I whipped this map up for a reader researching his father earlier today and thought I would share. The image shows the layout of the internment Camp at Farnham, Quebec overlaid on some modern satellite imagery from Google.
Camp A, as it was initially known, opened in October 1940 and initially held civilian internees and refugees from the United Kingdom. The camp closed temporarily in January 1942 but reopened in April and was used to hold Enemy Merchant Seamen (EMS). In late 1942, the EMS were transferred to Sherbrooke and replaced by German combatant officers and a smaller number of Other-Ranks, serving as the officers’ servants and orderlies. It once again closed briefly in June 1943 before re-opening again as an officers’ camp in September 1944. The camp then remained open until June 1946.
Like most of Canada’s internment camps, the buildings were salvaged and torn down, the barbed-wire fences removed, and the guard towers dismantled. Today, the site is occupied by a Water Treatment Station, a gas station and Tim Hortons, and a Fire Station. For those interested, here is a link to the location.

Thanks Michael – that’s very interesting for us and for Richard Essberger (Richard Essberger )
Fairly sure my father in law Rolf Schultze actually helped to build the original Camp 40 — when they arrived, the camp was only part complete, there was a shortage of civilian workers who were building it, and winter was coming on fast ! It seems that some sort of mutual deal was done to allow the internees to help complete the buildings.
Best wishes, hope all is going well, and do keep in touch.
