Welcome to Mortgage Library, a plain-English, independent resource about mortgages in Canada. Whether you’re buying your first home, facing a renewal, thinking about refinancing or building a rental portfolio, our goal is simple: help you understand how Canadian mortgages actually work before you sign anything.
Mortgages are one of the biggest financial commitments most people make, yet the rules, the math and the jargon are rarely explained clearly. We want to change that, with real Canadian examples, honest trade-offs and no sales pressure.
What you’ll find here
How we write
- Plain English first. We explain terms when we use them and skip jargon where we can.
- Canadian context. We use Canadian rules, lenders and examples, including the stress test, CMHC insurance and semi-annual compounding.
- Real numbers. Our articles include worked examples, charts and tables so you can see how decisions play out.
- Kept current. Mortgage rules and rates change often, and we review articles as they do.
You can read more in our Editorial Standards, including how we research and how to report a correction.

Who Mortgage Library is for
- First-time buyers figuring out down payments, pre-approval and closing costs.
- Homeowners facing renewal who want to negotiate or compare lenders instead of signing the first offer.
- Owners thinking about refinancing to renovate, consolidate debt or access equity.
- Self-employed borrowers who need to understand how lenders read their tax returns.
- Investors financing rental properties and planning how to keep qualifying as they grow.
Wherever you are in the process, the aim is the same: understand the trade-offs, see the real numbers and walk into every conversation with a lender better prepared.
