Could very well have been a British soldier from the the 49th (West Riding) Infantry Division.
Although under Canadian command, the 49th Infantry Division or "Polar Bears" were mostly from the UK as was the make of the Bren LMG he is holding. Days later they were followed up by the "real" Canadians. We (older) Dutch still hold the Canadians in high regard, but we called the Polar Bears, to much annoyance Canadians. So in every new town they liberated from the Nazi's, they started to sing English songs to show they weren't Canadians.
