Getting a Mortgage in Canada - How Much Can You REALLY Afford? (2025)

How Much Mortgage Can You Afford in Canada? πŸ‘πŸ’°

When you're thinking about buying a home, two key questions always come up:

πŸ”ΉHow much do homes cost?

πŸ”ΉHow much can you afford?

In this guide, we’ll focus on that second question—mortgage affordability—and break down the major components you need to understand to confidently navigate Canada’s real estate financing process.

 


What Affects Your Mortgage Affordability? πŸ§ΎπŸ’‘

Key Factors Lenders Consider

Your ability to afford a mortgage is based on several important criteria:

  • Your income and employment stability

  • Current debts (like car loans or credit cards)

  • The size of your down payment

  • Property value and type

  • Credit score and financial history

  • Ability to pass the mortgage stress test

 

Lenders also consider your Loan-to-Value (LTV) ratio, debt service ratios (GDS/TDS), and whether your mortgage will require default insurance.

 


Understanding the LTV Ratio πŸ“ŠπŸ˜οΈ

The Loan-to-Value (LTV) ratio compares your loan amount to the property’s market value.

Example:
If the home is worth $1,000,000 and your mortgage is $800,000, the LTV is 80%.

This ratio determines if your mortgage will be:

  • βœ… Insured (High-Ratio) – LTV above 80%

  • βœ… Uninsured (Conventional) – LTV at or below 80%

 

Your LTV also affects your interest rate, insurance requirements, and mortgage term options.

 


Debt Ratios: GDS vs. TDS πŸ’³πŸ“ˆ

What They Measure

Lenders use two main ratios to assess how much you can afford:

  • Gross Debt Service (GDS) – mortgage + property taxes + heat + ½ strata (if applicable)

  • Total Debt Service (TDS) – GDS + all other debts (loans, credit cards, etc.)

 

In most cases:

  • GDS should not exceed 39% of your gross income

  • TDS should not exceed 44%

 

Let’s break it down with an example πŸ‘‡

 


Mortgage Affordability Example πŸ”

For a household earning $100,000 per year:

  • GDS = $100,000 x 0.39 ÷ 12 = $3,250/month

  • TDS = $100,000 x 0.44 ÷ 12 = $3,666/month

  • Difference = $416/month in allowable outside debt payments

 

This means you can spend $3,250/month on your mortgage, property taxes, heating, and ½ strata fees—and still carry up to $416/month in other debts.

 


The Mortgage Stress Test πŸ˜°πŸ“‰

To qualify for a mortgage in Canada, you must pass the federal Mortgage Stress Test.

You must show you can handle payments at the greater of:

  • Your contract rate + 2%, or

  • 5.25% (current benchmark)

 

Example:
If your actual rate is 4%, you must qualify as if the rate is 6%.
If your actual rate is 1.5%, you still must qualify at 5.25%.

 


What Is Mortgage Default Insurance? πŸ›‘οΈπŸ 

If you put down less than 20%, mortgage default insurance is mandatory. It protects the lender in case of default.

Three main insurers in Canada:

  • CMHC

  • Sagen

  • Canada Guaranty

 

You don’t choose your insurer—it’s assigned by your lender. Premiums typically range from 2.8% to 4% of your mortgage and are added to your loan.

βœ… Fun Fact: The lowest mortgage rates are usually reserved for insured buyers since they represent less risk to the lender.

 


Insured vs. Insurable vs. Conventional Mortgages πŸ§ΎπŸ”

Here’s a breakdown:

  • Insured – Less than 20% down, primary residence under $1M, amortization up to 25 years

  • Insurable – 20%+ down, property still under $1M, up to 25-year amortization

  • Uninsured/Conventional – 20%+ down OR purchase price over $1M OR rentals/refinances

 

Banks often give slightly higher rates for uninsured mortgages because of the higher risk.

 


Why You Should Get Pre-Approved First πŸ“πŸ”

Before you start home shopping, speak with a mortgage broker (or your bank) to get a fully underwritten pre-approval.

Here’s why:

  • βœ”οΈ You’ll know exactly how much you can afford

  • βœ”οΈ You’ll move faster when you find the right home—crucial in a competitive market

  • βœ”οΈ The broker will already have your documents, speeding up final approval ⏱️
