💡 Why Does Mortgage Insurance Exist?
Mortgage insurance protects lenders if you default, allowing them to offer mortgages with as little as 5% down. Without it, most lenders would require 20% minimum, pricing many first-time buyers out of the market. The premium is based on risk: higher LTV (lower down payment) = higher premium.
Good news: Premiums are portable - if you switch lenders at renewal, your insurance transfers without paying again, as long as you don't increase your mortgage balance or amortization.

What is mortgage insurance in Canada and when is it required?
Mortgage insurance is required in Canada when you put down less than 20% on a property purchase. It protects lenders if you default on your mortgage. Three companies provide this insurance: CMHC (government-backed), Sagen, and Canada Guaranty. All charge the same premium rates based on your loan-to-value (LTV) ratio.
How much does CMHC mortgage insurance cost?
CMHC premium rates range from 0.60% to 4.00% of your mortgage amount, based on your down payment percentage. For example: 5% down = 4.00% premium; 10% down = 3.10% premium; 15% down = 2.40% premium. A $500,000 mortgage with 10% down would have a $15,500 premium (3.10%), added to your mortgage balance.
What is the difference between default insured, insurable, and uninsured mortgages?
Default Insured (lowest rates): Properties ≤$1.5M, 5-19.99% down, owner-occupied, purchase/new-build, ≤25yr amortization. Insurable (moderate rates): Same property limits but can be rental or refinance. Uninsured (highest rates): 20%+ down, properties >$1.5M, or >25yr amortization. Rate differences typically range from 0.10% to 0.40%.
Can I switch lenders if I have mortgage insurance?
Yes! Mortgage insurance premiums are portable. If you switch lenders at renewal, your insurance transfers without paying a new premium, as long as you maintain the same or lower mortgage balance, don't increase your amortization, and keep the same property. This is called premium portability.
What are the minimum down payment requirements in Canada?
Minimum down payment depends on purchase price: $0-$500k = 5% minimum; $500k-$1.5M = 5% on first $500k plus 10% on remainder; $1.5M+ = 20% minimum (insurance not available). For example, a $750,000 home requires $50,000 down minimum (5% × $500k + 10% × $250k = $25k + $25k).
Do I pay the insurance premium upfront or add it to my mortgage?
The insurance premium is typically added to your mortgage balance, so you finance it over your amortization period rather than paying upfront. This means you'll pay interest on the premium amount over time. For example, a $15,000 premium on a 25-year mortgage costs approximately $90-100/month in your payment.
