Mortgage insurance calculator

Make the insurance premium visible before it sneaks into the mortgage.

High-ratio buyers often see the monthly payment first and only later realize how much of the balance is actually the default-insurance premium. This page isolates that piece.

Built around CMHC-style loan-to-value premium tiers.
Ontario premium tax is shown when Ontario is selected.
Useful when comparing 10%, 15%, and 20% down scenarios.

Premium-tax handling is explicitly Ontario-first in v1.
The calculator estimates the premium and tax, then rolls the premium into the mortgage total.
