New Construction vs Resale in Cities and Communities in Eastern Ontario

Choosing between a new construction home and a resale property in Eastern Ontario comes down to five factors: total cost (including taxes and closing extras), timeline flexibility, your tolerance for uncertainty, the features you need on day one, and the specific sub-market where you're buying. Neither option is universally better. The right answer depends on which of those five factors matters most to you.

Eastern Ontario spans a wide range of markets, from Ottawa and Orléans in the north to the St. Lawrence River towns of Brockville, Prescott, Augusta, and the Thousand Islands corridor along Highway 416. Each community behaves differently, and the new-construction landscape in suburban Ottawa looks nothing like what you'll find in a smaller river town. This guide walks through both paths so you can match the right choice to your situation.

How Ottawa's New Construction Pipeline Differs from the Resale Market

Ottawa's new construction pipeline dwarfs what you'll find in the river towns, and that gap shapes your options. The Ottawa region had 17,212 housing units under construction as of May 2026, according to CMHC data cited by the Ottawa Real Estate Board, with the large majority of those units being apartment-style, reflecting a pipeline that has shifted heavily toward multi-unit and rental construction in recent years.

On the resale side, the Ottawa market is balanced but more buyer-friendly than it has been in several years. In July 2026, the Ottawa Real Estate Board reported 4,678 active residential listings, up 9.3% year over year and high relative to recent historical trends, alongside 3.5 months of inventory. The composite MLS® Home Price Index benchmark stood at $634,000, down a modest 0.5% year over year. The market is clearly segmented within that headline figure: the single-family benchmark held at $725,000 (up 0.6% year over year, per the OREB July 2026 release), while townhouses benchmarked at $542,500 (down 5.1%) and apartment-style condos at $385,500 (down 5.2%).

For buyers comparing the two paths, that segmentation is practically important. If you're considering a new townhouse or a new condo in Ottawa, you're entering a segment where resale pricing has softened meaningfully, which affects how a new build's sticker price holds up by comparison.

Outside Ottawa, communities such as Brockville, Prescott, Leeds, and the Thousand Islands corridor have smaller and more variable markets. Aggregated MLS listing data for the Brockville-Prescott corridor through mid-2026 shows resale single-family homes broadly ranging from the mid-$400,000s to the low $700,000s, depending on proximity to the St. Lawrence, lot size, and whether the property is in-town or rural. New construction activity in these communities is limited to smaller infill projects, executive subdivisions, or custom builds on rural lots, so resale inventory gives buyers more choice and more immediate comparables.

What "New Construction" Actually Costs in Eastern Ontario

New construction vs. resale in Eastern Ontario is not a straightforward sticker-price comparison. Several costs are specific to new builds and can shift the true cost of entry by a meaningful amount.

HST on new homes. Resale homes are generally exempt from HST. New construction homes are subject to the full 13% HST, though buyers can recover a significant portion through federal and provincial rebate programs. Under the Ontario government's expanded HST rebate announced March 25, 2026 (in effect for agreements of purchase and sale entered into between April 1, 2026 and March 31, 2027), eligible buyers of new homes can receive a combined federal-provincial rebate of up to $130,000. The rebate structure, per CRA Notice 346, is as follows:

That last tier matters for the Thousand Islands corridor, where waterfront properties frequently exceed $1 million. If you're buying a new build near the St. Lawrence with a purchase price in the $1 million to $1.5 million range, you still receive the full $130,000 rebate, provided the home is your primary residence and the agreement was signed within the eligible window. Above $1.5 million, the rebate begins to decrease; above $1.85 million, it reverts to the existing provincial baseline of approximately $24,000. For above-average-priced new builds, particularly custom waterfront homes, running a precise HST and rebate calculation with your lawyer and accountant before signing is essential. We've covered the mechanics of this program in more detail in our guide to the Ontario HST rebate on new homes.

Development charges in Ottawa. Municipalities pass infrastructure costs onto new-home buyers through development charges. In Ottawa, those fees previously ran as high as $62,568 for a single-family home outside the Greenbelt. Ottawa City Council approved a 54% reduction in residential development charges on July 15, 2026, retroactive to January 1, 2026 and continuing through March 30, 2029, under a federal-provincial infrastructure funding program that was confirmed in August 2026. The before-and-after figures are:

Buyers should confirm the applicable development charge with their builder for any specific project, as the reduction is implemented through a grant mechanism tied to the funding agreement and occupancy conditions apply.

Tarion warranty enrolment fees. New homes in Ontario are covered by the statutory warranty administered by Tarion: one year on workmanship and materials, two years on the building envelope and major systems (electrical, plumbing, heating), and seven years on major structural defects. Builders pass the Tarion enrolment fee on to buyers at closing. It is a relatively modest line item, but it appears on the statement of adjustments and should be budgeted for. Full warranty details are available at tarion.com.

