Practical planning for Canadian and Quebec buyers

Canadian mortgage comparison calculator for home buyers

MortgageComparator.ca helps you compare real purchase scenarios before you make an offer. Test different down payments, monthly carrying costs, CMHC insurance outcomes, and Quebec closing costs in one place.

What this calculator helps you answer

Instead of comparing headline rates only, you can compare the full structure of a purchase: lender rates, amortization, term, down-payment strategy, transfer taxes, condo fees, property-specific monthly costs, and price per sqft.

Compare mortgage scenarios

Evaluate multiple lenders and terms side by side to see which option changes your monthly payment and upfront cash the most.

Estimate real home-buying costs

Include CMHC insurance, Quebec welcome tax, municipal and school taxes, condo fees, insurance, and basic rental assumptions.

See and compare prices by sqft

Add sqft for each property and compare the $ / sqft metric directly in the property summaries while you shortlist options.

Mortgage calculator and comparison tool

Use the interactive calculator below to compare up to 20 properties and several mortgage scenarios. It is designed for planning and shortlist decisions, not final lender approval.

Common pitfalls when buying a property

Buyers often focus on the advertised rate and miss the other costs that decide whether a purchase actually works.

Underestimating cash required upfront

Down payment, welcome tax, legal fees, inspection costs, and CMHC-related charges can change affordability before the first monthly payment starts.

Ignoring Quebec and municipal costs

Transfer tax rules, school taxes, condo fees, and insurance can materially change the total monthly burden between neighborhoods and property types.

Comparing rates without comparing structure

A lower rate does not automatically create the best outcome if amortization, insured status, or borrowed down payment change the rest of the file.

Why MortgageComparator.ca exists

This site started as a private diagnostic spreadsheet built while shopping for homes. After other buyers asked for a copy, it became a public tool so more people could pressure-test a purchase with clearer numbers.
