Buying New Construction in Waterloo Region: The 2026 Pre-Construction Guide

June 12, 2026 · 7 min read

By William Forbes, Realtor®

New construction is a big part of what I do, and it is the part of the market where good representation matters most, because you are not buying a finished home you can walk through. You are signing a contract for something that does not exist yet. The home is usually fine. It is the agreement that hurts people. So here is the plain-language version of what you are actually getting into when you buy pre-construction in this region, and where I spend my energy protecting buyers.

It is not one closing, it is up to three

The first thing people get wrong is assuming pre-construction works like resale: one offer, one closing, done. It does not. A pre-construction purchase can have up to three separate stages, and understanding them is the whole game.

You sign the agreement and begin paying deposits. Then, on a condo, there is interim occupancy, where you move in after your unit is ready but before the building is legally registered. And finally there is the real closing, where title actually transfers and your mortgage funds. People sign focused only on the purchase price and then get blindsided by everything that happens between those dates.

Occupancy fees, the cost almost nobody warns you about

Let me dwell on the middle stage, because it is the one that surprises people most.

With a pre-construction condo, once your unit is finished you can move in, but the building is not registered yet, so you do not own it. During that window you pay a monthly occupancy fee. It covers the interest on the unpaid balance of the price, an estimate of the property taxes, and the condo fees. Here is the catch that matters: none of it goes toward your mortgage principal. It builds zero equity. People call it phantom rent for a reason, and it is an honest name.

Interim occupancy often runs a few months to a year, but contracts can allow much longer, and in 2026 registration backlogs are stretching some of them out. So when I help a buyer underwrite a pre-construction purchase, I make sure we budget for the real possibility of paying that fee for a while. It is not a deal-killer, but it has to be planned, not discovered.

Your 10-day safety net, and its limits

There is real protection if you sign and then have second thoughts, but only on a condo. When you buy a pre-construction condo directly from the builder, you get a 10-day cooling-off period. You can cancel for any reason within 10 calendar days and get your full deposit back with interest. The clock starts on the later of when you receive the signed agreement or the builder's disclosure statement, and weekends count.

The scope is where people get tripped up, so hear this clearly: that cooling-off period applies to pre-construction condos only. It does not apply to new freehold homes, where that protection is expected to begin in 2027, and it never applies to resale. Do not assume you have a 10-day out on a freehold purchase, because right now you do not.

Check the builder, then trust the protections

In Ontario it is illegal to build or sell a new home without a licence from the HCRA, and you can look any builder up yourself on the Ontario Builder Directory before you sign. I do that on every project. Check the licence, check the record. It takes a minute and it tells you who you are dealing with.

The deposit protections here are genuinely strong, which is one of the quiet upsides of buying new. On a condo, every dollar of your deposit is held in trust by the builder's lawyer, with a Tarion backstop of up to $20,000 per unit on top. On a freehold home, Tarion protects deposits up to between $60,000 and $100,000 depending on the price. Then once you take possession, the Tarion warranty kicks in: one year on workmanship, two years on things like water penetration and the major mechanical systems, and seven years on major structural defects. That warranty is included in the price, and it transfers if you sell.

The 2026 HST rebate changed the math

There was a significant change to the HST rebate this year, and it tilts the numbers toward new construction. On qualifying new homes valued up to a million dollars, the rebate can return the full provincial HST and, with the federal portion, bring combined relief up to $130,000. On a lot of homes in our price range, that materially lowers the net cost. The exact dates and caps matter and the program has a deadline, so check the current details, which I keep updated in my dedicated guide to the Ontario new-home HST rebate.

The nuance is who claims what. Owner-occupiers claim the New Housing Rebate. Investors who rent the unit out claim a different rebate, the rental property rebate, and the mechanics are different, often you pay the HST and then recover it. This is exactly the kind of thing you want an accountant to confirm for your specific situation, but the headline is simple: buying new became more attractive on an after-tax basis.

Watch the development charges. This is the trap.

If there is one closing-cost surprise I want you to avoid, it is development charges. These are municipal fees on new construction, and they can be a large number. The trap is that many builder agreements let those charges increase during construction, so you sign expecting one figure and get a bigger bill at closing.

