"...Canadians who fought in Alaska..." They got issued American helmets because our issue hat was too similar to the Japaneseicon hat. Didn't stop 'blue on blue' casualties though.
"...Canadaicon did use..." Used and adopted aren't the same thing. Our first 25th Brigade troopies raised for Korea were sent Stateside for training on American weapons, but they weren't adopted or used by our Regular Army. Except for the .30 Browning MG. 1st SSF used 'em, of course.
Certainly not used by 2 Div at Dieppe. 50 or so U.S. Rangers were at Dieppe though. The picture, that works just fine, could have been taken anywhere at any time and published as being Dieppe. Despite it being a Canadian Army photo. No indication of what Regiment the troopies were.
"...has the BNP..." British proof mark required on any surplus firearm sold through Englandicon. Nothing to do with Canada.
