The Dominican Embassy in Canada will not provide information on Canada's requirements for its citizens to become non-residents. It will provide information on the Dominican Republic's requirements for residency in the DR. These are two different issues. Becoming a resident in the DR is pretty straightforward, and you need not begin that process from Canada. I don't know if it's wiser or not to do so, but my preference was to initiate it in the DR.
Maintaining accounts in the US is fine because the US allows bank accounts to be held by non-residents. Now you are talking about US regulations, not Canadian.
However, after 9-11, the banks do ask for more personal information-- a deterrent against funding of terrorism is the reasoning. This is true in Canada as well; ie, corporate bank accounts require more proof of identity upon opening.
Gilbert, you absolutely do not have to give up your Canadian passport, nor would you want to. It is one of the more desirable passports in the world. If I had to give it up, I wouldn't be leaving... I certainly would not trade it for a DR passport! All you have to do is visit theCanadian consulate in the DR once every five years to have it renewed.
Because you are a Canadian citizen, you may return to Canada whenever you wish, so of course it isn't a problem to become a resident again whenever you wish... although, if you were to do so within four years (?), the govt might decide that you had NOT permanently left Canada, and it has within its power the right to consider you a resident for tax purposes. Please do your own research on this... I am uncertain of the 'four year' detail, and as I do not plan to return within that time, it was an unimportant detail in my own research.
About driving in Canada-- as long as you hold a valid driver's license from the DR, you can drive in Canada with that driver's license. But be sure to handle the logistics in a timely way. You will need your valid driver's license from Canada to apply for your DR license. So, obviously, do not give up your Canadian one until you have your Dominican one safely in hand.
The next detail is also important, so please read carefully!
Do not assume that the '6 months plus a day' is the determining factor for Canada to decide you are no longer a resident. It isn't.
It is one of the criteria, because if you met all other requirements, and spent 6 months plus a day in Canada, the govt may declare you a resident of Canada.
Please realize that the CCRA has a pretty broad sweep in its power to determine whether or not you are a resident ... not quite as broad a sweep as the US govt, because it does not tax Canadian citizens on worldwide income if they are no longer residents.
As I said previously, you must cut all 'social ties' to Canada, or you may still be considered a resident for tax purposes. The govt does not really care if you actually reside in the DR, and says so on the CCRA website: "residency in another country does not automatically determine non-residency in Canada"... something to that effect.
Clear as mud?
I am in the arts, so am able to do my work anywhere. I put my 'business' on auto-pilot about 10 years ago to spend time writing, but am ramping it up again to ensure that I will be able to live securely in the DR, given this country's lack of infrastructure. My desire--ok, dream-- is to make it big with the writing, so I am more concerned with future 'world wide income'... which is why I'm making this move now. I think it's always better to plan for what you want, not what you don't want.
If you have no assets in Canada, perhaps you can simply leave and that's that. I would be leary of doing so, however, if your worldwide income is substantial. Much better to fill out the forms and make it official. You certainly don't want to find yourself in a future scrap with Canada.
Again, if you do have assets in Canada, I would advise you to seek some paid advice. I am repeating here what Ricktoronto advised me a few months ago with respect to my own concerns. He's also Canadian--as one might gather from the handle--and a straight shooter in his advice, so pay attention!
Good luck with your move. Feel free to ask other questions.
