What Makes a Canadian Mortgage Different
📐 Semi-Annual Compounding
Your nominal rate gets compounded twice a year, then converted to an equivalent monthly rate for payment purposes — a small but legally mandated difference from monthly compounding used elsewhere.
🛡️ CMHC Default Insurance
Required on any purchase under 20% down, this premium protects the lender and is typically added directly to your mortgage principal rather than paid upfront in cash.
📅 Amortization vs Term
Your rate is only locked for a short term (often 5 years), while the amortization period (often 25 years) is the full payoff timeline used to size your payment.
⚡ Accelerated Payments
Choosing accelerated bi-weekly effectively adds one extra monthly payment a year, shaving years off a 25-year amortization without feeling like a bigger monthly hit.
