Kanata REAL ESTATE
Blackstone Kanata South New Homes for Sale
Blackstone is a master-planned Kanata South community built since 2012 by Cardel Homes (north of Cope Drive) and Mattamy Homes (south of Cope Drive), notable for a housing mix that’s a genuine departure from most Kanata builder communities — alongside standard townhomes and two-storey singles, Blackstone offers bungalows and multigenerational floor plans designed for extended families living under one roof.

What Is Blackstone Like?
Where most new Kanata communities lean almost entirely on two-storey singles and townhomes for younger families, Blackstone’s inclusion of bungalow and multigenerational product sets it apart. Multigenerational designs typically include a separate living suite with its own entrance, kitchenette, and bathroom — built for aging parents, adult children, or extended family sharing a home without sacrificing privacy. That’s a real answer to a housing need that’s becoming more common in Ottawa as extended families weigh the cost of a second household against staying together.
Mattamy’s phases have sold out, and Cardel is now the only builder still releasing homes here, so lot availability shifts as sections sell out and new ones release. The Home Construction Regulatory Authority (HCRA) is a useful resource for confirming a builder’s licensing status before signing a purchase agreement.

Should You Buy Pre-Construction or Resale in Blackstone?
A pre-construction purchase through Cardel means selecting your lot and floor plan directly, a structured deposit schedule, and a Tarion-backed new home warranty once you close — Ontario’s new home warranty program covers defects in workmanship and materials for a defined period, worth reviewing in detail before you sign, especially for a multigenerational unit where the secondary suite’s systems (separate kitchenette, bathroom) should be inspected with the same rigour as the main home.
A resale purchase — buying from an early Blackstone owner — moves faster and lets you see the finished product, including how a multigenerational layout actually functions in practice, before committing.

Who Is Blackstone Best For?
Blackstone is a strong fit for extended families actively planning to share a home, downsizing buyers drawn to the bungalow product who want single-level living without leaving Kanata, and move-up buyers who want new construction in Kanata South specifically, closer to Kanata Centrum and the established southern communities than the newer Kanata North builder sites.

