The Hidden Costs of Homeownership

By Georges Matar · June 29, 2026 · 6 min read

The mortgage payment is the number the bank decides on, and it is also the only number most buyers budget for. Owning a property costs considerably more than that, and a good share of the bill arrives after closing, when your account is at its lowest.

This article is about the cost of owning. For the cash you need on the day of purchase, read the real cost of a first home instead.

What the notary asks for beyond their own fee

Notary fees have been unregulated since 1991: there is no fixed tariff, only the ethical duty that they be fair and reasonable. Published 2026 estimates run from about $1,500 to $3,500 for a financed purchase, disbursements and taxes included. Ask for a written quote.

But the statement of disbursements also contains items almost nobody anticipates:

Pro rata adjustments. The seller has often already paid municipal and school taxes for the whole year, and sometimes the month’s condo fees. You reimburse them for the portion covering the period after your possession date.
Sales tax on the mortgage insurance premium. If your down payment is under 20 %, the CMHC premium is added to your loan, but the provincial sales tax on it is not: 9 % today, 9.975 % starting in 2027. That one is paid in cash, at the notary.

The full sequence is laid out in the Quebec notary process.

The certificate of location, the document that derails timelines

The seller normally supplies it, and only a land surveyor is qualified to produce one. The Chambre des notaires and the OACIQ both instruct their members to require a certificate less than ten years old, even when nothing appears to have changed on the lot.

The trouble starts when the existing certificate is out of date or no longer reflects the property, after a pool, a shed or an addition. A new one has to be ordered, and a surveyor’s lead time is never immediate. Settle this at the offer stage, not three weeks before signing.

Transfer duties: the bill that arrives once you have forgotten it

The 2026 base regime sets 0.5 % on the first $62,900, 1 % on the portion from $62,900.01 to $315,000, and 1.5 % above $315,000. The thresholds are indexed annually, municipalities may add their own brackets above $500,000, and Montreal has extra latitude.

The real catch is elsewhere: the municipality sends the bill several months after the transaction, and it is payable quickly. Set the money aside on closing day, in a separate account, and leave it there. Estimate it with the welcome tax calculator, and read the welcome tax guide for the exemptions and the tax credit that refunds part of it.

Municipal and school taxes, every year

Municipal. In Montreal, rates vary by building category and by borough, and for 2026 the city council capped the increase in the tax burden under its control at 3.4 %, with each borough then adding its own. In Laval, the 2026 bill combines a base residential rate of $0.4973 per $100 of assessment, an ARTM contribution, a water contribution, and a water service charge of $486 per dwelling. The city allows payment in 2, 6 or 12 instalments, with charges attached to the spread out options.

The takeaway: two properties at the same price, in two different municipalities, do not produce the same tax bill. Check before you buy, not after. How property tax works covers the assessment mechanism.

School. The rate is the same across Quebec: $0.07899 per $100 of adjusted standardized assessment for 2026-2027, after a basic exemption on the first $25,000. It is set by the Ministère de l’Éducation and published in the Gazette officielle du Québec by June 15. On the island of Montreal, the Comité de gestion de la taxe scolaire does the billing.

Home insurance, mandatory in practice

No law requires you to insure your home. Your lender does, and it requires being named on the policy as mortgage creditor. You will have to provide proof of coverage before signing, and keep it in force for the life of the loan.

Two things move the premium far more than square footage: replacement value coverage rather than actual cash value, and the endorsements for sewer backup and water damage. Shop before you make an offer, not the night before closing. An older building, a roof near the end of its life or an oil tank changes an insurer’s answer, and sometimes turns it into a refusal.

Condo fees are rising, and the law explains why

If you are buying a divided co-ownership unit, the rules have changed. The Règlement sur les copropriétés divises has been in force since August 14, 2025.

Every syndicate has three years and one day to produce a maintenance logbook and a first contingency fund study. The logbook inventories the common portions and plans major repairs over 25 years. The study is revised every five years, ten for small co-ownerships of eight units or fewer. Once the study is in, the board has 30 days to adjust contributions, and up to ten years to top up an underfunded reserve.

Translated for a buyer: low fees in a building that has not yet done its study are not good news, they are a deferred invoice. Insist on the building condition attestation, which the syndicate must provide within 15 days of the seller’s request. It states the contingency fund balance, contributions for the last three years, insurance, claims over the last five years and work planned over ten. See also condo fees.

Maintenance, electricity and the other ongoing costs

You will see a rule of thumb quoted for maintenance, a percentage of value to set aside each year. That figure has no official source and depends entirely on the age of the building, its history and what the inspection revealed. The right method is the reverse: start from the inspection report, price the components near the end of their useful life, roof, windows, water heater, weeping tile, and spread each cost over its remaining years. The pre-purchase inspection exists for exactly this.

For electricity, the figures are public. Since April 1, 2026, Hydro-Québec’s Rate D charges 46.154 cents per day in system access fees, 7.065 cents per kilowatt hour up to 40 kWh per day, and 11.142 cents for the rest, after a 3 % increase for domestic rate customers. It is that second tier that matters: a house larger than your apartment crosses into it every winter.

The first-year costs nobody budgets for

The move first. Quebec’s Office de la protection du consommateur recommends comparing two or three companies, checking their record with the Office, and above all insisting on a written contract that sets out costs, included services, dates and the cancellation policy. It also points out that a ten day cooling off period does not always exist.

Then everything that did not exist in a rental: appliances when they are not included, blinds and curtains for a whole house, a mower, a blower, tools, locks to change. And the first full tax bill, which often lands a few months after the transfer duties.

Add these up with the closing costs calculator, then compare the total honestly to your current rent with the rent versus buy calculator. The difference, combined with the equity you build, has to justify the move. If it does not, it is better to know now.
