The first conversions of the Lancaster bomber to the high-speed long-range transport Lancastrian, were made by Victory Aircraft Ltd in Canada. Trans-Canada Air Lines operated these conversions on behalf of the Canadian government on transatlantic mail and passenger services between Montreal and Prestwick. The Canadian Lancastrians were fitted with Packard-built Rolls-Royce Merlin engines and accommodated ten passengers.
