Why CrystalKey is different
Correct Canadian math
Canadian mortgages compound semi-annually by law — not monthly like in the US. Most calculators get this wrong. Ours correctly converts quoted rates to effective periodic rates using the Interest Act formula.
Every upfront cost included
Down payment is just the start. We calculate CMHC insurance, provincial land transfer tax (all 13 provinces and territories), Toronto's municipal LTT, GST/HST on new builds, and closing costs — all in one place.
Rules updated for 2026
The December 2024 rule changes matter: CMHC insured limit raised to $1.5M, GDS limit raised to 39%, minimum down payment thresholds updated. We track every change so you don't have to.
