First of all, let me go back to the non-repatriation policy that was given to the commission by the participating governments. It covers only the First World War and the Second World War. What Canada might wish to do, outside of this two-war period, is entirely up to Canada as a sovereign nation.
Dunn is a very interesting case. The commission, and indeed Canada, commemorates by uniform, not by citizenship. Dunn, in fact, won his VC and is commemorated as a British officer, not a Canadian, so you have a problem there. Is he a Brit or a Canadian, even though he's from Toronto?
The second thing is that from time to time, because the commission has staff there, we have gone in at the request of Canada and provided advice on that particular grave. I am also aware of the Canadian engineer group that went in and did the work some years ago.
