Canaport LNG is a receiving and regasification terminal in Saint John, New Brunswick, Canada. Construction on the facility began in 2008, and it was commissioned in June 2009. Canaport LNG is the first LNG regasification plant in Canada. It provides natural gas to Canada and the northeastern United States, and the facility is jointly owned by Repsol YPF (75%) and Fort Reliance/Irving Oil (25%).

Canaport LNG can send out 1 Bcf/d of natural gas to the Maritimes & Northeast Pipeline via the 90-mile-long Brunswick Pipeline, which was built in tandem with the LNG terminal.

On October 7, 2010, Repsol and Qatargas signed a multiyear supply deal. Under the agreement, Qatargas will deliver LNG to the New Brunswick terminal using Q-Flex as well as Q-Max ships. Capable of carrying roughly 5.6 and 4.6 billion cubic feet of natural gas, respectively, Q-Max and Q-Flex are the world's largest LNG tankers. According to Repsol, Canaport is one of the few LNG terminals that can accommodate these vessels.

Contractors for the Canaport LNG project included SNC-CENMC, G.P. (SNC-Lavalin, Saipem S.p.A.) and Kiewit-Weeks-Sandwell (Peter Kiewit Sons Co., Weeks Marine, Sandwell Engineering).
