Canada Mortgage Calculator

Every federally regulated lender in Canada applies the same OSFI-mandated framework to calculate your maximum mortgage. Two ratios determine your limit:

Gross Debt Service ratio (GDS): your housing costs, including mortgage payment, property taxes, condo fees if applicable, and heat, must not exceed 39% of gross monthly income.

Total Debt Service ratio (TDS): all your debt payments combined, including the housing costs above plus car loans, student debt, credit cards, and other obligations, must not exceed 44% of gross monthly income.

Both ratios are calculated at the stress test rate, not your actual contract rate.

All borrowers at federally regulated lenders must qualify at the higher of:

Their contract rate plus 2%, or

5.25%

If you receive a rate of 4.09%, you qualify at 6.09%. If you receive a rate of 3.50%, you qualify at 5.25%. This test typically reduces your approved mortgage by 15% to 20% compared to qualifying at the actual rate.

The stress test applies to both insured mortgages (under 20% down) and uninsured mortgages (20% or more down) at federally regulated lenders. The one exception is a straight switch at renewal where you move your mortgage to a new lender without increasing the loan amount or amortization.

What determines your maximum mortgage:

Gross income and income stability. The higher your verifiable gross income, the more the GDS and TDS ratios allow. Employment income, self-employment income (average of last two years), rental income (usually at 50% of gross), and investment income all count.

Existing debts. Every $500 in monthly debt payments reduces your maximum mortgage by roughly $50,000 at current rate levels. Pay down consumer debt before applying if your TDS ratio is close to the limit.

Down payment. More down means a smaller loan, lower GDS ratio, and potentially no CMHC premium.

The property itself. Condos with high monthly fees, older homes requiring heating estimates, or properties in markets with high municipal taxes all affect the GDS calculation.

Indicative borrowing figures for 2026:

These figures assume the stress test rate. Use the affordability calculator to get a precise figure based on your income, debts, and target property.

Canada uses tiered minimum down payments based on the purchase price:

Examples:

• $400,000 home: minimum down payment of $20,000 (5%)
• $700,000 home: $25,000 (5% of $500,000) plus $20,000 (10% of $200,000) equals $45,000 minimum
• $1,000,000 home: $25,000 plus $50,000 equals $75,000 minimum (7.5%)
• $1,500,000 home or above: $300,000 minimum (20%)

The $1.5 million insured mortgage cap was raised from $1,000,000 in December 2024, giving buyers in expensive markets like Toronto and Vancouver access to insured mortgages on higher-priced homes for the first time.

Any buyer who puts down less than 20% must purchase mortgage default insurance, by law. CMHC is the largest provider. Sagen (formerly Genworth) and Canada Guaranty also offer it. The insurance protects the lender, not you, if you default.

CMHC insurance premium rates in 2026:

The CMHC premium is added to your mortgage balance, not paid upfront. On a $400,000 mortgage with 5% down, the 4% premium adds $16,000 to your loan balance. You then pay interest on that premium for the life of the mortgage.

Since August 2024, first-time buyers purchasing a newly built home can access a 30-year amortization (up from 25 years for insured mortgages). This lowers your monthly payment by roughly 8% to 10% versus a 25-year amortization and raises the price you can qualify for under the GDS and TDS limits. The property must be newly built (not resale) and you must not have owned a home in any of the previous 4 calendar years.

All other insured mortgage holders remain at a maximum 25-year amortization. Uninsured mortgages (20% or more down) can amortize up to 30 years regardless of buyer type.

The Bank of Canada held its policy rate at 2.25% on September 2, 2026. The Bank continues to balance inflation pressure from tariffs against trade-related economic weakness. Markets now expect one or two additional cuts in late 2026 if economic data supports it.

Current rates as of September 10 to 11, 2026:

The Big Six gap. The difference between broker/direct lender rates and Big Six bank posted rates in Canada can exceed 0.50% to 0.75% on comparable products. Using a mortgage broker who shops across multiple lenders typically saves tens of thousands of dollars over a 25-year amortization.

Fixed vs variable in 2026. The variable rate sits roughly 0.70% to 0.80% below the 5-year fixed. Whether that spread justifies the risk of variable payments depends on your cash flow tolerance and view on Bank of Canada rate decisions. With the BoC holding at 2.25%, variable rate holders are not seeing current cuts flow through immediately.

Use the lender compare tool to see current rates across multiple Canadian lenders for your down payment and amortization scenario.

Fixed-rate mortgage. Your rate and payment stay the same for the term (typically 5 years), regardless of Bank of Canada moves. At the end of the term, you renew at market rates.

Variable-rate mortgage (VRM). Your payment stays fixed but the interest/principal split changes when the prime rate moves. If the prime rate rises, more of your payment goes to interest and less to principal. Your amortization extends unless you trigger a trigger rate provision.

