Buying a home in Canada is not simply a matter of saving a down payment and finding the lowest advertised mortgage rate.
The amount you can actually borrow depends on several rules working together: the minimum down payment, mortgage insurance requirements, the mortgage stress test, debt-service ratios and, for some buyers, the maximum amortization period.
Several major federal mortgage changes introduced in late 2024 remain important in 2026, including the higher $1.5 million insured-mortgage price ceiling and expanded access to 30-year insured mortgages for first-time buyers and purchasers of newly built homes.
For buyers trying to understand what they can realistically afford, these rules matter more than simply looking at the monthly payment shown in an online listing.
How much down payment do you need in 2026?
Canada uses a tiered minimum down-payment system.
For a home priced at $500,000 or less, the minimum down payment is 5%.
For a home priced above $500,000 but below $1.5 million, the minimum is:
5% of the first $500,000 + 10% of the amount above $500,000.
For a home priced at $1.5 million or more, the minimum down payment is 20%. The federal insured-mortgage limit applies only to eligible properties priced below $1.5 million.
A few examples make the rule easier to see:
| Home price | Minimum down payment |
|---|---|
| $450,000 | $22,500 |
| $650,000 | $40,000 |
| $1,200,000 | $95,000 |
| $1,400,000 | $115,000 |
| $1,500,000 | $300,000 |
The jump at $1.5 million is significant.
A $1.4 million purchase can have a minimum down payment of $115,000. But at exactly $1.5 million, a buyer generally needs 20%, or $300,000, because the property is no longer within the standard insured-mortgage price limit.
That distinction can materially affect the price range a buyer targets.
What happens when your down payment is below 20%?
A mortgage with less than 20% down is commonly called a high-ratio mortgage, and mortgage loan insurance is typically required.
The insurance protects the lender, not the homeowner, if the borrower defaults.
People often refer to this as “CMHC insurance,” but CMHC is not the only mortgage insurer in Canada. Lenders can also work with approved private mortgage insurers.
The insurance premium generally depends on the loan-to-value ratio and can usually be added to the mortgage balance rather than paid entirely in cash at closing.
That is important because adding the premium to the mortgage also means paying mortgage interest on that premium over time.
The mortgage stress test is not your actual mortgage rate
One of the most confusing parts of buying a home in Canada is the mortgage stress test.
The stress-test rate is not necessarily the interest rate you will actually pay.
Instead, it is a higher rate used to determine whether your finances could handle a payment increase.
For federally regulated lenders such as major banks, the current qualifying rate is generally the higher of:
your mortgage contract rate + 2 percentage points
or
5.25%.
OSFI continues to set that minimum qualifying rate for uninsured mortgages, and federal mortgage qualification rules use the same basic benchmark for insured mortgages.
For example, if a buyer receives a mortgage offer at 4.25%, the stress-test calculation would generally use:
4.25% + 2% = 6.25%.
Because 6.25% is higher than 5.25%, the borrower would need to demonstrate that they could afford payments calculated at approximately 6.25%.
That does not mean the borrower pays 6.25%. It means the lender uses that higher rate when testing affordability.
Why a lower mortgage rate does not always produce a much larger approval
Suppose mortgage rates fall.
A buyer may expect their maximum mortgage qualification to rise dramatically.
But because the stress test normally remains two percentage points above the negotiated rate once the contract rate is high enough, the qualifying payment can still be considerably larger than the actual mortgage payment.
That is one reason the advertised interest rate and the maximum amount a bank will lend you are two different numbers.
Income, other debts, property taxes, heating expenses, condominium fees and credit profile can all affect the final decision.
What are GDS and TDS ratios?
Mortgage lenders look at how much of a household’s income is already committed to housing and debt.
Two common measurements are:
Gross Debt Service (GDS) — housing-related costs compared with gross income.
Total Debt Service (TDS) — housing costs plus other debt obligations compared with gross income.
CMHC’s insured-mortgage programs generally use maximum ratios of 39% GDS and 44% TDS.
Housing costs used in these calculations can include mortgage principal and interest, property taxes and heating. A portion of condominium fees may also be included.
TDS then adds other obligations such as car loans, credit-card debt, student loans and lines of credit.
However, it is better not to describe 39% and 44% as universal approval guarantees.
Different lenders and mortgage insurers can have their own underwriting policies, and simply being below those figures does not guarantee approval.
A car loan can reduce mortgage qualification more than buyers expect
Imagine two households earning exactly the same annual income.
One has no consumer debt.
The other has a $700 monthly vehicle payment plus revolving credit-card balances.
Even if both have identical down payments, the second household may qualify for a considerably smaller mortgage because those payments increase its TDS ratio.
This is why preparing for a mortgage is not only about building the down payment.
Reducing expensive monthly debt before applying can sometimes improve borrowing capacity more meaningfully than adding a relatively small amount to savings.
Who can get a 30-year insured mortgage in 2026?
Canada’s First Home Savings Account (FHSA) can allow eligible first-time buyers to receive a tax deduction for contributions while making qualifying home-purchase withdrawals tax-free.
For contribution room, deductions and first-time buyer rules, see our FHSA Canada 2026 guide.
Since December 15, 2024, insured mortgages with amortization periods of up to 30 years have been available when the borrower is either:
- a first-time homebuyer, or
- purchasing a newly constructed home.
The program applies to qualifying high loan-to-value insured mortgages.
So a first-time buyer purchasing an eligible resale property can potentially qualify for a 30-year insured mortgage.
A buyer who is not a first-time purchaser may also qualify for the 30-year insured amortization if the property is a qualifying newly constructed home.
This is different from the older rule under which insured mortgages were generally limited to 25-year amortizations, with narrower exceptions.
