Editorial and evidence policy
The rules this site is written under, so you can judge how much weight to give any page on it — including the decision, on several topics, not to publish a number.
How does HomeCosts.ca decide what to publish?
Every figure must trace to an official Canadian source that we link and date, or to arithmetic the page shows in full. Where a cost is genuinely address-specific we publish the method and the authority to confirm with, rather than a national average. We do not publish testimonials, ratings, usage counts or guarantees, and we remove claims we cannot verify.

The rules, in full
- No invented numbers
- We do not publish an average, a rate, or a premium unless an official source states it and we can link that source. Where a figure is genuinely address-specific — property tax, insurance, land transfer tax — we publish the method and the authority instead of a national average.
- Every calculator shows its formula
- Each tool exposes the arithmetic it used, the assumptions behind it, and a plain-language note on what the estimate cannot establish. Prefilled values are labelled as illustrative editable examples, never as current market rates.
- Jurisdiction is stated, not implied
- Canadian home costs are governed provincially and municipally. Pages state which jurisdiction the guidance applies to and link the provincial or municipal authority rather than generalising across the country.
- Sources are dated
- External references carry a source-link-checked date. If a rule changes between reviews, the official page is authoritative and this site is not.
- No testimonials, ratings or usage claims
- We do not publish reviews, user counts, success statistics or guarantees. Nothing on this site is presented as social proof.
- Advice boundaries are explicit
- HomeCosts.ca is a planning resource. It is not mortgage, legal, tax, insurance or engineering advice, and it does not replace a lender's commitment, a lawyer's opinion, an inspection, or an insurer's quote.
- No login, no tracking of your inputs
- The calculators run in your browser. Figures you enter are not required to be submitted anywhere to get a result, and there is no account to create.
- Corrections are welcome and acted on
- If a figure, source link or method on this site is wrong or out of date, tell us and we will correct or remove it. Removal is preferred over leaving an unverifiable claim in place.
Review cycle
Pages carry a review date. Cost pages that depend on statutory rules — land transfer tax, mortgage insurance thresholds, registered account limits — are re-checked against the official source when a page is edited and at least annually. Where a review finds a source has moved or a rule has changed, the page is updated or the claim is removed rather than left in place with a caveat. The methodology behind each calculator is set out on the sources and methodology page.