Adjustable-rate mortgage (ARM). Your actual monthly payment adjusts with the prime rate. More payment certainty about principal reduction, less certainty about monthly cash flow.

Open vs closed. Open mortgages allow full prepayment at any time with no penalty. They carry a higher rate. Closed mortgages restrict prepayment but offer lower rates. Most Canadian buyers choose closed mortgages with prepayment privileges.

Prepayment privileges. Most closed mortgages allow you to prepay 10% to 20% of the original principal per year without penalty. You can also increase your payment by 10% to 20% without penalty. Use the extra payment calculator to see how these prepayment rights cut your amortization and total interest.

Canadian closing costs run 1.5% to 4% of the purchase price on top of the down payment. Land transfer tax is the largest variable item and differs dramatically by province.

Core closing costs every Canadian buyer pays:

Land transfer tax by province (2026):

First-time buyer land transfer tax rebates:

• Ontario: up to $4,000 (covering the full tax on purchases up to $368,000)
• Toronto (municipal): up to $4,475 on top of the provincial rebate
• BC: full refund on homes up to $500,000, partial up to $525,000

Full closing cost example: $700,000 purchase in Toronto, first-time buyer:

No, for owner-occupied primary residences in Canada. The mortgage interest deduction does not exist for Canadian homeowners on their primary home.

Mortgage interest is deductible for rental properties, where it counts as a business expense against rental income.

This is a fundamental difference from the US and Netherlands systems. Your gross mortgage payment is your full cost, with no tax relief to reduce the net figure.

Use the salary and tax calculator to model your net monthly position after the mortgage payment.

Canada does not have a single dominant first-time buyer scheme like the US has FHA or the Netherlands has NHG. Several targeted programs exist:

CMHC insurance itself is the primary tool. By accepting a 5% down payment with a 4% insurance premium, it makes homeownership accessible at lower savings levels.

First Home Savings Account (FHSA). First-time buyers can contribute up to $8,000 per year to an FHSA, up to a lifetime limit of $40,000. Contributions are tax-deductible (like RRSP), and withdrawals for a qualifying first home purchase are tax-free (like TFSA). This is the most powerful first-time buyer savings tool Canada has introduced.

RRSP Home Buyers' Plan. First-time buyers can withdraw up to $35,000 from their RRSP tax-free for a home purchase. Couples can each withdraw $35,000, giving up to $70,000 combined. The withdrawal must be repaid over 15 years or it counts as taxable income.

Land transfer tax rebates. As described above, Ontario, Toronto, and BC offer partial or full rebates for first-time buyers.

Provincial and municipal starter loans. Several provinces offer supplemental low-interest or deferred loans to bridge the gap between the minimum down payment and 20%. Availability and terms vary by province and municipality.

Total timeline from accepted offer to closing: 30 to 60 days is typical. Allow more time for new construction.

At the end of your term (typically 5 years), you renew your mortgage. This is Canada's equivalent of Germany's Anschlussfinanzierung. You can renew with your current lender or switch to a new one.

Switching lenders at renewal allows you to shop for the best rate. Most lenders offer full rate comparisons 120 days before your renewal date. If you switch, you do not need to requalify under the stress test for a straight switch that does not increase the loan or extend the amortization.

Breaking your mortgage early triggers a prepayment penalty. For fixed-rate mortgages, the penalty is typically the greater of 3 months' interest or the Interest Rate Differential (IRD), which can reach $15,000 to $30,000 or more on large loans. For variable-rate mortgages, the penalty is usually only 3 months' interest.

Use the refinance calculator to weigh the penalty cost against the interest saving before deciding to break and refinance early.

5% for homes priced at $500,000 or below. 5% on the first $500,000 plus 10% on the amount above $500,000 up to $1,499,999. 20% for homes at $1,500,000 or above.

The stress test requires you to qualify at your contract rate plus 2%, or 5.25%, whichever is higher. It applies at all federally regulated lenders and reduces your effective borrowing capacity by 15% to 20% versus qualifying at the actual rate.

CMHC mortgage default insurance is mandatory for buyers with less than 20% down at federally regulated lenders. The premium runs from 2.80% to 4.00% of the mortgage amount depending on your down payment. You pay it by having it added to your mortgage balance. It protects the lender, not you.

As of September 10, 2026, the best high-ratio 5-year fixed rate from brokers is 4.09%. The best high-ratio 5-year variable rate is 3.30%. Big Six bank rates run 0.50% to 0.75% higher than broker rates on comparable products. The Bank of Canada held its policy rate at 2.25% on September 2, 2026.

No, not on a primary residence. Mortgage interest is deductible only on rental investment properties in Canada.

The FHSA lets first-time buyers contribute up to $8,000 per year, up to $40,000 lifetime. Contributions are tax-deductible. Withdrawals for a qualifying home purchase are fully tax-free. It combines the best features of an RRSP and TFSA in one account specifically for first-home buyers.
