History / Biographical
Suffield, Alberta, is situated approximately 40km northwest of Medicine Hat, Alberta. A few "large explosive events" (100 to 500 tons) were conducted at the Defence Research Board's (DRB) Suffield Experimental Station in the 1960s. On 19 January 1961, Medicine Hat citizens felt tremors in the community as a result of five tons of TNT being detonated at the station. The station director attributed this anomaly to freak atmospheric and weather conditions. At the time the DRB was testing the effects of shock waves on military equipment.
In July 1964, the Suffield Experimental Station detonated 30,600 blocks of TNT - 500 tons - to test the largest, non-nuclear, non-confined, surface blast. Placed in various sections radiating from ground zero to test the effects of the blast were targets, dummy-men, miscellaneous instruments, mines, model ships, nose cones, repirators, vehicles, subterranean chambers, shelters, tunnels, foxholes, and trenches. Several hundred people were expected to observe the blast, including 80 "official observers" and a VIP party of military and research personnel from Canada, the United States, and Britain.

On 23 September 1940, McGuinness was seriously injured in a naval accident when his ship ran aground; McGuinness’ leg was broken when the ship’s tow cable snapped and he spent the next 11 months convalescing at Camp Hill Hospital in Halifax, Nova Scotia. While in hospital McGuinness contracted scarlet fever and diphtheria and developed osteomyelitis as a complication of his femur facture. McGuinness returned to Winnipeg to continue his convalescence at Deer Lodge Hospital and was ultimately discharged from the navy in 1941.
