Condo vs House Calculator Canada

What lenders actually count from your condo fee — and what they don't

For a CMHC-insured mortgage, the rule is exact: 50% of your monthly condominium fees must be included in both your Gross Debt Service (GDS) and Total Debt Service (TDS) ratio calculations. A house has no equivalent line item — its ongoing maintenance never enters the lender's math at all, which is why two properties with identical monthly carrying costs on paper can qualify very differently once one of them is a condo.

CMHC's own qualification ceilings for insured homeowner loans are GDS at or below 39% and TDS at or below 44% of gross household income, per its general requirements page. A condo fee doesn't change those ceilings — it just consumes room inside them, at half its face value rather than the full amount, and only for insured mortgages specifically; an individual uninsured lender's own underwriting rules for condo-fee treatment are not published by CMHC and are not modelled here.

The reserve fund is the real difference between a condo roof and a house roof

A house owner pays for a new roof out of pocket, on their own schedule. A condo corporation instead maintains a reserve fund — Ontario's Condominium Authority describes it as "a mandatory bank account used to pay for major repairs and replacements of common elements and assets," funded through your monthly fee rather than a surprise bill. Ontario requires a first funding study within a year of registration and updated studies at least every three years after that, so the contribution built into your fee is periodically re-checked against the building's actual repair timeline.

In British Columbia, strata corporations must annually put a minimum of 10% of the total operating-fund budget into the contingency reserve fund, a rule that has applied since November 1, 2023. There is no exemption that lets a well-funded strata stop this 10% contribution once the reserve reaches some threshold of the operating budget — the government's own page ties a commonly-cited "25%" figure to a separate rule for owner-developer contributions on brand-new stratas, not to any stop-contributing exemption for an established building. If a strata's reserve fund looks thin relative to its building's age, that 10% floor is the only backstop; it is not a guarantee the fund is actually adequate.

A house buyer skips all of this — and also skips any collective decision-making about when the roof gets replaced. Compare the ongoing math for both scenarios in the condo fee affordability calculator.

Condo and house insurance are not the same product

A house buyer typically insures under one policy. A condo owner needs two, per the Insurance Bureau of Canada: the condo corporation's own policy, which covers the building itself and common property — hallways, stairs, the roof, pools, garages, driveways — and a separate unit owner's policy, which covers personal property, personal liability, and any upgrades or improvements made inside the unit. Skip the second policy and a condo owner has no coverage at all for their own contents or liability, even though the building is insured.

IBC's coverage-level structure — Comprehensive, Basic/Named Perils, Broad, and No Frills — applies to both a house and a condo unit policy, and flood, earthquake, and sewer backup are typically optional add-ons on either one, not included by default even under Comprehensive coverage. Neither IBC nor any other source in this registry publishes an average premium figure for condo versus house coverage — do not treat any specific annual dollar premium comparison between the two as an official statistic.

A new condo purchase in Ontario comes with a right a house purchase never does

Under Ontario's Condominium Act, 1998, s.73, a purchaser who receives the developer's disclosure statement and the condominium guide may rescind the agreement of purchase and sale before accepting a deed — written notice must reach the declarant within 10 days of the latest of receiving the disclosure statement, the condominium guide, or the fully-executed agreement. If the buyer rescinds, the declarant must promptly refund all money received, without penalty, plus interest at the prescribed rate.

This applies to a new unit bought from a developer — not a resale, and not a house purchase of any kind. A freehold house buyer has no statutory cooling-off window once an agreement is signed (outside separately-negotiated conditions), so the built-in protection exists on exactly one side of this comparison.

The house side of the comparison has its own cost pressure — construction inflation

A house owner's maintenance budget rides on the same input costs as new construction. Statistics Canada's Building construction price indexes for the second quarter of 2026 show residential building construction costs up 0.5% nationally quarter over quarter, with sharp regional variation: Québec city +2.6%, Montréal +2.5%, Halifax +2.1%, Calgary -0.1%, Vancouver -0.2%, and Toronto -0.8%. This is a price-index change in input costs, not a dollar-per-square-foot renovation estimate — but it is the direction a house owner's own repair and renovation bills are moving, city by city, while a condo owner's exposure to the same input costs is smoothed through the reserve fund and the monthly fee instead of hitting all at once.

Neither Statistics Canada, CMHC nor any other government source in this registry publishes a verified comparison of condo versus house price appreciation by Canadian city — a figure often quoted in secondary sources without a citable government series behind it. That comparison is left out of this page rather than estimated.

What CMHC's financing rules don't distinguish between a condo and a house

Everything above covers where a condo and a house diverge. It's worth being just as precise about where they don't. CMHC's minimum down payment structure — 5% of the purchase price on the first C$500,000, plus 10% on the portion between C$500,000 and the C$1,500,000 insurable price cap — applies identically whether the unit is a condo or a freehold house. The GDS/TDS ceilings of 39%/44% of gross household income apply the same way too; the only difference the ratios themselves create is that a condo fee adds a half-weighted line item a house doesn't have, not a different ceiling to qualify against.

That matters for how you read the comparison this calculator produces. A lower sticker price on a condo doesn't buy easier CMHC qualification rules — the same price bands and the same debt-ratio ceilings govern both paths. What changes the qualifying math between the two options is entirely on the expense side already covered above: the 50%-weighted condo fee eating into GDS/TDS room, the reserve-fund contribution built into that fee, and the separate unit-owner insurance policy a house buyer never has to budget for. Two buyers with identical gross income and an identical purchase price start CMHC's math from the same place; the condo fee is what moves one of them closer to the ceiling.
