AD PLACEMENT — CONTEXTUAL
Since there's only one terminal, follow overhead signage rather than worrying about terminal transfers.
If you're arriving on an international flight and continuing domestically, budget extra time for Canadian customs, baggage recheck, and a second security screening.
Connecting onto a US-bound flight means clearing US preclearance, so treat it like an international departure even though you're still in Canada.
Peak congestion happens during the morning bank (6-9am) and evening bank (4-8pm) tied to Air Canada and WestJet mainline schedules.
International (European) service is largely seasonal summer charters, so infrequent schedules mean a missed connection could mean a long wait for the next flight.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
YHZ has one terminal building, so all connections are made on foot with no trains or shuttles required. Passengers arriving internationally (non-US) must clear Canadian customs and immigration, collect and recheck bags, then pass back through security before reaching departure gates; those connecting onto US-bound flights must clear US CBP preclearance, which functions like a full international security and customs check.
