Pre-construction homes in Ontario tend to concentrate wherever there's still land to open up, and in York Region that increasingly points to East Gwillimbury. In Queensville and the rest of East Gwillimbury's growth towns, a lot of what's for sale hasn't been built yet. You're buying a pre-construction home from a builder's floor plan, in a release the industry calls phase one, and that first release is usually the lowest price you'll ever see for that home. The appeal is simple: more house for your money, in a town on its way up. The catch is that you commit before the home exists, then live through the construction that follows. That trade-off is the whole decision.
What "Phase One" Actually Means
Builders open a new subdivision in stages. Phase one is the first block of homes released for sale, and it's typically priced below the phases that follow, because the builder is selling into an empty site with years of work ahead. As each later phase opens, prices generally step up. You buy from the builder's own sales centre, often months or years before the house, or even the street, is finished.
In East Gwillimbury this is most common in Queensville, the community with the most undeveloped, highway-adjacent land left and the largest projected growth in the township. You'll also find pre-construction homes in Sharon and Holland Landing. If you want to be early somewhere that's genuinely still being built, Queensville is the clearest example.
The Upside: More House for Your Money, Earlier
The phase-one price is the headline reason buyers do this. Getting in at the first release can mean a larger or better-finished home than the same budget buys on the resale market nearby.
The second reason is specific to East Gwillimbury: new-build value here is underwritten by what is being built around it. The Bradford Bypass will add a Highway 400-to-404 freeway link through northern EG. Queensville is the proposed site for the area's new hospital, has two new schools on the way, and already has the HALP Centre open. Buying in phase one means buying ahead of those milestones rather than after they're reflected in prices. None of that is a guarantee, and anyone quoting you a precise future number is guessing, but the direction is well supported.
There's a third reason that gets less attention, and it matters most if this isn't the home you plan to stay in. Buying at phase one can shorten the timeline on your home's appreciation. The price steps between later phases, plus the infrastructure arriving around you, do early work on your equity that a flat resale purchase would leave to time alone. For Buyers treating this home as a stepping stone, that compressed equity gain is what gets you into the second home, or the forever home, years sooner than saving alone would. The same caution applies, growth can stall and nothing here is guaranteed, but it's the honest strategic case for accepting the construction years: you're trading patience now for position later.
The Trade-Offs You're Really Signing Up For
A phase-one home asks for patience. For the first few years you may be living beside active construction: unfinished roads, fenced lots, trucks, and neighbours whose houses are still going up. Some buyers barely notice it; others find the noise and the half-built streetscape wear on them. Be honest with yourself about which one you are before you sign.
Timelines are the other reality. New-home agreements are usually written so the builder can move the closing date, so a multi-year wait is common and you often have limited recourse if it slips. Ontario's Tarion warranty does set a floor here: if a builder misses the firm closing date for reasons within its control, it owes delayed-closing compensation of $150 a day toward living expenses, up to a maximum of $7,500. That helps, but it's capped, and the date can still move legitimately under the contract.
Your deposit is better protected than many buyers assume. Tarion protects a freehold deposit up to $60,000 on homes priced at $600,000 or less, and 10% of the price to a maximum of $100,000 above that; condominium deposits are covered up to $20,000. Since 2026, you need to register your agreement with Tarion within 45 days of signing to secure the maximum coverage, so that step isn't optional. What your specific agreement says about the deposit, and what happens to your money if the project is cancelled or the builder fails, is the first thing to read.
HST and the New First-Time Buyer Rebate
One number that catches resale buyers off guard: a new build is subject to HST, where a resale home isn't. That tax is usually built into the builder's advertised price, but you need to confirm how your agreement handles it. The bigger recent change is the federal First-Time Home Buyers' GST Rebate, which is now law.
By the numbers, the new GST rebate: For first-time buyers, it removes the GST on a new home valued up to $1,000,000, a saving of up to $50,000, then phases out between $1M and $1.5M, with nothing above $1.5M. It applies to agreements of purchase and sale signed on or after March 20, 2025, and received Royal Assent on March 12, 2026. At least one purchaser must be a first-time buyer using the home as their primary residence.
A separate, longstanding GST/HST New Housing Rebate may also apply to other new-build buyers on a smaller scale. Either way, the tax on a new build looks very different depending on whether you qualify as a first-time buyer, so work it out before you commit to a floor plan.
When the Builder Sells Direct, Bring Your Own Read
Most buyers don't realize that many builders won't work with an outside agent at all; they sell entirely through their own sales centres. That doesn't mean you should walk in alone. You can still bring your own representation to check the builder's reputation and track record, read the pre-construction agreement closely (deposit protection, closing and extension clauses, what is and isn't covered), and sanity-check the asking price against real resale comparables in the same community. The sales centre works for the builder. It helps to have someone reading the fine print for you.
Bottom line: A phase-one home in East Gwillimbury can be a real head start: a lower entry price in a town still being built out, ahead of the hospital, schools, and highway work rather than after. But it's a different purchase than a resale home. You're buying time and a tolerance for construction, and the contract details (deposit protection, closing terms, and your tax situation) matter more than the sticker price.
Common Questions
Is buying pre-construction in East Gwillimbury worth it?
The phase-one release is usually the lowest price you'll see for a home, and new-build value in East Gwillimbury is underwritten by what's going up around it: the Bradford Bypass, the confirmed Queensville hospital, and new schools. The trade-off is patience, with years of living beside active construction and closing dates the builder can move.
What are the risks of buying a pre-construction home?
The main ones are living next to active construction for years, closing dates the builder can move, HST on a new build, and deposit protection limits. Ontario's Tarion warranty protects freehold deposits up to $60,000 on homes at or below $600,000, and 10% of the price to a maximum of $100,000 above that. Read the agreement closely before you commit.
Do pre-construction homes in Ontario qualify for the GST rebate?
For first-time buyers, the federal First-Time Home Buyers' GST Rebate removes the GST on a new home valued up to $1,000,000, a saving of up to $50,000, then phases out between $1 million and $1.5 million. It applies to agreements signed on or after March 20, 2025. Pre-construction homes in Ontario carry HST where resale homes don't, so confirm how your agreement handles it.
