The Canadian Consumer Tax Index reveals that there has been a dramatic increase in the average familys tax bill from 1961 to 2012. Among those factors is a sizeable increase in incomes over the period: 1,382 percent since 1961. Even with no changes in tax rates, growth in family income alone would have produced an increase in the tax bill from $1,675 in 1961 to $24,828 in 2012.