The single most valuable thing I do on a pre-construction deal is push to negotiate a cap on development charges and levies into the agreement. An uncapped clause is the number one closing-cost shock I see, and it is entirely avoidable with the right wording. All in, budget roughly 5% to 8% of the price for closing costs on a new build, covering land transfer tax, legal, HST adjustments, the Tarion enrolment fee, utility hookups, and those development charges.

New or resale: my honest take

Both are right for different people, and I will not pretend new is always better. New gets you the Tarion warranty, current energy efficiency, the ability to choose finishes, no bidding war against other buyers, and right now that enhanced HST rebate. The trade-offs are just as real: construction delays, those occupancy fees that build no equity, development-charge risk, and the fact that you are buying off a floor plan rather than a finished home you can inspect.

Where I earn my place is being the person at the builder's table who actually works for you. The on-site sales rep is paid by the builder and represents the builder, full stop. I am an independent buyer's representative, and in most cases that costs you nothing, because the builder pays the cooperating brokerage. I read the agreement, flag the uncapped charges, explain the occupancy exposure, and verify the licence. I also work directly with a number of active projects across Waterloo Region, Guelph, and Stratford, so I can tell you what each community is really like on the ground, not just what the rendering promises. And I will connect you with a mortgage partner who knows how to plan financing around a two or three year closing, which is its own skill. If you are considering a pre-construction purchase, talk to me before you sign anything. That is the moment representation is worth the most.

Frequently asked

Do I need a realtor to buy new construction?

The price is the same whether you bring your own agent or not, because the builder sets it. But the on-site sales rep works for the builder. An independent buyer's representative reviews the agreement, flags uncapped development charges, explains occupancy fees, verifies the builder's licence, and negotiates for you, usually at no cost to you because the builder pays the cooperating brokerage.

What is interim occupancy?

On a pre-construction condo, interim occupancy is the period when you can move in after your unit is ready but before the building is legally registered. You live there and pay a monthly occupancy fee, but you do not own the unit yet and you are not paying down a mortgage. That fee builds no equity, which is why people call it phantom rent.

Can I get the HST rebate on a new build in Ontario?

Owner-occupiers claim the GST/HST New Housing Rebate. Under Ontario's 2026 enhancement, eligible new homes valued up to $1 million can see the full HST rebated, up to $130,000, for agreements signed between late May 2025 and the end of 2030. Investors who rent the unit out claim the New Residential Rental Property Rebate instead. The rules are detailed, so confirm your situation with an accountant.

What is the 10-day cooling-off period?

When you buy a pre-construction condo directly from the builder, you get an automatic 10-calendar-day right to cancel for any reason and receive a full deposit refund with interest. The clock starts on the later of receiving the signed agreement or the builder's disclosure statement. Important: this applies to pre-construction condos only. It does not apply to new freehold homes (that protection is expected to begin in 2027) or to resale.

How much deposit do I need for a pre-construction condo?

Typically 15% to 20% of the price, paid in installments on the builder's schedule rather than all at once. A common pattern is 5% on signing followed by staged payments over the following months. Some promotions run lower. Freehold new-build deposits are usually smaller.

Is my deposit safe if the builder goes under?

For a condo, every dollar of your deposit is held in trust by the builder's lawyer under the Condominium Act, with a Tarion backstop of up to $20,000 per unit. For a freehold home, Tarion protects deposits up to between $60,000 and $100,000 depending on the price. It is one of the real protections of buying new in Ontario.

What warranty comes with a new home in Ontario?

The Tarion warranty: one year on workmanship and materials, two years on things like water penetration and the electrical, plumbing, and heating systems, and seven years on major structural defects. It is included in the price and it transfers to the next owner if you sell.

What closing costs should I budget on a new build beyond the price?

Land transfer tax, legal fees, HST adjustments, the Tarion enrolment fee, utility hookups, a condo reserve-fund contribution, and development charges or levies, which can be significant if they are not capped. Plan for roughly 5% to 8% of the price, and always try to negotiate a cap on development charges into the agreement.
