Montréal is served primarily by Montréal–Trudeau International (YUL), the region’s main international hub handling long-haul and transborder flights and home to full-service carriers alongside several international and low-cost airlines. It sits about 20–25 minutes (20 km) west of downtown by car; express buses, commuter trains, taxis and ride‑shares typically take 25–40 minutes depending on traffic, with fares ranging from economy transit prices to moderate taxi/ride-share rates. For budget travelers, Montréal–Mirabel (YMX) now functions largely for cargo and some charter operations rather than regular passenger service, so most leisure and business travelers use Trudeau. Pros: wide route network and modern passenger facilities; cons: peak-hour road congestion and variable parking/transfer costs.
Ottawa Macdonald–Cartier International (YOW) serves as the city’s main gateway, functioning as a mid-sized international and domestic hub that typically handles a mix of national carriers and seasonal international services. Major Canadian airlines and several low-cost operators usually offer most flights, with fares often seen as competitive for the region. The airport sits about 10–15 km south of downtown Ottawa; driving takes roughly 15–25 minutes depending on traffic, while taxi or rideshare fares can commonly fall in a mid-range bracket and public buses take about 30–40 minutes with modest fares. Pros: relatively compact terminals and convenient downtown access. Cons: fewer long-haul nonstop options than larger hubs and potential peak-time congestion.
