DTI is one factor lenders consider. Credit score, employment stability, and down payment also affect approval. Most Canadian lenders cap TDS at 44% for insured mortgages.
What debt-to-income ratio do Canadian lenders want?
Canadian lenders use two ratios. Gross Debt Service (GDS) is your housing costs — mortgage payment, property tax, heating and half of condo fees — divided by gross income. Total Debt Service (TDS) adds every other debt payment: car loans, student loans, credit card minimums and lines of credit.
For insured mortgages, the limits are a GDS of 39% and a TDS of 44%. Lenders calculate mortgage payments at the stress-test rate, not your contract rate, so your real qualifying ratios are higher than the payment you'll actually make.
Personal-loan lenders look mainly at TDS. Under about 36% is generally comfortable; above 44% approvals get harder and rates rise. Paying off a small card or car loan before applying is often the fastest way to lower your ratio.
Common questions
- Is DTI based on gross or net income?
- Gross income — your pay before tax and deductions.
- Do credit card balances count?
- Yes. Lenders usually count 3% of the outstanding balance as the monthly payment, even if your minimum is lower.
