PVT Arnold was the Great-Grandfather of the chap from whom I bought the rifle and the rifle was passed down directly from PVT Arnold through the grandfather and Father. It's interesting to note that Arnold, a US citizen born in West Virginia, is listed on the 1916 Canadian census as a farmer living in Calgary and Arnold returned to the US in October 1919 per the US Department of Labor border crossing form. I've requested information from several Canadian War and military museums concerning Arnold and this rifle and will post the results when they are available (on the average 4-6 weeks response time). I found this information about Canadian units retaining their service rifles:
Bought in 1896

I have a very thick file which details the purchasing mission of Colonel Percy Lake, Quarter-Master General, when he went to England in 1896 and bought the Lee-Enfield. Fascinating reading.
As an aside, Canadians who served in the South African War could keep their rifle when they returned. As only the First contingent were "Canadian" troops (paid for by Canada), and the rest were "British" (recruited in Canada but paid by the War Office), I am not sure if they could also keep their rifles. canadiansoldiers.com. This rifle has an excellent bore and I'll shoot it in our next vintage military rifle meet. This rifle has all-matching serial numbers (chamber, bolt and rear sight) and as far as I can determine unmodified by any later improvements and is still in its original configuration.
