I think that the high rate of intermarriage is a reflection of our community’s desire to “blend” in with the rest of society. This is a result of being targeted during WWII and the dispersal of our communities to further their assimilation into the Canadian mosaic. Most other ethnic groups still hold onto their community base but the Japanese Canadians mainly living in Powell Street and Steveston became dispersed across the country.
The other factor is one of availability. When my son and daughter were going to school there were not many Japanese Canadians to date and thus this would limit the pool of potential partners.
