DEFOs who started after Jan 1 08 may not bid to HK until they have been at CX 4 years. I did not understand the reasoning they gave, probably cause i was not really paying attention to it. I would not mind going to HK in the future, but not in the immediate future. Go look on the Canadian consulate website, you can overnite in Canada to fly a foreign registered vessel or AC. I talked to the Consulate in SEA and they confirmed that I could indeed commute to YVR and be based there with no visa, but could not live there unless i had a visa.
good luck
