New vs Resale Condo in the GTA: Which Should You Buy?

Price and Price-per-Square-Foot: Sticker vs True Cost

Most buyers compare price-per-square-foot first, but ‘price’ doesn’t mean the same thing for new and resale. According to TRREB (Q4 2025), the average GTA resale condo sold for about $652,945, down roughly 5.1% year-over-year, with the City of Toronto averaging about $690,607. With resale, that figure is essentially your full cost—visible and verifiable.

A preconstruction sticker price often excludes what gets stacked on later: the builder’s development levies (development charges, education levies, park fees), the Tarion enrolment fee, legal review costs, and HST that settles at closing. A precon unit with a similar headline price can end up costing several thousand dollars more all-in.

• Resale: transparent pricing you can verify against comparable sales; negotiating room moves with the market
• Precon: ‘invisible’ closing costs beyond the sticker—before signing, have your agent and lawyer get a cap on levies written into the agreement

There is also a timing dimension to price. With resale, you lock today’s price for an asset you can value today against real comparable sales. With preconstruction, you are buying tomorrow’s home at today’s price, and your bet is on where the market sits 3–5 years out when the building closes. In a softening market—and according to TRREB (Q4 2025), GTA condo prices fell about 5.1% year-over-year—that bet cuts both ways: a precon contract signed at a peak can close into a lower market, while a well-timed resale purchase captures today’s negotiating leverage immediately. Neither is automatically the ‘better deal’; the right answer depends on your read of the market and how much price certainty you want.

Deposit Structure and Cash Flow: Instalments vs Lump Sum

This is the biggest cash-flow difference between the two paths. Resale typically requires your full down payment in one lump sum at closing (owner-occupied minimums start at 5%, tiered by price, plus land transfer tax).

Preconstruction instead lets you pay the deposit in instalments. A common GTA structure is 15%–20% of the purchase price spread out: roughly $5,000 on signing, the balance of 5% within 30 days, another 5% at 180 days, and 5% at 360 days, with some projects taking a final 5% at occupancy (source: GTA-Homes deposit-structure guide). For buyers with limited cash but steady income, instalments can actually be friendlier—you have time to save.

My advice: don’t rush in just because the deposit is ‘low’ up front. Precon often runs 3–5 years from signing to closing, and your deposit sits locked in trust earning nothing—factor in that opportunity cost.

Interim Occupancy and HST: Two Precon-Only Pitfalls

The interim occupancy fee (often called ‘phantom rent’) catches many precon buyers off guard. Once the building is finished but the condominium declaration isn’t yet registered, you can move in—but you’re not the legal owner yet. During this window you pay the builder a monthly fee covering interest on the unpaid balance, estimated municipal taxes, and maintenance. According to multiple GTA real-estate sources (2024), this commonly runs $2,500–$6,000 per month, and it does not go toward your purchase price or your mortgage.

HST is the other big one. According to the Canada Revenue Agency (CRA), new homes (including new condos) are subject to HST; owner-occupiers can apply for the New Housing Rebate, with the Ontario portion capped at roughly $24,000. Note: investors buying to rent generally pay the full HST first, then recover it via the New Residential Rental Property Rebate.

• The interim occupancy period can last several months—budget for it
• HST rebate eligibility and amount differ for owner-occupied vs rental; confirm with an accountant or lawyer before signing

Tarion Warranty and Risk: A New-Home Safety Net vs Resale Certainty

One of the biggest hidden values of precon and new builds is the Tarion Ontario new-home warranty. According to Tarion, coverage has three layers: 1 year on workmanship, materials, and Ontario Building Code violations; 2 years on water penetration, electrical, plumbing, heating, and the building envelope; and 7 years on major structural defects. Before closing there is also deposit protection: if a condo unit’s deposit is lost because the trust fails, Tarion backstops up to $20,000 plus limited interest; if a builder delays delivery without proper notice, compensation runs up to $100 a day to a maximum of $5,000.

