Ottawa homebuyers in 2026 are often surprised to learn the minimum down payment rules are more nuanced than the simple '20% rule' they've heard from family members who bought decades ago. Federal mortgage regulations set out a sliding scale that affects how much you actually need to get into the market.
Canada's Minimum Down Payment Rules
As of 2026, the federal rules require a minimum 5% down on the first $500,000 of a home's purchase price, and 10% on the portion between $500,000 and $999,999. Homes at $1 million or more require a full 20% minimum down payment. For Ottawa's benchmark price of around $685,000, the minimum down payment calculates to: 5% of $500,000 ($25,000) plus 10% of $185,000 ($18,500), a total of $43,500, or roughly 6.3% of the purchase price.
CMHC Mortgage Insurance Premiums
Any purchase with less than 20% down requires Canada Mortgage and Housing Corporation (CMHC) mortgage default insurance. The premium is added to your mortgage principal. At 10–14.99% down on a $685,000 Ottawa home, the CMHC premium is 3.1% of the insured loan amount, roughly $19,800 added to your mortgage. At 5–9.99% down, the premium rises to 4.0%. This is a real cost to factor into your planning.
The 20% Advantage
Putting 20% down ($137,000 on a $685,000 Ottawa home) eliminates CMHC insurance entirely, lowers your monthly payments, and gives you access to better mortgage products including some lender-specific deals. Many Ottawa buyers use a combination of savings, gifts from family (which lenders require to be documented), and First Home Savings Account (FHSA) funds to reach 20%.
Government Programs Available to Ottawa Buyers
The FHSA, introduced in 2023, allows first-time buyers to contribute up to $8,000 per year ($40,000 lifetime) in tax-deductible contributions. Withdrawals for a qualifying home purchase are tax-free, making it one of the most powerful savings tools available. The Home Buyers' Plan (HBP) lets you withdraw up to $60,000 from your RRSP (increased in 2024), and the First-Time Home Buyer Incentive has wound down. Ottawa buyers should also check for Ontario's Land Transfer Tax refund of up to $4,000 for first-time buyers.
How Long Does It Take to Save in Ottawa?
At the median household income in Ottawa of approximately $115,000 and a savings rate of 20%, reaching 10% down on a $685,000 home takes roughly three years. Many buyers accelerate this by doubling up on FHSA and RRSP contributions in their late twenties.
Practical Takeaway
The minimum gets you in the door, but more down means less interest paid over the life of the loan and more breathing room if Ottawa values soften. Work with a mortgage broker, not just your bank, to model the exact tradeoffs for your income and savings position.
