In the spring of 1941, RCMP began registering people of Japanese descent along the BC Coast. This was before Pearl Harbor, but Japan had invaded Asia and into the Pacific.
The registration cards were different colours depending on your status
Japanese Nationals — yellow
Naturalized Canadian — pink
Canadian Born – white
All cards included a photo, finger-print and other personal details. They had to be carried at all times. My baachan was still a Japanese National. This recreation of the front and back of her registration card is based on another actual card in the collection at the Nikkei National Museum (NNM 2011.16.5.1)