Also according to Tarion, starting April 1, 2026, new-home buyers should register their purchase agreement with Tarion within 45 days of signing to activate deposit protection—a new rule your lawyer should track.

Resale has no Tarion, but it offers its own certainty: you can get a home inspection, review the actual maintenance-fee and reserve-fund records, and confirm whether any special assessments exist. New construction bets on ‘delivered on time and to spec’; resale bets on ‘building age and upkeep’—different risks, not strictly more or less.

It is worth being clear-eyed about the precon risks the warranty does not erase. Delivery dates routinely slip, sometimes by years, and a Tarion delayed-occupancy payment of up to $100 a day to a $5,000 maximum rarely covers the full cost of extended renting or a second move. Projects can also be cancelled outright, returning your deposit but leaving you to re-enter a market that may have moved against you. And the warranty covers defects, not your satisfaction with the final product—finishes, sightlines, and noise are only fully knowable once the building exists. With resale, by contrast, the building, the neighbours, and the management track record are all in front of you on day one. I am not telling you to avoid precon; I am telling you to price these risks honestly instead of assuming the warranty makes them disappear.

On maintenance fees, new buildings often start with low monthly fees (developers keep early budgets lean to sell), but increases a year or two in—as real operating costs and reserve-fund requirements kick in—are common. Resale fees are more ‘honest’: the bills and historical increases are right there to review.

Customization is a precon-only advantage: you choose the floor plan, level, and exposure, and some projects let you select flooring, cabinetry, or upgrade packages. Resale is what-you-see-is-what-you-get; changes mean renovating yourself.

1. Want immediate possession, transparent pricing, and the ability to inspect—lean resale
2. Prefer instalment cash flow, want brand-new finishes and warranty, and aren’t in a rush to move—consider preconstruction
3. Buying to rent—build the HST carrying cost, vacancy during interim occupancy, and delay risk into your return model

Whichever path you choose, set your budget and timeline first, then look at listings. It’s the single piece of advice I give clients most often as a broker.

Is preconstruction always more expensive than resale?

Not necessarily. A precon sticker price can be close to, or even below, comparable resale—but you add 'invisible' costs like development levies, the Tarion fee, HST, and interim occupancy fees. Once those are included, the all-in cost is often higher. Before signing, have your agent and lawyer prepare a full cost comparison and push to get a cap on levies written into the agreement.

What is an interim occupancy fee, and can I avoid it?

The interim occupancy fee (often 'phantom rent') is the monthly amount you pay the builder once the building is finished but the declaration isn't yet registered—covering interest on the unpaid balance, estimated municipal taxes, and maintenance. According to GTA real-estate sources (2024), it commonly runs $2,500–$6,000 per month. You can't fully avoid it, but choosing a unit that registers sooner can shorten the window. Budget for it regardless.

Is my deposit safe when I buy preconstruction?

It's relatively safe. Under section 81 of Ontario's Condominium Act, a new-condo deposit must be held in trust by the builder's lawyer—your first line of protection, covering the full amount. In addition, according to Tarion, if the trust fails there's a backstop of up to $20,000 per unit plus limited interest. Starting April 1, 2026, buyers should register the agreement with Tarion within 45 days of signing to activate that protection.

Resale condos have no Tarion warranty—are they riskier?

It's a different kind of risk, not simply riskier. Resale has no new-home warranty, but you can inspect the unit, review maintenance-fee history, check the reserve fund, and confirm whether special assessments exist—more certainty up front. New construction bets on on-time, on-spec delivery; resale bets on building age and upkeep. The key is using the status certificate and a professional inspection to fully understand the resale risk.

For a first-time buyer, which do you recommend?

It depends on your cash flow and timeline. If you have limited cash but steady income and aren't in a rush, precon's instalment deposit gives you time to save. If you want transparent pricing, the ability to inspect, and immediate possession, resale is steadier. Set your budget and timeline before looking at listings—that matters more than agonizing over 'new' versus 'cheap.'
