When Sunnybrook Military Hospital opened in 1948, each treatment block in the main building was identified by a plaque representing military or places of battle where so much was sacrificed. Although the plaques were removed when Sunnybrook transitioned from a Veterans facility to a fully affiliated academic general hospital in 1966, they were rededicated in 2018. Lancaster Wing is currently called C Wing.
The Avro Lancaster was derived from the unsuccessful twin-engine Avro Manchester bomber that first flew in 1939. The decision was made in late 1940 to replace the two Rolls Royce Vulture engines of the Manchester with four of the more reliable Rolls Royce Merlin (in Canada, Packard Merlin) engines, which had a proven record in the Hurricane and Spitfire fighter designs. The revised design was an immediate success and the Lancaster went on to carry the heaviest individual bomb loads of the Second World War. The Lancaster was manufactured in Canada by Victory Aircraft Ltd. in Malton, Ontario, and 430 Mk 10 versions were built. In post-war use, the Canadian- built Lancasters went on to serve in highly useful roles. Quickly converted into photographic reconnaissance variants for charting and mapping and into maritime patrol versions, the Lancaster soldiered on well into the Cold War era.
