Every federally regulated lender in Canada must qualify you at a rate higher than the one on your contract. The test exists so borrowers are not sitting exactly at the edge of affordability when their term comes up for renewal.
The rule
You must qualify at the greater of:
- your contract rate plus two percentage points, or
- the minimum qualifying rate set by the regulator
In practice, at today's rate levels, the contract-plus-two figure is usually the binding one. The regulator reviews the minimum periodically, so confirm the current value rather than assuming.
What it does to the payment you must prove
On a $560,000 mortgage over 25 years, using illustrative contract rates:
| Contract rate | Qualifying rate | Actual payment | Payment you must qualify on |
|---|---|---|---|
| 4.29% | 6.29% | $3,034.41 | $3,680.01 |
| 4.89% | 6.89% | $3,222.01 | $3,884.37 |
| 5.49% | 7.49% | $3,414.93 | $4,093.19 |
At a 4.89% contract rate you would actually pay $3,222.01, but must demonstrate you could carry $3,884.37.
The two ratios behind approval
That qualifying payment feeds two calculations:
- GDS — Gross Debt Service. Housing costs (mortgage principal and interest, property tax, heat, and half of any condo fees) as a share of gross income.
- TDS — Total Debt Service. The same housing costs plus all other debt obligations — car payments, credit card minimums, lines of credit, student loans, and support payments.
Lenders apply maximum thresholds to both, with some flexibility for strong applications. Insured mortgages tend to have tighter limits than uninsured ones.
Where applications usually come unstuck
Almost never the mortgage itself. It is generally TDS, and generally one of these:
- Credit card balances. Lenders count a minimum payment even if you clear the card monthly.
- Vehicle payments. A large car payment can cost you far more in borrowing capacity than the car is worth.
- Unused credit lines. Some lenders count a payment on available credit, not just drawn balances.
- Co-signed debt. If your name is on it, it counts as yours.
How to improve your position
- Clear small consumer debts first. Eliminating a $400 monthly obligation frees materially more borrowing room than the same amount added to your down payment.
- Increase the down payment past twenty per cent. This removes the insurance premium and can open slightly more flexible ratios.
- Leave your credit alone before applying. New accounts and hard enquiries in the months before an application do not help.
- Consider a longer amortisation. It lowers the qualifying payment and improves the ratios, at the cost of more total interest.
Where non-bank lenders fit
Provincially regulated credit unions are not bound by the federal guideline and set their own policy. This does not mean qualification is casual — it means the rules differ. For self-employed applicants and unusual income structures, that difference is sometimes decisive.
