Toronto taxes pay for Toronto services. Timmins taxes pay for Timmins services. Of course there are transfers from Ontario, but to think that your taxes fund Toronto - NOT.
Your 'tax rate' is higher than Toronto's. But when you factor in the higher value of homes in Toronto, it is very unlikely that your final tax bill is higher.  Your tax rate is higher because you don't have a large commercial base of properties to tax. Accept that, or you have to move.
