This whole thing started back in 2007 when cmhc,the banks and the gov't all got together to manipulate the economy and line their pockets.
    Drop the interest rates,change the qualifying rules,increase the amortization period,increase cmhc fees and now trying and reel it all back in before everything comes unraveled. 
    They do not want to get caught with thousands of people walking away from their homes and mortgages, and having to dip into their stash (cmhc is crown corporation with a great balance sheet and revenue stream)the govt needs to pay their employees pensions and benefits,the banks need to keep forking out those dividend cheques to the shareholders. 
    And yes we are all as guilty as they are for letting ourselves get sucked in, thinking the pendulum would not swing back.(ok, maybe not all of us)
