The Japanese-Canadian community on Mayne Island played a historical role in the island's economics and society from the turn of the 20th century until World War II. The community had close ties to the European-Canadian population throughout the Gulf Islands and was involved in major economic initiatives such as greenhouse farming. In 1941 the Japanese Canadians living on Mayne Island were interned by the government and resettled in New Denver for the duration of World War II. Many of the families would never return to the island after the loss of land and their community. Today, the Japanese Gardens, near Dinner Bay, are dedicated to the memory and legacy of the Mayne Island's Japanese-Canadian community.
