Tips for 45 min Connections
Since YOW is a single terminal, most connections just require walking, but budget extra time if your connection involves clearing customs or US preclearance.
US-bound connections require full US CBP screening including baggage recheck, so treat these like an international departure even if your first flight was domestic.
Air Canada and WestJet flights dominate the schedule, but neither carrier operates a true hub-and-spoke bank system here, so connection options can be limited if you misconnect.
International arrivals from outside Canada must clear immigration and customs before reaching the connections area, which can add 20-30 minutes during busy widebody arrival periods.
Security lines are usually short outside peak morning and early evening periods, making tight connections more manageable than at larger Canadian hubs like YYZ or YVR.

Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
All operations happen within a single terminal building, so passengers move between zones entirely on foot via connecting corridors. Passengers arriving internationally must clear Canadian customs and immigration before continuing, and those flying onward to the US must pass through US preclearance security and CBP screening, both of which require re-entering the departures side.
