There are loads of importers in the US, not sure about Canada though. I can tell you that there is a lot in Cali. If there is a reputable car Tuner shop in your area, ask them if they can import one for you. Nissan SR20's and RB26's are imported often, pricey, but they are done.
Sometimes an engine surplus place will have them out of the blue.
