Halifax Stanfield International Airport (IATA code: YHZ) is Atlantic Canada's premier full-service airport, connecting passengers and cargo customers to global markets. It is a medium-sized facility providing a comfortable environment for passengers. Leisure facilities, including library vending machines and the observation deck, are good for longer waiting times at the airport. Map directories offer excellent information, and some additional improvements continue to be made to the terminal infrastructure.

 YHZ was built by the Department of Transport near Kelly Lake, on land provided by the City of Halifax. It is presently operated by the Halifax International Airport Authority and opened in June 1960.

Halifax Stanfield has two runways arranged perpendicular to each other. In press releases, the airport authority refers to the longer one as the "main runway" and the shorter one as the "secondary runway."

Today, the terminal serves over four million passengers per year. The ground floor houses an expanded security screening area, increasing capacity and allowing for the implementation of "CATSA Plus", the Canadian Air Transport Security Authority's latest checkpoint design, which requires more space. The second floor contains an expanded, double-height passenger waiting area, with additional seating, as well as new dining and retail space. At the same time, new security features were added around the terminal, including anti-ramming bollards, blast-resistant glazing, more security cameras, and new access control features.

The terminal now has a total of 32 gate positions, with 13 using airbridges (gates 12, 14–16, 18, 20, 22–24, and 26–28). The remaining gates are ground-loading positions. Gates 22–24 and 26–28 are swing gates: a glassed-in secure corridor allows incoming international passengers and pre-cleared departing US passengers to be segregated from those in the domestic/international departure lounge; when used for US departures, these gates are numbered 52–54 and 56–58, respectively. Gates 2 (a-e) to 9 are ground-loading positions dedicated to domestic regional operations. Gates 34 to 46 are ground-loading gate positions for US flights.

MetroX Route 320 is an express bus service that travels between the city centre and the airport, with intermediate stops at the Dartmouth Bridge Terminal and the suburb of Fall River. The route is operated by Halifax Transit and runs all day on both weekdays and weekends.

The airport is located at Exit 6 of Highway 102, which connects Halifax to the Trans-Canada Highway. It is a 28-minute drive from Halifax City Hall, the centre of Downtown Halifax. There are numerous car rental agencies located on the lower level of the airport car park.

Aside from the parking garage connected to the terminal, the airport also offers Park 'N Fly Airport Parking, a long-term parking service, the brand name licensed to the airport by Hong Kong company CK Hutchison Holdings.

Halifax Stanfield International Airport is certified by Skytrax as a 4-Star Regional Airport for facilities, comfort, cleanliness, shopping, food & beverages, staff service and security.
