Unfortunately, neither of those companies ship live plants to Canada. I don't know about Vancouver Island, but Arabian jasmine is found for sale very frequently in garden shops, flower stores and even groceries in Vancouver. Try calling around. If no where in Nanaimo, surely it can be found in Victoria or perhaps ordered from one of the nurseries in Vancouver.
They tend to sell more of these wonderful plants near easter. You could also check at your local home depot (oddly enough that's where my sister found hers =/). I found mine at a local greenhouse in Edmonton (Ellerslie gift and garden - but I doubt that they ship plants). From what I can tell, they like decent light, humidity and moist soil :) Good luck finding your plant