Construction cost context. As of 2026, production new-build homes in the Ottawa area, builder-constructed on pre-planned lots with standardized designs, range from approximately $160 to $230 per square foot for the base structure, according to Altus Group's 2026 Canadian Cost Guide. Custom-built homes in the Ottawa region are significantly more expensive, ranging broadly from $500 to $1,000 per square foot depending on design, finishes, and complexity. Tariff-related materials price pressures through 2025 have added further cost uncertainty for builders operating in both segments. Neither of these dynamics applies to resale, where pricing is determined by what comparable homes sold for in the open market.

New Construction vs. Resale: The Core Trade-Offs

The decision between new construction and resale in Eastern Ontario comes down to a set of practical trade-offs. The table below maps the key dimensions side by side.

A Note on Negotiating Room in the Current Ottawa Market

As of July 2026, the Ottawa Real Estate Board reported a sales-to-new-listings ratio of 52.4% and homes selling at an average of 97.8% of list price, figures that reflect a buyer-friendly balance. That room to negotiate is most pronounced in the townhouse and condo segments, where softness has been sharpest. Builders, by contrast, typically structure their discounting through upgrade packages, deposit flexibility, and rate buydowns rather than headline price reductions. Understanding the dollar value of a builder's incentive package, not just its marketing description, is important before treating it as equivalent to a price cut on a resale offer.

A Note on Inspection Conditions

In the current Eastern Ontario market, most resale offers can include an inspection condition. The period of routinely waiving inspections to compete is less common than it was at the height of 2021–2022. For pre-construction new builds, inspections don't apply in the same way, though buyers should arrange their own independent walkthrough at the pre-delivery inspection stage and understand what Tarion covers if deficiencies arise. Our guide to offer conditions in Ontario covers how inspection and financing conditions typically work in a resale offer.

What This Means for Buyers in Brockville, Prescott, the Thousand Islands, and Highway 416

In Brockville, Prescott, Augusta, and the Thousand Islands corridor, resale is the practical default. New construction supply is limited and mostly confined to custom builds or small infill projects. Buyers with very specific location requirements, particularly near the St. Lawrence waterfront, will find the resale market gives them far more to work with.

Resale in these communities covers a wide range: entry-level in-town bungalows and two-storey homes from the mid-$400,000s; mid-range two-storey and newer-build properties broadly in the $500,000s to $650,000s; and above-average waterfront or acreage properties that can extend well into the $700,000s and beyond depending on river frontage, lot size, and property condition. Waterfront homes carry a meaningful premium and bring additional considerations: insurance, well and septic systems, road access, and in some cases a narrower lender search than urban properties. Our Brockville waterfront living guide goes into more detail on that segment specifically.

Rural and acreage properties in Leeds and the broader Thousand Islands region may require more specific appraisal support and careful review of access easements, road maintenance agreements, and seasonal-use factors. Buyers relocating to this corridor, for retirement, remote work, or a lifestyle change, should budget time for due diligence that goes beyond a standard urban purchase.

For buyers who do want a new build in this corridor, supply constraints mean you are likely looking at a custom build on purchased land, which introduces a different set of financing structures (construction mortgages drawn in stages rather than a single close) and a wider range of cost uncertainty than a builder's fixed-price contract in an established Ottawa subdivision.

Financing Considerations That Differ Between New and Resale

New construction and resale purchases involve meaningfully different financing timelines, rate-hold strategies, and property-specific lender requirements, and those differences can affect both your total cost and your risk exposure.

New construction financing carries one risk resale doesn't: you sign today but don't close for one to three years, and your rate hold won't bridge that gap. The Bank of Canada held its policy rate at 2.25% at the July 15, 2026 rate decision, which has helped keep fixed and variable rates steadier than during the 2022–2023 tightening cycle. Buyers qualifying under OSFI's mortgage stress test are still stress-tested at their contract rate plus two percentage points, a number worth confirming with your mortgage professional before making any offer on either type of home.

For new construction, the extended timeline creates specific rate-risk exposure. You sign a purchase agreement today at today's prices, but you don't close for twelve to thirty-six months. Most rate holds expire well before then, meaning you'll need to re-qualify under whatever conditions prevail at closing. In a stable or declining-rate environment, that risk is manageable. In a rising-rate environment, it is not. Understand your builder's deposit structure and how your financing will need to bridge the gap between signing and closing.

Waterfront and rural properties in communities like Prescott, Augusta, and the Thousand Islands also come with property-specific financing considerations (documentation for well and septic systems, appraisal requirements that can affect lender appetite, and in some cases a narrower set of willing lenders) that don't apply to urban resale or new-build purchases in established Ottawa subdivisions.

Speaking with a mortgage professional early is a practical way to stress-test different purchase price scenarios before you start viewing properties; our buyer services overview outlines what that conversation typically covers.

