Yes. New construction homes in Quebec usually have extra closing costs compared with resale homes because GST and QST may apply, rebate rules can change the advertised price, and new-build contracts often include deposits, upgrades, occupancy timing, utility hookups and adjustment items that resale buyers do not always face. You should budget beyond the down payment and confirm whether the builder’s price is shown before tax, after tax, or net of rebates.
If you are comparing a new condo in Montreal, a townhouse project in the West Island, or a detached new-build off-island, the safest move is to model the full cash requirement before you sign. Start with our broader closing costs Quebec guide, then use this new-construction checklist to pressure-test the builder’s numbers.
For new construction homes in Quebec, the big difference is sales tax. GST is 5% and QST is 9.975% on most newly built residential property, although eligible owner-occupants may qualify for partial rebates administered in Quebec through Revenu Québec. On top of tax, you still need to account for the notary, land transfer duties, municipal and school tax adjustments, insurance, moving costs, inspection, financing fees, condo contingency costs if applicable, and builder-specific extras such as upgrades or occupancy adjustments.
That does not mean every new-build is a bad deal. It means you cannot compare a $650,000 resale home with a $650,000 new construction home by looking only at the headline price. One price may include tax rebates; the other may not have GST/QST at all. That difference can change your cash planning, mortgage approval and negotiation strategy.
In Greater Montreal, new construction is often marketed differently from resale property. A builder may advertise a base model, then add premiums for a better floor, parking, locker, larger lot, finished basement, appliance package or design centre upgrade. In a resale transaction, those items are usually part of the existing property. In new construction, they can become line items that affect tax, financing and your total out-of-pocket cost.
This is especially important if you are shopping in areas where resale inventory is tight. Buyers looking at homes for sale west of Montreal sometimes compare established communities such as Dorval, Pointe-Claire, Beaconsfield and Baie-D’Urfé with newer projects farther west in Vaudreuil-Dorion, Saint-Lazare or nearby off-island markets. The monthly payment can look attractive, but the closing-cost profile is different.
If you are still deciding between property types, read our Montreal condo vs house guide before you commit. New construction condos, new townhomes and new detached houses each carry different risks.
Here is the practical list you should review before signing a promise to purchase or builder contract:
Some of these apply to resale too. The extra risk with new construction is that the largest item, GST/QST, may be hidden in the way the price is presented.
Usually, yes. New homes and substantially renovated homes are generally taxable. The seller or builder may collect GST and QST, or the contract may show a price that is tax-included or net of eligible rebates. The wording matters.
Revenu Québec states that rebates may apply for owners of new or substantially renovated housing, but the rules depend on occupancy, relationship to the first occupant, fair market value or purchase price, and timing. Canada.ca also notes that in Quebec, Revenu Québec generally administers the GST/HST new housing rebate process. In plain English: do not assume the rebate is automatic just because the sales centre says the price is “after rebate.” Ask for the math in writing.
For many Montreal-area buyers, the key questions are:
If you are buying as an investor, the rebate conversation is different. Rental property rebates have their own eligibility rules and deadlines. Confirm with your accountant or tax professional before relying on a sales-centre estimate.
As a working rule, buyers should budget more conservatively for new construction than for resale. For a resale home in Quebec, many buyers plan for land transfer duties, notary, inspection, adjustments and moving costs. For new construction, you need that resale budget plus tax/rebate analysis and builder-specific extras.
The exact number depends on the contract. A lower-priced new condo with rebates built into the posted price may require less extra cash than a higher-priced home where rebates are unavailable. A detached custom or semi-custom home with upgrades can create a larger gap between “base price” and final cost.
If you are planning your cash, build three columns:
You can cross-check the basic resale items in our closing costs Quebec guide and then add the new construction layer from this article.
“Net of rebate” means the advertised price may already assume that you qualify for a GST/QST rebate and assign that rebate to the builder. This can make the price look simpler, but it can also create confusion.
For example, if the builder says the price is $599,000 net of rebates, you should ask for the gross price, GST, QST, rebate amounts, and final net price. If you do not qualify for the rebate because the home is not your primary residence, because occupancy rules are not met, or because the price exceeds the threshold, you may have to pay more than expected.
This is one of the most common mistakes we see when buyers compare new construction with current Montreal listings. The resale listing price and the new-build advertised price are not always equivalent.
Yes. Buying new does not exempt you from the normal Quebec closing process. You still sign with a notary, register ownership and usually pay land transfer duty. In Montreal, land transfer duties can be a meaningful cost, especially once the purchase price rises into higher brackets.
