If you are considered a non-resident, you are not required to pay tax. If there are too many 'ties' back to Canada, you can be considered a 'factual resident' and be required to pay tax. However, I can also state that you ARE able to own a home, as long as it is rented at arm's length--to a non-family member through a third party ie property manager. You need to have your accountant file a tax return for you in regards to the rental income, but for the most part once the property taxes, the property manager, the accountant and all other expenses are claimed, you will break even and not be required to pay any income tax.
