🛫 Three Concourses, One Building

Layout: Domestic, US Transborder (post-preclearance), and International gates on a single airside floor. Two passenger-screening lines: one for domestic + international, one for US-bound.

Airport Station: the new O-Train Line 4 station sits directly at the Departures level — about 60 seconds’ walk from the curb.

📍 Uplands — The Southern Airport District

YOW is in the Uplands neighbourhood of south Ottawa, bordered by Riverside South and the Greenboro suburbs. The airport is operated by the Ottawa International Airport Authority (OIAA) on land that was historically the RCAF Uplands base.

O-Train Airport Station connection: Line 4 platform is integrated with the terminal — escalator/elevator straight to Departures.

eTA — CAD 7, Five-Year Validity

Visa-exempt non-Canadians flying into Canada need an Electronic Travel Authorization (eTA) at CAD 7, valid up to 5 years or until passport expiry. Most approvals come within minutes via canada.ca/eTA. US citizens are eTA-exempt. The eTA is required for air arrivals only.

PIK Kiosks & CBSA Declare App

All YOW international arrivals are processed at CBSA Primary Inspection Kiosks (PIK). Scan passport, answer customs questions on-screen, take a photo, receive a receipt for the exit officer. The CBSA Declare app lets you file the declaration up to 72 hours pre-arrival and skip part of the queue.

US Preclearance — 4:15am to 7:20pm

YOW has full US CBP preclearance — clear US immigration in Ottawa before boarding, arrive in the US as a domestic passenger. Operating hours 4:15am-7:20pm daily (seasonal variation). Arrive 2.5 hours before US flight departure. Late evening US flights run past CBP closing time but the inspection must be completed before then.

⭐ O-Train Line 4 — The Train to Downtown (since 2025)

• Route: Airport Station (Departures level) → Uplands → South Keys (4 km, 8 min on Line 4 alone). Transfer to Line 2 northbound for Bayview, then Line 1 to Rideau or Parliament.
• Total time to downtown Rideau Station: approximately 35-45 minutes with the two transfers.
• Frequency: every 8-10 min peak (7-9 a.m., 3:30-6 p.m.), 12-15 min off-peak.
• Hours: Mon-Fri 6:00 a.m. – midnight; Sat 6:30 a.m. – midnight; Sun 7:30 a.m. – 11:30 p.m. Line 4 does NOT run 24 hours — late-night arrivals need Bus 97 or a taxi.
• Fare: CAD 4.10 single ride with PRESTO (no airport surcharge). Pay with PRESTO card, tap a credit card at the gate, or load via the OC Transpo app. Cash fare from the bus is higher.
• Rolling stock: Alstom Coradia LINT 41 diesel multiple units — heated, fully accessible, gate-style seating, dedicated luggage racks.

🚌 Bus 97 — Still the Express Option

• OC Transpo Route 97 continues to run after the train opened — express service from YOW to downtown via the Transitway and the rapid-transit corridor.
• Journey: roughly 30 minutes to Rideau Centre / Parliament Hill.
• Fare: CAD 3.65 single ride with PRESTO or contactless tap.
• Frequency: every 10-30 minutes, running 24 hours daily — the only option for very early or very late YOW arrivals when Line 4 is closed.
• Pickup: Bus 97 stop is on the arrivals curb near the central door; tickets at the ground-transportation booth.

🚕 Taxis & Rideshare

• Airport taxi flat-rate or metered: typically CAD 35-45 to downtown, 15-20 min via Bronson Avenue or the Airport Parkway. Cash and card accepted.
• Uber and Lyft: both active at YOW; dedicated rideshare pickup at the curb. Typical CAD 25-40 in normal demand.
• The downtown trip is short. A taxi is often only CAD 10-15 more than the train + transfers, and saves the 35-45 minute multi-segment ride. If you have luggage and a tight timeline, take a cab.

🚗 Rental Cars & the Airport Parkway

All major brands (Avis, Budget, Enterprise, National, Hertz, Discount, Thrifty) sit in the airport parkade — 2-3 min walk from arrivals. The Airport Parkway feeds directly onto Hunt Club Road and Highway 417 (the Queensway), the main east-west route through Ottawa-Gatineau. Ottawa traffic is lighter than Toronto or Montreal but Queensway congestion in the morning rush (7:30-9 a.m. eastbound) is significant.

🛋️ Aspire Salon Lounge — Priority Pass Default

Hours: daily 4:30 a.m. – 9:15 p.m.

Access: Air Canada Business Class, Aeroplan Super Elite/Elite (and 50K with status caveats), Star Alliance Gold passengers with a same-day Star Alliance international or transborder flight.

The flat fried-dough pastry that anyone in Canada has eaten was invented in Killaloe, Ontario in 1978 and made famous from a stand on the Rideau Canal in Ottawa. Cinnamon-sugar is the classic; chocolate-banana and the Killaloe Sunrise (cinnamon-sugar + lemon) are the local picks. CAD 8-12 from the original kiosks at ByWard Market and along the canal. The airport version exists but it isn’t the same thing.

Quebec invented poutine but Ottawa is the bilingual capital and the city eats more poutine per capita than most. Chez Lucien on Murray Street, La Poutine and a dozen stands in ByWard Market do the proper Québécois version — fresh-cut fries, cheese curds that squeak, hot gravy poured at the table. CAD 12-18 (~€8-12). YOW airside has a credible version at one of the food-court stands but it cools too fast in the to-go containers.

