How it's worked out

The premium is a share of the loan set by the loan-to-value: 4.00% above 90%, 3.10% to 90%, 2.80% to 85%, 2.40% to 80%, and lower below that. An amortization over 25 years, which first-time buyers and new builds are allowed, adds 0.20%.

The premium is added to the mortgage, so you pay it over time. The sales tax on it is not: Ontario charges 8%, Quebec 9% and Saskatchewan 6%, paid when the purchase closes.

Insurance is only available on homes under $1.5 million, owner-occupied, with at least the minimum down payment: 5% of the first $500,000 and 10% of the rest.
