I will not be able to until I apply for a new permit then apply for the PRA and wait 2-3 years and if they clear the origin to be acceptable to import from. Similar to the USDA regulations except you do not get the plant material, you do not quarantine it (although who knows they may change that too) you just wait and see if they say yes or no. If I am so inclined to order again it will cost more and take more time. I am already trying to reduce numbers of trees so there is a good chance that I will not re apply especially with no certainty that I will be able to import from them.
With all honesty, Jon has imported from Europe with trees that are in Qaurantine or open, so it would seem to be easier for me to wait for their quarantine to be finished and then import from them from the us when they take cuttings, since he is a nursery that can issue a phytosanitary certificate, when the restriction of him shipping to Canada is up, it will still work out cheaper and more certain than me waiting for my PRA to be processed and validated (if at all).