The covered market and the streets around it (William, York, George, Murray) host a tight cluster of restaurants and stalls — oysters at Whalesbone, Lebanese, Vietnamese, French-Canadian and Indigenous-inflected kitchens are all within five minutes of the central market hall. The market itself has been working since 1826 — older than Canadian Confederation. Worth a layover trip if you have 4+ hours.

Top Shelf Distillers (Perth, ON, 90 minutes southwest of Ottawa) makes the most-distributed Ottawa-area craft gin and whisky. Their Dubliner-style Irish whisky and Bonny Doon gin are sold at the YOW duty-free at CAD 45-65 for 750ml. Local craft beer at the airport is hit-or-miss — the better Ottawa beers (Beyond the Pale, Dominion City, Big Rig) require a trip into town.

🍁 Quebec Maple Syrup

CAD 15-30 (~€10-20) per 250-500ml. Quebec produces ~71% of world maple syrup; the Outaouais region (Gatineau side) is right across the river from Ottawa. Look for Grade A Dark or Very Dark — more flavour than the pale grades that get exported as premium.

🥃 Crown Royal & Canadian Whisky

CAD 35-70 (~€23-47) per 750ml. The duty-free at YOW carries Crown Royal Reserve, Northern Harvest Rye (named World Whisky of the Year 2016), and the regional Top Shelf Distillers products. Genuinely Canadian, drinkable, exportable.

🍫 Hudson’s Bay & Canadian Chocolates

CAD 12-25 (~€8-17) per gift box. The YOW duty-free carries Purdy’s (BC-based, founded 1907), Laura Secord, and Hudson’s Bay Company-branded gift boxes. Skip the generic maple-leaf chocolates — the Purdy’s hedgehogs are the better gift.

🎒 Hudson’s Bay Stripes & Roots Apparel

From CAD 30 / ~€20. A Hudson’s Bay Point Blanket (the iconic green-red-yellow-indigo stripes, in production since 1779) at the duty-free is more credibly Canadian than a hockey jersey. Roots cabin socks and toques are the cheaper option.

The Gothic Revival Centre Block of Parliament (the one with the Peace Tower) has been closed for major rehabilitation since 2018 and is not expected to reopen until the early 2030s. The House of Commons and Senate now sit in the West Block and the former Government Conference Centre. You can still walk the grounds, see the Centennial Flame, watch the Changing of the Guard (summer, daily 10 a.m.) and visit the Library of Parliament. The Parliament Hill exterior is the photograph; the interior tour isn’t available during the renovation window.

The Rideau Canal, built 1826-1832 to provide a military supply route from Montreal to Kingston that bypassed the St. Lawrence River, is a UNESCO World Heritage Site since 2007 — the oldest continuously operated canal system in North America. From late December to early March (weather permitting), the 7.8 km section through downtown freezes and becomes the world’s largest naturally frozen skating rink. The 2023-24 season was the first to have zero skating days because of warm winters; verify ice status before you fly in expecting to skate.

The Canadian Tulip Festival runs 8-18 May 2026 at Commissioners Park on Dows Lake — over 300,000 tulips, free admission, Tulip Trail and CIBC Tulip Trek pay-experiences at CAD 5. The festival commemorates a 1945 gift from Princess Juliana of the Netherlands, who took refuge in Ottawa during WWII (Dutch Princess Margriet was born here, with the maternity ward declared Dutch territory so she could inherit the Dutch throne). The O-Train Line 2 (Trillium) drops you at Dow’s Lake Station, 5 minutes from the park.

The National Gallery of Canada (Sussex Drive, designed by Moshe Safdie, opened 1988) houses the country’s finest Group of Seven and Indigenous-art collections. Outside the entrance sits Maman, the 9-metre bronze spider by Louise Bourgeois (1999) — one of seven casts worldwide, the others at Tate Modern, Bilbao, Roppongi Hills, Doha, Seoul, and St. Petersburg. Admission CAD 20 adult, free for under-12 and for Indigenous visitors. The Bytown Museum at the foot of the Rideau Locks tells the canal-construction story.

At YOW: the Alt Hotel Ottawa Airport is across from the terminal, CAD 175-260 per night. Downtown: the Westin Ottawa (canal-side at Rideau Centre), the Fairmont Château Laurier (the 1912 château hotel beside Parliament — the photo-icon of Ottawa hotels), the Andaz Ottawa ByWard Market (boutique, near the food). All 35-45 min back to YOW via Line 4 in the morning.

Canadian networks (Rogers, Bell, Telus, Freedom Mobile, Public Mobile, Lucky Mobile, Fido) sell prepaid SIMs at outlets along Bank Street and at the Rideau Centre. US visitors with T-Mobile or AT&T usually get Canadian roaming included on standard plans. EU/UK Roam-Like-At-Home does NOT extend to Canada — get a Canadian SIM or an eSIM (Airalo, Holafly). 5G is default across Ottawa-Gatineau.

With 4 hours airside-to-airside, the realistic YOW move is the ByWard Market + Parliament Hill exterior. O-Train Line 4 → Line 2 → Line 1 → Rideau Station (~40 min), walk through ByWard Market for a poutine or pho lunch, walk five blocks west to the Parliament grounds for photos, return. Round-trip transit is ~90 min + 90 min in the city = 3 hours, leaving an hour buffer for security and unforeseen delays. Under 4 hours, stay airside. For US-bound layovers, add 30-45 min for CBP preclearance.
