The BC government in the previous budget is now enabling people that own homes and financially supporting somebody that is 18 years old or younger to defer their property taxes, at the rate of interest of the bank prime rate. Previously only seniors (55 and older) were able to exercise this option.
Essentially homeowners are given the option of borrowing money (the amount of their yearly property taxes) at the prime rate, and will only have to repay this amount when your property is transferred (i.e. you sell the place).
Almost everybody that is financially sophisticated that is eligible to do this should be exercising this option. Getting money at the prime rate outside a mortgage is not that easy, and at the prime rate you can very likely make an investment that would give a higher rate of return.
The trick is making the interest amount tax-deductible, and if you use the deferred property tax amount for income-generation purposes then in theory you should be able to deduct the interest.
