Knowing your stated history, I think you may be interested in this.

Most crossed the border and enlisted in little border towns. Bellingham, Washington for many from my area.

Of the 40,000 enlistees, I don't know how many went overseas, in country, but far too many, and because they enlisted in American recruitment centres they are listed as American casualties on the Vietnam War Memorial, even though they be from the sawmill flats of Oliver, B.C. or the wharves of Port Coquitlam.

It's a bit of history lost. Eager recruiters never listed point of origin, just point of enrollment.