What Schools and Amenities Are Near Blackstone?
Blackstone falls within the Ottawa-Carleton District School Board and Ottawa Catholic School Board catchments serving Kanata South — confirm exact assignments directly with the boards as the community continues to build out. Its Kanata South location puts it within reasonable reach of Eagleson Road and Terry Fox Drive for access to Highway 417, and OC Transpo service extends into the area as development progresses.
Blackstone sits on the Kanata and Stittsville border, reached from Terry Fox Drive and from Robert Grant Drive and Abbott Street, with Cope Drive running through the middle. Parks include Rouncey Park, Rubicon Park, Haliburton Heights Park, Bob Mills Park and Blackstone Park, with a connection to the Trans Canada Trail. Nearby public schools include Shingwakons Public School, A. Lorne Cassidy Elementary School and Stittsville Secondary School. Catholic options include St. Bernadette School and Sacred Heart High School. Recent listings have included homes on Cope Drive, Nordmann Firr Court, Feathertop Lane and Abbott Street East. Confirm the designated school for a specific address with the board.
What Should You Know Before Buying a Newer Home in Blackstone?
Because building in Blackstone started in 2012, much of the resale stock is still young enough to carry part of the original builder warranty. That changes how you should shop here compared with an older Kanata neighbourhood.
Ontario new homes are covered by a Tarion warranty in three stages: one year for workmanship and materials, two years for systems like plumbing, electrical, heating and water penetration, and seven years for major structural defects. The coverage runs from the first owner’s possession date and transfers automatically to later owners. Before you firm up on a Blackstone resale, ask the seller for the possession date and whether any warranty claims are open, so you know exactly what protection is left.
Builder matters too. Cardel built north of Cope Drive and Mattamy built south of it, and the two use different floor plans, specifications and finish levels. The fairest price comparison for a Cardel home is another Cardel home, and the same goes for Mattamy. When I pull comparable sales for a Blackstone home, I sort them by builder and model first.
Blackstone is also known for multigenerational floor plans. If a listing advertises a separate suite, a second kitchen or rental income, ask whether that space was built and permitted as a secondary dwelling unit. An unpermitted suite can create problems with insurance, financing and resale, and the City of Ottawa’s permit records will show what was approved.
If you’re buying new from Cardel instead of resale, confirm the builder’s licence on the Home Construction Regulatory Authority register before you sign, and have a real estate lawyer review the agreement. New-home agreements often add costs on closing, such as utility connection fees and Tarion enrolment, that aren’t in the headline price.
Finally, Blackstone sits right on the Kanata and Stittsville border, and daily life tends to lean toward Stittsville. The Cardel Recreation Complex, Stittsville Main Street and the Trans Canada Trail are all close by. Buyers who expect to be walking to Kanata Centrum are usually surprised by the drive, so it’s worth doing your commute at rush hour before you commit.
What Do Homes for Sale in Blackstone Cost?
Market snapshot, October 2026: MLS® area 9010 (Emerald Meadows/Trailwest), the resale area Blackstone falls within, had 110 active for-sale listings on the MLS® System when this page was last updated. Detached homes (32 listings) were asking between $729,900 and $1,215,000, with a median asking price of about $865,000. Townhomes (62 listings) were asking between $315,000 and $689,900, with a median of about $599,900. These are asking prices from the live listing feed, not sold prices. For what homes have actually sold for on a specific street, I pull recent sold comparables directly.
New-build pricing in Blackstone is set by Cardel directly, though the community’s bungalow and multigenerational product tends to hold distinct value from standard townhomes and singles — worth understanding if you’re comparing a resale purchase here to new construction elsewhere in Kanata South. The Ottawa Real Estate Board tracks broader Kanata South resale trends, useful context for how comparable new communities have performed once their initial construction phase sells through.
How Can Jason Help You Buy in Blackstone?
I represent buyers through new-build purchases the same way I would a resale — reviewing the purchase agreement, understanding what’s negotiable with the builder, and walking the pre-delivery inspection with the same eye a Tarion inspector would use, drawing on my background in construction and electrical trades. For a multigenerational unit specifically, that means checking the secondary suite’s electrical, plumbing, and HVAC connections are properly separated and code-compliant, not just cosmetically distinct.
If you’re an extended family coordinating a sale of one or more existing homes to fund a Blackstone purchase, that’s exactly the kind of multi-party timing I help manage — see buying and selling at the same time for how that process works. For the broader new-construction landscape across Kanata, see my new construction Ottawa guide, and CMHC publishes current guidance on financing for multigenerational and new-build purchases, including Ontario’s land transfer tax treatment for multigenerational homes, which can differ from a standard single-family purchase.

Frequently Asked Questions About Blackstone
Blackstone, a Cardel Homes and Mattamy Homes community in Kanata South, is known for offering bungalows and multigenerational floor plans alongside standard townhomes and singles — a housing mix that’s uncommon among Kanata’s newer builder communities.
A multigenerational floor plan typically includes a separate living suite within the home, with its own entrance, kitchenette, and bathroom, designed for extended families to share a property while maintaining privacy.
Pre-construction gives you lot and floor-plan selection plus a Tarion-backed new home warranty, but a longer closing timeline; a resale purchase from an early owner moves faster and lets you evaluate the finished home, including how a multigenerational layout functions, before committing.

Contact me directly for current Blackstone availability, or to discuss coordinating the sale of an existing home against a Blackstone purchase — see buying and selling at the same time.
Cardel Homes built north of Cope Drive and Mattamy Homes built south of it, starting in 2012. Mattamy’s phases have sold out, and Cardel is now the builder still releasing new homes.
Tarion coverage runs in three stages from the first owner’s possession date: one year for workmanship and materials, two years for systems like plumbing, electrical and heating, and seven years for major structural defects. It transfers automatically to later owners, so a newer Blackstone resale may still be covered.
Some multigenerational homes here include separate living space, but not every suite was built and permitted as a secondary dwelling unit. Ask the seller for permit records and confirm with the City of Ottawa, since an unpermitted suite can affect insurance, financing and resale.
