Important assumptions and limitations
The qualifying stress-test rate is the greater of contract rate + 2 percentage points or 5.25%, based on federal mortgage underwriting guidance as of November 2026. 39% GDS and 44% TDS are planning benchmarks, not universal lender thresholds. A 25-year mortgage is assumed with Canadian semiannual compounding, monthly repayment. Minimum down payment: 5% to $500,000, plus 10% for the portion to $1.5 million, or 20% at $1.5 million and above. Standard CMHC insurance premium bands are illustrative and not exhaustive; property tax is a fixed entered estimate rather than a function of home price. Insurance eligibility, provincial insurance-premium taxes, closing costs, credit, verified income, amortization rules and lender-specific treatment are not modeled. The calculator is not a pre-approval. Canada.ca down payments, OSFI stress-test rate, CMHC premiums.