Making the Right Call: A Decision Checklist

Before choosing between new construction and resale in Eastern Ontario, work through these questions:

1. Timeline: Can you accommodate a twelve to thirty-six month wait alongside your current rate-hold situation and living arrangements? If not, resale is the more practical path.
2. Location priority: Do you need a specific school zone, established neighbourhood, or proximity to the St. Lawrence? Resale gives you precision; new builds give you finish flexibility but less location certainty.
3. HST rebate eligibility: If you're purchasing a new home with an agreement signed between April 1, 2026 and March 31, 2027, confirm your eligibility for the expanded rebate. At or below $1 million, that rebate can be up to $130,000. Between $1 million and $1.5 million, the $130,000 maximum is maintained. Above $1.5 million, it decreases, and above $1.85 million, it reverts to the existing provincial baseline of approximately $24,000. Run the numbers carefully if you're buying in that range.
4. Ottawa development charges: For new builds in Ottawa, confirm the applicable development charge with your builder. Following City Council's July 2026 approval of the 54% reduction, the charge on a typical suburban single-family home outside the Greenbelt has fallen from approximately $62,568 to approximately $28,781, a meaningful improvement in the cost comparison with resale.
5. Total closing costs: For new construction, model HST (net of rebate), development charges, Tarion fees, utility connections, and any finishes not included in the builder's base price. For resale, account for land transfer tax, legal fees, and inspection results; our closing costs guide breaks both down in full.
6. Inspection comfort: Are you comfortable proceeding without a traditional home inspection (pre-construction new build) or is a thorough inspection a non-negotiable step? Most resale offers in today's Eastern Ontario market can include an inspection condition.

Choosing Between New Construction and Resale in Eastern Ontario

Whether you're comparing a new townhouse in Orléans to a resale in Barrhaven, or weighing a custom build outside Brockville against an established home in Prescott, the new construction vs. resale decision in Eastern Ontario ultimately rests on the same framework: total cost once all closing items are factored in, timeline you can actually live with, and the neighbourhood context that fits your life. The current market, with more inventory, a meaningful development charge reduction in Ottawa, and the expanded HST rebate still in effect for new builds, gives buyers on both sides of this decision more to work with than has been typical in recent years.

FAQ

• Does a new construction home in Eastern Ontario always cost more than a comparable resale? Not always, but once you account for HST, development charges, Tarion fees, and finish upgrades, the true cost of a new build often exceeds the sticker price significantly. The expanded HST rebate available for eligible purchases between April 1, 2026 and March 31, 2027 (up to $130,000 on qualifying homes) and Ottawa's approved 54% development charge reduction both improve the new construction cost equation meaningfully. Run a complete comparison of all closing costs on both sides before concluding which option is less expensive.
• How long does the Tarion warranty protect buyers of new homes in Ontario? Ontario's statutory warranty, administered by Tarion, provides three tiers of coverage: one year on workmanship and materials defects, two years on the building envelope, electrical, plumbing, and heating systems, and seven years on major structural defects. Coverage begins on the date you take possession of the home. For more information on what the warranty covers and how to make a claim, Tarion's homeowner resources are available at tarion.com.
• Are new homes available in Brockville, Prescott, and the Thousand Islands, or only in Ottawa? New construction exists along the Highway 416 corridor and in the river towns, but supply is much more limited than in Ottawa's suburbs. Most new builds in these communities are infill projects, executive subdivisions on the outskirts of town, or custom builds on rural or waterfront lots. Buyers with specific location requirements, particularly near the St. Lawrence, will find the resale market gives them considerably more to work with. If you are open to a custom build, be prepared for construction mortgage financing rather than a standard purchase mortgage.
• Can I include a home inspection condition when buying a resale home in Eastern Ontario's current market? In the current market, which is balanced across most of Eastern Ontario with more inventory than in recent years, most resale offers can include an inspection condition. In Ottawa's suburban single-family segment, where absorption has been firmer, some well-priced properties may attract competition, but the period of routinely waiving inspection conditions is less common than it was during the peak of 2021 to 2022. Budget for a professional inspection: for older in-town properties in communities like Prescott or Brockville, an inspection can surface items like older mechanical systems, updated wiring, or septic considerations that meaningfully affect your offer.
• What is the Ottawa development charge for a new home after the 2026 reduction? Following Ottawa City Council's approval of a 54% residential development charge reduction on July 15, 2026, retroactive to January 1, 2026 and continuing through March 30, 2029, the development charge on a single-family home outside the Greenbelt has fallen from approximately $62,568 to approximately $28,781. Inside the Greenbelt, the equivalent charge drops from approximately $55,982 to approximately $25,752. Buyers should confirm the exact applicable rate for their specific project with their builder, as the reduction is implemented through a grant mechanism and occupancy conditions apply.
• Is it a good time to buy in Eastern Ontario's resale market? The Ottawa Real Estate Board described July 2026 as a steady market with more inventory and greater buyer choice than has been typical in recent years. Active listings stand at 4,678, up 9.3% year over year, with 3.5 months of inventory overall, single-family at 3.2 months, and the condo apartment segment softer at 5.4 months. For buyers working through the purchase process for the first time, our first-time buyer resources cover the process from qualification to closing. Conditions vary significantly by community, property type, and price tier, so the right answer for your household depends on your specific target area and budget more than on any single headline number.
