Actually, the departure tax thing is somewhat misunderstood by many, from my understanding anyway.
This is how it has been explained to me by the tax specialists at our accounting firms:
In my case, I would dispose of all my assets / business etc...and convert to cash.
Taxes get paid as if I had done just that, and stayed here. Things that are not taxable while living here don't get taxed if I decide to sell and move. Capital gains/ losses are the same on assets whether you liquidate, or decide to keep them in the event that you leave. Cars, personal possessions, etc...things that are not taxable while living here, are also not taxable when sold and moving away. In my case, better to dispose of all assets, pay the taxes and go.
I have a few friends who have made the move - they all tell me the same thing as my accountants.
In any case, I've had enough of this province, especially after this last idiot, Nazi premier in Quebec, and I have had enough of this country, the lousy medical care and 50% personal tax rate. I feel the warmth beckoning! LOL
