It shows that the median family income in Canada is $76,000 â generally higher in the west than the east â while the median individual income is just $27,600. That means just as many individuals earn less than $27,600 as earn more. The richest 10 per cent of individuals are making more than $80,400. And the very rich â the 272,600 individuals who make up the top one per cent â are all making more than $191,100. Those people are making an average of $381,300 each, 10 times the average Canadian income of $38,700. The large discrepancy between the median and the average suggests there is a very small percentage of the super-rich.
