The media often claims that high-income Canadians pay the same or lower taxes than low-income Canadians. Is this a valid claim? Why or why not? I've been asked to compare a Canadian earning $40,000 per year with a Canadian earning $80,000 per year. Would the higher-income Canadian pay the same amount of tax? Twice as much tax? Or more than twice as much tax? I need to explain. I've also been asked to explain why marginal tax rates in Canada are higher than average tax rates.
