What Changes When You Finance a Home Above $1.5 Million in Eastern Ontario

The rules shift the moment you cross the insured mortgage cap, and most buyers find out too late

Eastern Ontario's luxury market, waterfront estates on the Rideau, custom builds outside Kemptville, heritage properties in Merrickville and North Grenville, regularly pushes past the $1.5 million mark. Most buyers moving up from a $700,000 or $900,000 home have never financed above that threshold before, and the mortgage rules change in ways that surprise even experienced buyers. Here is what actually changes, and what to plan for before you write an offer.

The $1.5 Million Line Is Not Arbitrary

Effective December 15, 2024, the federal government raised the insured mortgage price cap to $1,500,000, up from the previous $1 million ceiling. That change opened insured financing, and its lower down payment tiers, to more buyers than before. But the cap is still a hard line. A property priced at $1,500,000 or above is not eligible for mortgage loan insurance through CMHC or the other insurers, regardless of how strong the buyer's financial profile is.

Twenty Percent Down Is the Floor, Not the Target

On a $1.8 million property, 20 percent down is $360,000. That is the minimum a lender will accept, not necessarily the amount that gets you the best rate or terms. Because the loan is uninsured, the lender carries the full risk themselves, and many will look for a stronger down payment, cleaner income documentation, and lower overall debt loads before approving a mortgage well above the insured cap. Buyers who assume 20 percent is simply a formality often find their approved amount, or their rate, is less favourable than they expected.

Qualifying Ratios Still Matter, and Lenders Apply Them More Strictly

CMHC's published guidelines call for a Gross Debt Service ratio of 39 percent or less and a Total Debt Service ratio of 44 percent or less for insured mortgages. Those same benchmarks are commonly used as a starting point for uninsured lending as well, but above $1.5 million, lenders have more discretion and often apply tighter internal standards, particularly for buyers with variable or self-employed income, which is common among the entrepreneurs and business owners who make up a large share of Eastern Ontario's luxury buyer pool.

Rural and Custom Properties Add Another Layer

Many Eastern Ontario luxury properties, particularly custom builds, waterfront estates, and larger acreages, do not have the same volume of direct comparables that a suburban Ottawa luxury condo or infill would have. Appraisals on unique rural properties can come in more conservatively than the negotiated price, which affects how much a lender is willing to finance regardless of the buyer's qualifying ratios. Buyers should budget for the possibility of a financing gap between the purchase price and the appraised value, and structure their offer or their financing plan with that risk in mind.

What This Means If You're Planning a Move Above $1.5 Million

Get pre-approved with a lender experienced in uninsured, above-cap mortgages before you start touring properties in this range. Confirm your 20 percent down payment is liquid and documented, not just available on paper. And if you're looking at a custom or rural property without close comparables, talk to your lender about appraisal risk before you're in a firm offer with a tight financing condition.

Financing above $1.5 million is straightforward once you know the actual rules, but it catches buyers off guard when they assume the same playbook that worked on their first home still applies. If you're considering a move into this range anywhere from Kemptville to the Rideau corridor, Deb Driscoll, Jaime Peca, and Luke Geleynse can walk you through what a specific property will realistically require before you make an offer.
