Mortgage payment on a $800,000 house in Canada

What a $800K house costs at today’s mortgage rates

The Bank of Canada raised its policy rate by a quarter point to 2.50% on 28 October 2026 (up from 2.25%), citing inflation of around 3% driven by high energy prices, and the big banks lifted prime to 4.70% the next day. Variable-rate payments follow prime, so a typical variable mortgage at prime − 0.75 (3.95%) now costs $4,068 a month on this loan. Fixed rates track 5-year Government of Canada bond yields instead; the median 5-year fixed among lenders on Ratehub.ca was 4.94% on 2 November 2026, with the cheapest insured offer at 4.44% ($4,263 a month). Every 1 percentage point on the fixed rate changes the payment by about $450 a month.

Around the national average. CREA’s national average sale price was $666,538 in September 2026 (and it forecasts $681,681 for 2026 as a whole), so a $800,000 home is 20% above the typical Canadian sale. The minimum down payment is now blended: 5% of the first $500,000 ($25,000) plus 10% of the remaining $300,000 ($30,000), for $55,000 — 6.9% of the price.

What income do you need for a $800,000 house?

Canadian lenders do not use a simple income multiple; they test your budget at a higher rate. Your gross debt service (GDS) — the stress-tested mortgage payment plus property tax and heating — must be no more than 39% of gross income, and total debt service (TDS), which adds car loans, credit cards and lines of credit, no more than 44%. On a $774,800 mortgage, qualifying at 6.94% means a paper payment of $5,398, so you need about $190,000 a year with no other debts (one earner, or two on about $95,000 each).

The last column shows the real 4.94% payment as a share of a single Ontario earner’s 2026 take-home pay. A $500-a-month car payment would not change the income needed here: housing costs alone reach the 39% GDS limit first, which still leaves about $790 a month of room for other debts under the 44% TDS limit.

Down payment and CMHC insurance on a $800,000 house

The minimum down payment on a $800,000 house is $55,000 (6.9%). Anything below 20% means the mortgage must carry default insurance from CMHC, Sagen or Canada Guaranty; the premium is a percentage of the loan and is usually added to the mortgage. The table compares down payments; the 30-year column assumes you qualify (first-time buyer or new build when insured) and includes the extra 0.20% premium.

Ontario adds 8% sales tax ($2,384), Quebec adds 9% sales tax ($2,682), Saskatchewan adds 6% sales tax ($1,788) on the premium at the minimum down payment, payable in cash at closing — it cannot be added to the mortgage. Moving from the minimum to 10% down cuts the premium rate from 4.0% to 3.1%, and at 20% it disappears.

The stress test on a $800,000 mortgage

You will never pay the stress-test rate, but it decides how much you can borrow. The qualifying rate is the greater of 5.25% or your contract rate plus 2 points. For a 4.94% fixed that is 6.94%, turning a $4,480 payment into a $5,398 test payment; for a 3.95% variable it is 5.95% ($4,934), which is why a variable rate needs about $14,000 less income to qualify.

Monthly vs accelerated bi-weekly payments

Canadian lenders offer monthly, semi-monthly, bi-weekly and weekly payments. Plain bi-weekly ($2,068 × 26) costs the same per year as monthly. Accelerated bi-weekly is half the monthly payment — $2,240 — every two weeks; because there are 26 pay periods you make the equivalent of 13 monthly payments a year, and on this $774,800 mortgage that saves about $92,000 of interest and 3 yrs 6 mo.

After the first 5-year term

Canadian mortgages are renewed every few years, so the rate above is only locked for the term. Over the first five years you would pay $268,791, of which $179,099 is interest, and still owe about $685,000 at renewal. Renewing at 1 point higher would set the payment for the remaining 20 years at $4,856. At the 30-year amortization the balance after five years is higher, at $712,000.
