Departed from Hurn Airport, Bournemouth, Hampshire, England on delivery to Trans-Canada Air Lines (TCA) with fleet number '632'.
It was flown by Vickers pilot Captain Allen with an unknown co-pilot.
After refuelling at Prestwick Airport, Ayrshire, Scotland it then flew on to Keflavik Airport, Iceland (743 nautical miles) where it stopped overnight.
4 January 1958
Departed from Keflavik Airport, Iceland to Bluie West 8 (BW8) Airfield, Sondre Stromfjord, Western Greenland (804 nautical miles), Goose Bay Airport, Newfoundland & Labrador, Canada (872 nautical miles), Dorval International Airport, Montreal, Province of Quebec, Canada (810 nautical miles).
BW8 was built during WWII to assist the transfer of military aircraft from North America to Europe and was opened in October 1941.
The cabin seating was installed in Canada, as the seats used by TCA were of American manufacture.
The cabin was fitted out with 44 seats which was a reduction from the original 48 seat specification and provided more leg room.
This was heavily marketed and resulted in a high load factor compared to the 18 seat Douglas DC-3 that it replaced on some routes.

Arrived at Dorval International Airport, Montreal, Province of Quebec, Canada.
31 August 1960
Total time 6,939 hours and 5,891 total landings.
Suffered an accident at Gander, Newfoundland, Canada
18 July 1962
Suffered a landing accident at Gander Airport, Newfoundland, Canada while being flown by Captain William 'Bill' Gwynne. The aircraft was on a service from Dorval, Montreal, Province of Quebec to St John's, Newfoundland via Gander.
Having discovered that the nose undercarriage leg would not extend during the approach the aircraft circled for three hours while attempts were made to get the nose leg to drop which included negative 'G' force maneuvers but to no avail.
Advice was given by both TCA and Vickers-Armstrongs. Captain Gwynne finally made a successful landing on a foam covered runway with the nose undercarriage leg still retracted which resulted in the curling of all four propellers and shockloading of the Dart engines.
Bill had been advised that the outer props would not hit the runway which turned out to be incorrect. The TCA flight manual was subsequently amended.
There were no reported injuries to the 35 passengers and 4 crew on board.
Repaired locally, including replacement Rotol propellers and Rolls-Royce Dart engines and returned to service.
1 June 1964
Transferred to Air Canada due to a corporate name change.
