What is the minimum down payment?
The minimum down payment needed in Canada is calculated based on the purchase price of a home. This is the required amount that you will put towards your home and is deducted from the home price when determining your total mortgage with the bank. The minimum down payment required depends on the price of your home. The size of your down payment will also impact if you need to purchase mortgage default insurance.
Purchase price is less than $1,500,000
- 5% on first $500,000;
- 10% on amount more than $500,000 less than $1,500,000
Purchase price is more than $1,500,000
- 20% of the purchase price
Minimum down payment example
Let’s calculate the minimum down payment needed to afford a home in Ontario as an example. As of March 2025 the average home price in Ontario was $860,545. Since this home price is less than $1,500,000 we will calculate the minimum down payment with a two step process.
The first $500,000 of the home price will require a minimum down payment of 5% which will be $500,000 X 5% = $25,000.
The portion of purchase price above $500,000 will require a minimum down payment of 20%. We need to first calculate the amount of purchase price in excess of $500,000. This amounts to $860,545 - $500,000 = $360,545 of purchase price that requires a 10% down payment. $360,545 X 10% = $36,055.
We can then add these two amounts together $36,055 + 25,000 = $61,055. Therefore, the minimum down payment for the typical home in Ontario would be $61,055.
Mortgage loan insurance
Mortgage loan insurance is purchased to protect the lender if you are no longer able to make your mortgage payments. If you are putting down a minimum down payment your lender will often request that you purchase this loan insurance. While the cost of mortgage default insurance can be added to your mortgage which will increase the total size of your mortgage, purchasing this insurance will often allow you to secure a more favourable mortgage rate which will help reduce your mortgage payment.
The cost of mortgage insurance is based on the loan to value ratio which can be calculated by dividing the loan needed by the purchase price of the home.
CMHC mortgage loan insurance premiums
These are the mortgage default premiums that would be charged based on the loan-to-value ratio LTV
| Loan-to-Value (LTV) Ratio | % Down Payment | Premium (% of Loan Amount) |
|---|---|---|
| Up to and including 65% | 35% or more | 0.60% |
| More than 65% up to 75% | Less than 35% down to 25% | 1.70% |
| More than 75% up to 80% | Less than 25% down to 20% | 2.40% |
| More than 80% up to 85% | Less than 20% down to 15% | 2.80% |
| More than 85% up to 90% | Less than 15% down to 10% | 3.10% |
| More than 90% up to 95% | Less than 10% down to 5% | 4.00% |
| (Non-Traditional Down Payment) More than 90% up to 95% | Less than 10% down to 5% | 4.50% |
Let’s go over an example on how to calculate the CMHC mortgage default insurance using the typical home price in Ontario above with the minimum down apyment. Since the Ontario home price is $860,545 we are required to have a minimum down payment of $61,055. This leaves us with a mortgage loan of $799,490 which we can use to calculate the loan-to-value ratio.
The loan to value would be $799,490 / $860,545 = 92.91% which falls between 90% and 95% which would mean our premium would be 4% of our loan amount. This means our total premium would be $31,979.60.
