Answer: Thank you. - The allegiance that I corrected it to was the 'British Empire', not the UK. The "Allegiance" category in this section applies to Currie's military career, which his WW1 service was the centerpiece of. That conflict was a clash between the British Empire & the German Empire, not Canada vs Germany. Canada declared war on the German Empire in 1914 as a integral part of the British Empire which was threatened as a whole, not as an independent country in isolation. Currie in 1914 would have regarded himself as defending the British Empire, not Canada in isolation, which was under no individual threat from Germany in the least. 

I understand the enthusiasm for Canadian patriotism, but it doesn't really make historical sense to use allegiance to Canada in this context, & it's a mistake to take contemporary sentiments & backdate them onto the past like this, where sentiment was different in these matters.

It would make sense to put military allegiance to the British Empire with that symbol for Currie's martial career, & the Canuck Red Ensign  (great flag, which should be re-introduced today imo, by the way) next to his nationality or birthplace, but putting military allegiance to Canada in the context of WW1 doesn't make contemporary historical sense?
