When you evaluate updated Canadian mortgage rules, stretching your amortization timeline might seem like the quickest path to manageable mortgage monthly payments. Opting for extended mortgage amortization reduces your regular cash outflow immediately, which can create valuable room in your monthly budget. At the same time, carrying your loan over three decades significantly increases the total compounding interest you pay to your lender over the life of the debt. You must carefully weigh these immediate cash flow advantages against the long-term borrowing costs to decide if this financing structure truly supports your wealth building strategy.
