Toronto’s or Montreal’s, but the frequent shuttles to those two hubs make up for it.
