According to a study by the Canadian Centre for Policy Alternatives, Canada's top 1% earners -- families that earn $266,000 or more, paid 30.5% of their income in taxes. Canada's poorest 10% -- families earning less than $13,523 paid 30.7% in taxes.

The full study can be viewed in Eroding Tax Fairness (PDF).

The study proposes some controvertial methods though, such as making capital gains tax the same as income tax.
