Air Canada Maple Leaf Lounge (Transborder)

For Air Canada passengers heading across the border, the Maple Leaf Lounge (Transborder) sits in Terminal 1's US pre-clearance zone, serving passengers between Canadian security and the US Customs and Border Protection process. Spanning Levels 2–3 near Gates F52/F53, it is one of the more spacious transborder facilities in Air Canada's network — featuring panoramic tarmac views, a children's room, private quiet cubicles, shower suites, a hot buffet, and a full open bar.

Because the lounge sits within the pre-clearance area, guests have already committed to their US-bound flights — making this a particularly purposeful lounge visit. The atmosphere tends to be calmer than the international wing, with a more predictable mix of business travelers and leisure passengers heading south. Business Class passengers, Aeroplan elites, and Star Alliance Gold members on qualifying transborder routes all have complimentary access, making it a well-used stop before early morning flights to major US hubs.
