What aircraft replaced Trans-Canada's passenger Lancasters on the Atlantic?

In 1943, an Avro Lancaster that TCA called the Lancastrian began flying a wartime service between Montreal and Prestwick. Between 1943 and 1947 the airline operated the Canadian Government Trans-Atlantic Air Service (CGTAS), a transatlantic link for military passengers and mail using Avro Lancastrian aircraft, modified Lancasters. After the war, the Lancastrians became part of TCA and carried fare-paying civilian passengers.

The Lancastrians remained in service until replaced by a Canadian-built version of the Douglas DC-4. In 1947 they were withdrawn from service and replaced by the Canadian-built North Stars, designated DC-4M2. The fleet of Merlin-powered Canadair North Stars was delivered starting in 1947 and opened services to several European countries, including the United Kingdom, as well as to US cities.

From 1954, the North Stars were gradually replaced by longer-range Lockheed Super Constellations: fourteen of these aircraft operated transatlantic routes reaching as far as Vienna, as well as Bermuda and Caribbean destinations such as Jamaica and Trinidad. The last North Star was withdrawn on 13 June 1961. The last North Star was sold in 1961. The final Super Constellations were retired in 1963.
