Camp 33 - Petawawa


In December 1914 a Prisoner of War (POW) Internment Camp opened at Camp Petawawa housing 750 German, Austrian and Italian POWs. They occupied various buildings used by the militia in times of peace and were employed in road cutting, timber felling and ground clearing. The Internment Camp closed in May 1916.

In WWII, an anti-Semitic Canada kept Jewish 'enemy aliens' in barbed wire camps



SHERBROOKE, Quebec — The town of Sherbrooke, located about two hours east of Montreal, is a pleasant place to visit, especially in the temperate summer. There is a waterfall, and a promenade around a lake. In a nearby park, walkways have been built through the swamp to give city-dwellers a chance to enjoy birdsong and admire waterlilies. The town's small history museum has recently reopened — with hand sanitizer and masked tour guides.

But nothing in the museum informs visitors about a bizarre part of Sherbrooke's history: a camp where German and Austrian Jews were held as prisoners during World War II.
In 1940, biochemist Reinhart Pariser was a student in his early 20s at the University of Cambridge in England when one day police knocked on his door and gave him 10 minutes to pack, his son, David Pariser, told The Times of Israel.

Their nationality probably was more of concern than their religion.

Another case I know of was in Ceylon under British rule during WW II.  Two German Jews converted to Buddhism when they were teenagers. They became bhikkhus or monks and had been monks for 20 years or more.  While studying and translating Buddhism into English in Ceylon, they were swept up (1940?) with all other Germans and put in the camps for enemy aliens.  They stayed there until 1946.
