Hello Anon, In Canada there is no way to write off the full costs of your main residence. If you are self employed you can claim a portion of your home as an office you will be able to write off a portion of your home expenses on your taxes. Speak to an Accountant to make sure how much you can claim and if you are eligible. If you have a property that is considered a rental property you can write off 100% of the cost of owning that property against the income you get for rental of that property. We are all hoping that Canada will fall in line with the US regarding the ability to write off your mortgage, property tax etc for your main residence but it is not a law yet. If you or any reader have a question regarding this or any topic please do not hesitate to contact me at any time.