What counts as a first-time homebuyer?
For this particular federal mortgage measure, the definition is broader than simply “someone who has never owned property.”
The federal government says a borrower may qualify as a first-time buyer if they meet one of several conditions, including never having purchased a home before or not having occupied a home owned by themselves or their current spouse/common-law partner as their principal residence during the relevant previous four-year period.
Special treatment can also apply following the breakdown of a marriage or common-law relationship.
Because definitions can differ slightly among programs, don’t assume that qualifying as a first-time buyer for one federal program automatically answers every FHSA, HBP or mortgage-insurance question.
Does a 30-year mortgage mean the home is cheaper?
No.
A longer amortization usually lowers the required monthly payment because repayment is spread over more years.
But that generally means paying interest for longer.
For example, the same mortgage balance at the same interest rate will usually have a lower monthly payment over 30 years than over 25 years, but the total interest cost can be higher if the mortgage remains outstanding for the full amortization.
So the 30-year option is mainly a cash-flow and qualification tool, not free savings.
A buyer should compare both:
Can I comfortably make the monthly payment?
and
How much will this mortgage cost over time?
The stress test changed for some mortgage renewals
There is another important update for homeowners who already have a mortgage.
OSFI no longer expects its prescribed minimum qualifying rate to be applied when an uninsured mortgage is moved at renewal from one federally regulated lender to another as a qualifying “straight switch.”
To qualify for this treatment, there generally must be no increase to the mortgage balance or remaining contractual amortization period.
Federal policy also allows insured mortgage borrowers to switch lenders at renewal without undergoing another mortgage stress test.
That change matters because homeowners are less likely to become trapped with their existing lender simply because they cannot pass the stress test again at a competing institution.
But it does not mean another lender must automatically approve the mortgage.
The new lender can still assess the application under its underwriting standards, and switching can involve appraisal, registration, legal or other administrative costs.
Refinancing is different from simply switching lenders
This distinction is important.
If you are merely moving the existing mortgage balance to a different lender at renewal without increasing the loan or extending the amortization, you may fall under the straight-switch rules.
But if you want to:
- borrow additional equity,
- consolidate other debts into the mortgage,
- materially extend the amortization, or
- otherwise refinance the loan,
the mortgage may again need to satisfy the applicable qualification rules, including the stress test.
So “no stress test at renewal” should not be interpreted as “no stress test for refinancing.”
First-time buyers should look at the down payment before the mortgage
For many first-time buyers, qualification is only half of the problem.
The other challenge is accumulating the down payment.
Canada’s First Home Savings Account (FHSA) can allow eligible first-time buyers to receive a tax deduction for contributions while making qualifying home-purchase withdrawals tax-free.
We have a separate guide covering contribution room, deductions and first-time buyer rules:
FHSA Canada 2026: Contribution Limits, Tax Deductions & First-Time Home Buyer Rules
Someone planning a home purchase should think about the FHSA and mortgage qualification together rather than treating them as completely separate decisions.
A larger down payment can reduce the mortgage balance, but keeping enough cash for closing expenses and an emergency reserve also matters.
An Alberta example
Suppose a buyer in Alberta is considering a $650,000 home.
The federal minimum down payment calculation would be:
5% of the first $500,000 = $25,000
10% of the remaining $150,000 = $15,000
Minimum down payment = $40,000
That works out to roughly 6.15% of the home’s purchase price.
Because the down payment is below 20%, the mortgage would generally require mortgage loan insurance, assuming the borrower and property otherwise meet the insurance program’s requirements. The borrower would also have to qualify using the applicable stress-test rate.
If that buyer qualifies as a first-time homebuyer, a 30-year insured amortization may also be available.
That illustrates why looking only at “5% down” can be misleading for homes priced above $500,000.
Before getting pre-approved
A useful pre-approval conversation should cover more than the interest rate.
Ask the lender or broker what qualifying rate they used, what property taxes and other housing expenses were assumed, whether your mortgage will be insured or uninsured, what amortization periods you are eligible for, and what happens to the payment if rates change at renewal.
Also compare your realistic purchase budget with the maximum amount a lender offers.
Being approved for a mortgage does not necessarily mean taking the maximum loan is comfortable for your household.
Frequently Asked Questions
What is the mortgage stress-test rate in Canada in 2026?
For federally regulated lenders, the qualifying rate is generally the higher of 5.25% or your mortgage contract rate plus 2 percentage points.
What is the minimum down payment on a $600,000 home?
The calculation is 5% of the first $500,000, or $25,000, plus 10% of the remaining $100,000, or $10,000.
That produces a minimum down payment of $35,000.
Can I buy a $1.4 million home with less than 20% down?
Potentially, yes.
Because eligible insured mortgages can apply to homes priced below $1.5 million, the minimum down payment on a $1.4 million home is $115,000, subject to mortgage-insurance and lender qualification requirements.
What about a $1.5 million home?
At $1.5 million or more, the minimum down payment is generally 20%, meaning at least $300,000 on a $1.5 million purchase.
Can every buyer choose a 30-year insured mortgage?
No.
For insured high-ratio mortgages, the expanded 30-year option applies when the borrower is a qualifying first-time homebuyer or the property is a qualifying new build.
Do I need to pass the stress test when switching lenders at renewal?
A qualifying straight switch may be exempt.
For uninsured mortgages, OSFI’s exemption generally applies when switching between federally regulated institutions without increasing the loan amount or remaining amortization. Insured borrowers also have federal protection allowing lender switching at renewal without another stress test.
Is mortgage default insurance for the homeowner?
No. Mortgage loan insurance protects the lender if the borrower defaults.
