It is really worth the extra expense to get the advice of a professional tax account. Contact Larry at Pricewaterhouse Coopers in Vancouver. He is doing our Canadian
taxes while we are away in Oz and is very familiar with the process. You don't want to be slapped with a horrendous tax bill in the event you ever come back Canada right? It's better to be SURE than, to get unclear answers.
Anyhow, it's not like any of us on this forum are going to a tax free country like Saudi Arabia. In that case, you would absolutely want to make sure claim yourself as a Non-Resident of Canada.
