Mortgage Guides for Canada: Lender Policy, Rates and the Arithmetic, Explained Properly
Mortgage rates are the easy part and everyone publishes them. This is the rest: what each lender actually approves, how the arithmetic works, and which of the ten situations you are in.
Streams
Your situation
The ten cases where the advertised rate does not apply to you, and what actually decides the answer.
Lender policy
What each lender will and will not approve — how it reads income, what it wants documented, who it is not for. No other Canadian rate site publishes this.
The numbers
How the arithmetic works and where the figures come from: semi-annual compounding, the stress test, land transfer tax by jurisdiction.
Market commentary
What moved rates this month and what it means for a renewal in the next ninety days.
The ten cases where the advertised rate does not apply
A salaried buyer with 20% down and clean credit gets roughly what the board says. These do not, and the gap between the advertised rate and the real one is where the money is.
What each lender will actually approve
77 profiles, written for a borrower rather than a broker. How the lender reads employment, self-employed, commission, rental and pension income; what it typically wants documented; and who it is plainly not for.
How the arithmetic works, and where the figures come from
Semi-annual compounding
Canadian mortgages compound semi-annually, not in advance — i = (1 + j/2)^(2/n) − 1. Most free calculators on the internet use the American monthly formula and quietly overstate every payment they produce. On a $500,000 mortgage at 5.00% over 25 years the Canadian payment is $2,908.02; the American formula returns $2,922.95.
Fifteen dollars a month, on pages that look authoritative. The payment calculator shows its working.
The stress test
You qualify at the greater of your contract rate plus two percentage points, or 5.25%. The affordability calculator shows GDS and TDS separately, because which of the two is binding tells you what to fix.
Land transfer tax
All 13 provinces and territories plus Toronto, Montreal and Halifax. Every rule carries its effective date and a link to the government page it was read from, checked 22 August 2026. Anything we could not confirm renders a visible caution rather than a confident number — Nunavut is currently flagged, because the territorial legislation site blocks automated access.
Where a figure comes from, how often it is re-checked, and what happens when it cannot be verified.

Now publishing
What moved rates this month, what the Bank of Canada actually said rather than what the headline said it said, and what it means for a renewal landing in the next ninety days — written by the rate desk, published on a schedule.
Mortgage questions, answered
Is any of this gated?
Every calculator and lender profile is free to use. A free account unlocks the full rate board with the lender behind every rate, saves your application as you go, and powers the Renewal Tracker.
Who writes it?
The rate desk. Lender policy is compiled from lender documentation and checked against the lender's own published material; tax figures are read off primary government sources with the date of the check printed on the page. Where something could not be confirmed, the page says so rather than presenting it as settled.
Why publish lender qualification policy at all?
Because the rate is the last thing that gets decided and the first thing everyone publishes. Which lender will read your income generously, what it wants documented and what it will treat as an exception decides whether you are approved at all — and it is nowhere on the consumer internet. A borrower who understands that walks into the conversation knowing what they are choosing between.
How often is it updated?
The rate board every two to three business days. Lender profiles when a lender changes a programme or is acquired — three of the profiles were rewritten in the last eighteen months for exactly that reason. Tax tables are re-checked every January, because Quebec indexes annually and municipal rates move with budgets.
