Air Canada operates daily nonstop service from Hartsfield-Jackson to Toronto-Pearson and Montreal-Trudeau, with departures from Concourse C. Both routes use Air Canada's mainline narrow-body equipment (typically A220 or A320).
Despite operating from Concourse C, Air Canada flights are technically international departures and require U.S. customs pre-clearance is NOT performed at ATL — customs/immigration processing happens upon arrival in Canada. Check-in is at the Domestic Terminal North lobby.
Air Canada is a Star Alliance member, so Star Alliance Gold passengers (United Premier 1K, Lufthansa HON Circle, ANA Diamond, etc.) can use Air Canada's premium check-in and the international premium lounge on Concourse E.
Bag policy includes one free carry-on plus a personal item, and one free checked bag for transborder flights to Canada. Premium economy and business class include additional checked bags and priority boarding.
Connection options at the Toronto and Montreal hubs are extensive across Air Canada's global network. Travelers connecting from a U.S. domestic flight to an Air Canada international flight via Toronto or Montreal often find this routing competitive with Delta's direct international service.
