Numrich has some Cdn wood, but the last stick I saw had been through India and was DP marked. Perhaps paying them for handselect would do the trick.
There is also E-bay, but then you are paying more than anybody else in the whole world.
Vimy Ridge has the best idea. An ad in the EE, or else keeping an eye on the EE, will net what you are after likely as quick as you would get it form the US. But when I say keep an eye on the EE, that may mean checking it 6 times a day. Enfield stuff does not stay on there for very long.
