[1] Quebecair began as Rimouski Airlines in 1947 and flew under that name until it merged with Gulf Aviation in 1953 under the name Quebec-Air.

As operations increased, the company introduced a new, larger aircraft in the form of the Convair CV-540 turboprop, which were put on the main route between Montreal and Quebec.

In 1984 Quebecair leased two Douglas DC-8-63s for transatlantic charter flights, but these stretched Super DC-8s were not operated very long and merged with Regionair.

[5] According to the October 1985 Quebecair timetable, the airline was operating scheduled passenger flights on two international routes, being Montreal-Boston and Quebec City-New York City.

The financial situation at the carrier forced the Quebec government (which had owned the airline for several years) to sell the company to CP Air in July 1986.
