$800,000 Mortgage in Canada: Here’s the Estimated Monthly Payment

Buying a home is one of the biggest financial steps most Canadians take, and understanding monthly mortgage costs is key to budgeting wisely. For an $800,000 mortgage, your payments depend mainly on the interest rate, amortization period, and payment frequency. As of mid-March 2026, rates have stabilized after earlier cuts, with the Bank of Canada holding its policy rate at 2.25%. This keeps variable options attractive while fixed rates sit in a reasonable range.

Current Mortgage Rate Environment in Canada

The Bank of Canada has paused rate changes, maintaining the overnight rate at 2.25% since late 2025. This influences variable mortgage rates, which often track the prime rate around 4.45% minus a discount. Fixed rates, tied more to bond yields, show some upward pressure from global factors but remain competitive.

Shoppers can find insured 5-year fixed rates starting near 3.89%, while uninsured conventional ones hover a bit higher, often around 4.0% to 4.6% depending on the lender. Variable rates dip as low as 3.35% to 4.1% in many cases. These figures reflect competitive offers from brokers and major banks.

Rates vary by province, credit score, down payment size, and whether the mortgage is insured. Always compare personalized quotes for the most accurate picture.

Standard Assumptions for Calculations

To estimate payments on an $800,000 mortgage, common scenarios use a 25-year amortization, the typical maximum for insured mortgages, or 30 years for uninsured ones. Monthly payments are standard, though bi-weekly or accelerated options can save interest over time.

Here are estimated monthly payments for popular terms:

• 5-year fixed at 3.89%: approximately $4,170
• 5-year fixed at 4.36% (closer to average): approximately $4,380
• 5-year variable at 3.35%: approximately $3,950
• 5-year variable at 4.0%: approximately $4,200

These are principal and interest only, excluding property taxes, insurance, or condo fees. Actual amounts may shift slightly with exact rates and lender specifics.

How Amortization Period Affects Your Payment

The amortization period—the total time to pay off the mortgage—has a big impact. Shorter periods mean higher monthly payments but less interest overall.

For an $800,000 mortgage at around 4.0%:

• 25-year amortization: roughly $4,200 per month
• 30-year amortization: around $3,820 per month (if allowed for uninsured)

Longer amortizations ease monthly cash flow but increase total interest paid. Recent rules allow extended periods in some cases, but most first-time buyers stick to 25 years.

Additional Costs to Factor In

Your total housing expense goes beyond the mortgage payment. Property taxes vary widely by location—often $300 to $800 monthly in urban areas. Home insurance might add $100 to $200. If your down payment was under 20%, CMHC insurance premiums get added to the loan, slightly raising payments.

Maintenance, utilities, and potential rate changes at renewal also matter. For variable mortgages, payments could rise if the prime rate increases later in 2026.

Tips to Manage or Lower Your Payments

Securing the lowest rate possible makes a difference—shopping around through brokers often beats posted bank rates. Consider making extra payments when allowed, as most mortgages permit 10-20% annual prepayments without penalty.

Locking in a fixed rate provides payment certainty, while variable might save money if rates stay low. Pre-approvals help gauge affordability early.

Final Thoughts

An $800,000 mortgage typically means monthly payments in the $3,900 to $4,400 range under current conditions, assuming a solid credit profile and standard terms. This level suits higher-income households or dual earners in many markets. Use online calculators from lenders or the Financial Consumer Agency of Canada for tailored estimates, and speak with a mortgage professional to confirm what’s realistic for your situation.