A new construction buyer should also ask when the welcome tax bill will arrive. It may not be paid at the notary the same way every buyer expects; municipalities typically bill after registration. You should keep cash available rather than spending every dollar on upgrades, furniture or moving.
If you are a first-time buyer, also review our FHSA vs Home Buyers’ Plan Quebec guide. Programs and registered-account withdrawals can help with cash flow, but they do not remove the need to budget for closing.
Yes. New does not mean perfect. A pre-delivery inspection is standard, but it is still worth considering independent professional advice, especially for a house, townhouse or small condo project where deficiencies can be expensive.
Look for grading, drainage, windows, doors, roof details, HVAC, electrical panels, plumbing fixtures, caulking, balcony details, insulation access and finish quality. In Quebec, weather matters. A small exterior grading issue in summer can become a water-management problem after freeze-thaw cycles.
If you are unsure what to look for, use our home inspection checklist Quebec as a starting point. If you are being pressured to waive inspection in a competitive resale situation, compare that with our guide on how much to offer on a house in Montreal, because price and conditions should be negotiated together.
New condo fees can look artificially low at launch. The first budget may be based on estimates, and the building’s true operating costs may become clearer only after the syndicate has lived with real insurance, maintenance, snow removal, utilities, elevator service and reserve-fund obligations.
That does not mean you should avoid new condos. It means you should treat the first-year condo fee as a forecast, not a guarantee. Ask for the projected budget, contingency fund contribution, insurance assumptions, number of units, common-area obligations and any working capital contribution due at closing.
If you are comparing a new condo with an older building, read can condo fees increase after buying in Montreal and our condo vs house Montreal guide.
Upgrades are where many budgets drift. A buyer starts with the base price, then adds flooring, counters, lighting, plumbing fixtures, finished basement space, an EV charger, extra parking, landscaping or appliance packages. Some upgrades are worth it; others are easier to do later.
Before choosing upgrades, ask:
A $20,000 design-centre decision can be reasonable in the right property. It can also become a problem if it leaves you short for welcome tax, inspection follow-up or moving costs.
Some new construction purchases involve assignment sales, where you buy the original buyer’s contract before final closing. Assignment deals can be useful, but they require careful review because deposits, tax treatment, assignment profit, builder consent, occupancy timing and mortgage approval can be more complicated than a straightforward resale.
Occupancy fees can also surprise buyers in certain projects. You may be allowed or required to occupy before final registration, while paying an interim amount that is not the same as your final mortgage payment. Ask exactly when you become responsible for insurance, condo fees, utilities, occupancy charges and property tax adjustments.
If the deal feels complex, slow down. A strong purchase strategy is not just about winning the unit; it is about protecting your closing.
Resale is usually simpler. New construction can be cheaper in repairs at the beginning but more complicated in taxes, contract terms and delivery risk. The better choice depends on your cash position, tolerance for uncertainty, timeline and neighbourhood priorities.
Choose new construction if you value modern layouts, energy efficiency, warranty coverage, lower immediate maintenance and the ability to customize. Choose resale if you want an established street, clearer comparable sales, mature landscaping, known tax bills and fewer construction-delivery variables.
In the West Island, buyers often compare established homes in Pointe-Claire, Dorval, Kirkland and Beaconsfield with newer options west of the island. That comparison is valid, but only if you include the full closing-cost picture.
Before you sign, get these answers in writing:
If any of those answers are vague, you do not yet have the full cost of the home.
Imagine you are comparing two properties: a resale townhouse in the West Island and a new townhouse farther west. Both appear close in price online. The resale home may need painting, inspection follow-up and near-term maintenance, but the closing costs are easier to forecast. The new townhouse may have a cleaner layout and warranty coverage, but the advertised price may be net of rebates, upgrades may be extra, and delivery timing may affect your rent or sale timeline.
Neither option is automatically better. The correct answer depends on your full cash requirement and your next move. If you are selling a home to buy, read how to sell your home in Montreal and coordinate dates carefully. If you are relocating from Ontario, our moving to Montreal from Ontario guide explains several Quebec-specific differences that can affect your plan.
New construction homes in Quebec can be excellent purchases, but they require sharper closing-cost analysis than a typical resale. Your biggest question is not just “Can I afford the price?” It is “Can I afford the real price after GST, QST, rebates, notary, welcome tax, adjustments, upgrades, inspections and timing risk?”
