What a $450K 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 $2,335 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% ($2,446 a month). Every 1 percentage point on the fixed rate changes the payment by about $258 a month.
The top of the flat-5% zone. Up to exactly $500,000 the minimum down payment is a flat 5%, so a $450,000 home needs $22,500. One dollar over $500,000 and the 10% tier begins, which is why many listings cluster just under that line. The house is 32% below CREA’s September 2026 national average of $666,538.
Down payment and CMHC insurance on a $450,000 house
The minimum down payment on a $450,000 house is $22,500 (5.0%). 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.

Gold = minimum down payment. Red sliver = the CMHC premium, which is added to the mortgage rather than paid in cash.
Ontario adds 8% sales tax ($1,368), Quebec adds 9% sales tax ($1,539), Saskatchewan adds 6% sales tax ($1,026) 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.
What income do you need for a $450,000 house?
Affordability in Canada comes down to two ratios calculated at the qualifying 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 $444,600 mortgage, qualifying at 6.94% means a paper payment of $3,098, so you need about $110,000 a year with no other debts (one earner, or two on about $55,000 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 raises the income needed by about $1,000, because it eats into the 44% TDS limit. See $110,000 salary after tax and $55,000 salary after tax for the full payslip.
The stress test on a $450,000 mortgage
The mortgage stress test is the single biggest reason buyers are approved for less than they hoped. 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 $2,571 payment into a $3,098 test payment; for a 3.95% variable it is 5.95% ($2,831), which is why a variable rate needs about $8,000 less income to qualify.
Qualifying rate = the greater of 5.25% or your contract rate + 2 points. Assumes property tax of 1% of the price, $100/month heating and no other debts.
Monthly vs accelerated bi-weekly payments
Canadian lenders offer monthly, semi-monthly, bi-weekly and weekly payments. Plain bi-weekly ($1,186 × 26) costs the same per year as monthly. Accelerated bi-weekly is half the monthly payment — $1,285 — every two weeks; because there are 26 pay periods you make the equivalent of 13 monthly payments a year, and on this $444,600 mortgage that saves about $53,000 of interest and 3 yrs 6 mo.
Years to pay off at a constant rate. Plain bi-weekly barely changes anything; the “accelerated” versions add one extra monthly payment a year.Mortgage balance by year (rate assumed constant at renewal). The shaded band is the first 5-year term.
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 $154,239, of which $102,771 is interest, and still owe about $393,000 at renewal. If rates are 1 point higher then, the payment on the remaining 20 years would be $2,787. At the 30-year amortization the balance after five years is higher, at $408,000.
25-year amortization at the 4.94% typical 5-year fixed; income needed with no other debts (the $1.5M row uses 20% down).
Try your exact numbers
The Canadian mortgage calculator takes any purchase price, down payment, rate and amortization, and shows CMHC insurance and accelerated bi-weekly payments.
Use your prepayment privileges. Most fixed mortgages let you prepay 10–20% of the original balance each year without penalty. An extra $200 a month on this loan at 4.94% cuts about $48,000 of interest over 25 years.
Plan for renewal, not just today. After the first 5-year term you will still owe about $393,000. Renewal rates could be higher or lower; check what your payment would be at +1 point ($2,829/month at today’s balance).
Watch the 20% line. At 20% down there is no CMHC premium, but uninsured rates are often a little higher. Compare the total cost both ways — sometimes 19% down with insurance is close to 20% down without.
Check the prepayment penalty. Breaking a fixed mortgage early usually costs the greater of three months’ interest or the interest-rate differential (IRD), which can be thousands. Variable mortgages typically charge three months’ interest.
Get pre-approved early. A pre-approval holds a rate (often for 90–120 days) and tells you exactly what the stress test allows. If rates rise before you buy, you keep the held rate; if they fall, ask for the lower one.
