"The only conclusion to reach is that incomes are not being reported, says Mr. Wozny. A segment of the population is effectively subsidizing a group that refuses to pay its taxes." That is true to an extent but it is also the case that house price inflation has superseded the incomes of those that originally purchased a once affordable house. Case in point: A family purchases their house in Kerrisdale in 1970 for around $45, 000. They could sell it today for around $5m (a tear down no less). Their income has never been crazy and they worked hard to afford what was then a moderately expensive house and live in what is now a stratospherically expensive house. But their income tax report would be wildly out of line with the value of the house - they could never afford the same thing today. So, by all means nail people who are scamming the system, but there are many who have simply benefited by going about their business and using their house as it was meant to be used: as a home.
