Direct answer
On a $500,000 mortgage at 5.00% fixed interest in Canada, your estimated monthly payment is $2,908 per month on a 25-year amortization ($117,019 total 5-year interest) or $2,668 per month on a 30-year amortization. Under the federal Interest Act, Canadian mortgages compound semi-annually (not monthly).

In Canada, down payments under 20% require default insurance from CMHC, Sagen, or Canada Guaranty. The premium is added directly to your mortgage balance:
| Down Payment | Loan-to-Value (LTV) | CMHC Insurance Rate | Total Financed Balance | Monthly Payment (@ 5.0%) |
|---|---|---|---|---|
| $25,000 (5.0% Min) | 95.0% LTV | 4.00% (+$19,000) | $494,000 | $2,873 / mo |
| $50,000 (10.0%) | 90.0% LTV | 3.10% (+$13,950) | $463,950 | $2,698 / mo |
| $75,000 (15.0%) | 85.0% LTV | 2.80% (+$11,900) | $436,900 | $2,541 / mo |
| $100,000 (20.0%) | 80.0% (Conventional) | $0 (No Insurance) | $400,000 | $2,326 / mo |
Under OSFI Guideline B-20, Canadian federally regulated lenders must qualify borrowers at the Minimum Qualifying Rate (MQR) - the greater of the contract rate + 2.00% or 5.25%:
| Contract Interest Rate | OSFI Stress Test Rate | Stress Test Monthly Payment | Estimated Gross Income Required |
|---|---|---|---|
| 4.00% Fixed | 6.00% MQR | $3,199 / mo | ~$98,500 / year |
| 4.50% Fixed | 6.50% MQR | $3,349 / mo | ~$103,100 / year |
| 5.00% Fixed (Current) | 7.00% MQR | $3,502 / mo | ~$107,800 / year |
| 5.50% Fixed | 7.50% MQR | $3,658 / mo | ~$112,600 / year |
* Income estimates use the shipped UseCOS engine's principal-and-interest stress-test payment divided by a 39% GDS ratio. They do not include property tax, heating, condo fees, other debt, lender policy overlays, or insurer-specific rules.
All Canadian mortgage payments are computed using semi-annual compounding as mandated by Section 6 of the federal Interest Act(PMT = [P × i] / [1 - (1 + i)^(-n)] where i = (1 + r/2)^(2/12) - 1). CMHC insurance premium calculations comply with official Canada Mortgage and Housing Corporation underwriting schedules. Stress-test thresholds conform to the Office of the Superintendent of Financial Institutions (OSFI) Guideline B-20.
