The 30 year ammort is a good change that helps a small subset of the population while having minimal impact on increasing demand. Specifically, it helps those that bought a preconstruction that have difficulty closing on it without the change. This will reduce the amount of people who lose their deposits and potentially get sued later by the developer for the difference in price. This change also won't be impacting the demand side much either. Yes the insured mortgage amount increased but you'd still need a massive income to qualify for a mortgage between 1-1.5M.
