How Much Do You Really Need for a Down Payment in Ontario?

One of the biggest myths holding first-time buyers back in Ontario is the belief that you need 20% down before you can even think about buying a home. The reality is very different — and understanding the actual rules could get you into a home years earlier than you expected.

The Minimum Down Payment Rules in Canada

Canada's mortgage rules set the minimum down payment based on the purchase price of the home:

• Homes under $500,000: Minimum 5% down
• Homes between $500,000 and $999,999: 5% on the first $500,000, plus 10% on the portion above $500,000
• Homes $1,000,000 and over: Minimum 20% down (no CMHC insurance available)

For most first-time buyers in smaller Ontario markets — think Hamilton, London, Kingston, or Barrie — a 5% down payment is entirely achievable and gets you into the market right now.

Even in the Greater Toronto Area, where average prices are higher, many buyers qualify under the sliding scale rule. A $750,000 home, for example, requires just $50,000 down (5% of $500,000 = $25,000, plus 10% of $250,000 = $25,000).

What Is CMHC Mortgage Insurance?

When your down payment is less than 20%, your mortgage must be insured through one of Canada's three mortgage default insurers: CMHC (Canada Mortgage and Housing Corporation), Sagen, or Canada Guaranty.

This insurance protects the lender — not you — in the event of default. But it's what makes low-down-payment mortgages possible in Canada, and it's a tool that millions of Canadians have used to get into the market sooner.

How Much Does CMHC Insurance Cost?

The premium is added to your mortgage balance and is calculated as a percentage of your loan amount: 4.00% for 5–9.99% down, 3.10% for 10–14.99% down, and 2.80% for 15–19.99% down.

Example: On a $600,000 home with 5% down ($30,000), your insured mortgage is $570,000. The CMHC premium at 4.00% is $22,800 — added to your mortgage, bringing the total to $592,800. Your monthly payment increases slightly, but you're in the market with $30,000 instead of $120,000.

The Real Cost Comparison: 5% vs. 20% Down

On a $650,000 home: 5% down requires $32,500 upfront (plus ~$24,700 CMHC premium added to the mortgage) with a monthly payment of ~$3,900. 20% down requires $130,000 upfront with a monthly payment of ~$3,150. The difference is about $750/month — but if it takes 5 more years to save that extra $97,500, you may end up paying far more for the same home.

Other Costs to Budget For

First-time buyers in Ontario should also budget for land transfer tax (rebates up to $4,000 available), legal fees ($1,500–$2,500), home inspection ($400–$600), title insurance (~$300–$500), and moving costs. Budget an additional 1.5–2% of the purchase price for closing costs.

How to Build Your Down Payment Faster

First Home Savings Account (FHSA): Contribute up to $8,000 per year (lifetime max $40,000), deduct it from your taxes, and withdraw tax-free for your first home.

RRSP Home Buyers' Plan: Withdraw up to $35,000 from your RRSP tax-free. Couples can access up to $70,000 combined. You have 15 years to repay.

What Lenders Actually Look At

Lenders evaluate your GDS ratio (housing costs should not exceed 39% of gross income), TDS ratio (all debt payments should not exceed 44%), credit score (680+ for best rates), and employment history. The mortgage stress test requires you to qualify at your contract rate plus 2%, or 5.25%, whichever is higher.

The Bottom Line

You don't need 20% to buy a home in Ontario. With 5% down, CMHC insurance, and the right programs in place, homeownership may be closer than you think.
