How Lenders in Ontario Look at Your Debt

Mortgage lenders don’t automatically reject you for having debt. Instead, they evaluate how manageable your debt is relative to your income.

The Two Key Ratios That Matter

1. Gross Debt Service (GDS)

GDS measures how much of your income goes toward:

• Mortgage payment

• Property taxes

• Heating costs

• 50% of condo fees (if applicable)

Most lenders prefer GDS under 39%.

2. Total Debt Service (TDS)

TDS includes everything in GDS plus:

• Student loans

• Car loans or leases

• Credit card payments

• Lines of credit

Most lenders cap TDS at 44%.

Can I Buy a Home with Student Loans in Ontario?

Yes—student loans are very common among first-time buyers.

How Student Loans Are Calculated

• Lenders look at your monthly payment, not the total balance

• Government student loans are often treated more favorably

• If payments are low, the impact on approval is minimal

Pro Tip for Toronto Buyers

If your student loan is:

• In good standing

• On a fixed repayment plan

• Paid on time

…it usually does NOT stop you from qualifying.

What About Car Loans or Leases?

Car payments affect mortgages more than student loans because they’re usually higher monthly obligations.

How Car Payments Impact Mortgage Approval

• Monthly payment is fully counted in TDS

• Leases are treated the same as loans

• A high car payment can reduce your buying power significantly

Example (Toronto & GTA Context)

• Monthly income: $8,000

• Car payment: $650

• Student loan: $250

That’s $900/month already working against your mortgage qualification.

👉 This is why planning matters.

How Much House Can You Afford with Existing Debt?

There’s no one-size-fits-all answer—but here’s a general guideline for Ontario buyers:

You can still buy a home if:

• Your income comfortably supports debt ratios

• You have good credit (680+ preferred)

• You have stable employment

• Your down payment meets minimum requirements

Smart Strategies to Qualify with Student Loans or Car Payments

1. Pay Down High-Interest Debt First

Credit cards hurt more than student loans.

2. Reduce or Eliminate Car Payments

• Pay off the balance

• Switch to a lower payment

• Delay a new vehicle purchase before buying a home

3. Increase Your Down Payment

A higher down payment can:

• Improve approval chances

• Access better rates

• Reduce monthly mortgage payments

Common Questions (FAQ)

Will lenders deny me just because I have student loans?

No. Most buyers in Ontario have some form of debt.

Should I pay off my student loan before buying?

Not always. Sometimes keeping cash for a down payment is smarter.

Can I qualify with both car payments and student loans?

Yes—if your income supports it and ratios stay within limits.

Final Thoughts: Debt Doesn’t Disqualify You—Poor Planning Does

Having student loans or car payments does not mean you can’t buy a home in Ontario. It simply means your mortgage needs to be structured properly.

With the right strategy, many Toronto & GTA buyers successfully purchase homes every year—even with existing debt.
