It is the largest residential neighbourhood in this area, and the 404 access via Mulock Drive allows most residents to reach the highway in under two minutes.

The neighbourhood comprises four distinct sub-communities, each with unique characteristics. Stonehaven, developed in the 1990s, features hilly streets named after racehorses such as Secretariat, Damascus, and Northern Prospect, with 3,000 to 3,500-square-foot homes in Tudor, Colonial, Georgian, and Victorian Revival styles. Cast-iron lamps line the streets. Wyndham Estates, slightly older and more modest, consists of 1980s and 1990s brick homes. Copper Hills, the newest section, was built from 2007 onward and offers French Provincial luxury homes on 40 to 50-foot lots, triple-car garages, 10-foot ceilings, and some of Newmarket’s most expensive detached properties. Kingdale, an exclusive enclave in the northeast corner, features custom-built estate homes on lots up to two acres, circular driveways, and prices that often exceed $2 million.

Let's pull this apart.

The detached segment is the largest in Stonehaven-Wyndham and currently reflects a buyer’s market. With 17 sales and 61 new listings, the sales-to-new-listings ratio is 28%, indicating that approximately three out of four new detached listings did not sell in Q4. Homes sold at 97% of list price and averaged 36 days on the market, resulting in about $47,000 of negotiating room on a $1,577,000 average sale price. Detached buyers have significant inventory and negotiation leverage.
The semi-detached market presents a contrasting scenario. Six sales and five new listings resulted in a 120% absorption rate, meaning properties sold faster than new inventory came to market. With an average price of $879,000 and 32 days on market, this is the most competitive segment in Stonehaven-Wyndham. Buyers in the $850,000 to $900,000 range should be prepared for limited availability.

The condo townhouse segment, with an average price of $834,000 and an 80% sales-to-new-listings ratio, falls between the detached and semi-detached markets. Four sales and five new listings indicate steady demand. The 98% sale-to-list ratio, the highest in the neighbourhood, indicates that well-priced units are selling near the asking price. This segment offers an accessible entry point for buyers seeking the area’s schools and amenities without the higher prices of detached homes.
The median price exceeding the neighbourhood-level average ($1,343,500 vs. $1,311,674) indicates that semi-detached and condo townhouse sales have lowered the average, while detached home prices remain higher. This reflects the presence of distinct markets within the same neighbourhood.

What Kind of Homes Does Stonehaven-Wyndham Have?

Stonehaven-Wyndham has four distinct housing eras, and they don't look anything alike.

Wyndham Estates is the oldest section, built through the 1980s and into the early 1990s. Brick two-storey detached homes, Wyndham Estates, the oldest section, were developed during the 1980s and early 1990s. It features two-storey brick detached homes and some semi-detached homes with traditional layouts and mature tree canopies. These homes are more modest compared to the neighbourhood’s overall standards and help bring the average price closer to the Newmarket median. Homes span 3,000 to 3,500 square feet in Tudor, Colonial, Georgian, and Victorian Revival styles. Many of the streets are named after thoroughbred racehorses — Secretariat, Damascus, Northern Prospect, Exceller, Foxcroft, Highland Blade. Centre-hall plans with expansive driveways and double garages are the standard. This is the section that most people picture when they think of Stonehaven-Wyndham.

Copper Hills, the newest section, was developed in phases beginning around 2007 by Redwood Properties and Preston Homes. It features French Provincial Manor-style homes on 40 to 50-foot lots with triple-car garages, 10-foot ceilings on both main and second floors, oak staircases, gourmet kitchens with custom cabinetry, and elevator options in select models. These are the most expensive detached homes in Newmarket, offering the highest build quality and finishes, though the lots are not the largest in the neighbourhood.

Kingdale, located in the northeast corner, is an estate enclave featuring custom-built homes on lots up to two acres, circular driveways, and professionally landscaped grounds with mature trees. Prices regularly exceed $2 million, making this the location of Newmarket’s most expensive residential real estate.

What Schools are in Stonehaven-Wyndham?

The school catchment is the best in Newmarket, and it's one of the primary reasons families pay the premium to be here.

The headline is Newmarket High School, which scores 8.5 out of 10 on the Fraser Institute's 2025 Report Card and ranks 42nd out of 747 secondary schools in Ontario. That's a top-6% ranking in the province and the best public secondary in Newmarket by a meaningful margin. The school has been trending upward, improving from an average ranking of 51st over the past five years to 42nd in the latest report.

Catchment details are important in this neighbourhood. Stonehaven-Wyndham is large enough that different streets are zoned for different elementary schools: Stonehaven E.S. serves the Stonehaven section, Stonebridge P.S. covers parts of Copper Hills, and Poplar Bank P.S. serves Wyndham Estates. All three feed into Newmarket High School for secondary education. If elementary school zoning is a priority, verify the address using the YRDSB School Locator before making an offer, as school boundaries can change from street to street.

Sacred Heart Catholic High School is the Catholic secondary option, scoring 7.2 out of 10 on Fraser and ranking 178th in the province. That puts both secondary options in this catchment above the provincial midpoint, which is unusual — most neighbourhoods have one strong school and one average one. Here, both are above average.

Inside Tip

There are two notable data patterns to consider before making an. First, the condo-townhouse segment, with an average price of $834,000 and a 98% sale-to-list ratio, offers the most accessible entry into the Stonehaven-Wyndham catchment. Buyers benefit from the same Newmarket High School zoning, Magna Centre access, and proximity to 404 at approximately half the price of detached homes. With 80% absorption and 39 days on market, inventory is sufficient for careful selection, yet demand ensures that well-priced units do not remain unsold for long. For those prioritizing schools but not seeking a $1.5 million detached home, this segment is particularly attractive.o watch.

Second, Copper Hills is often overlooked by out-of-town buyers. As the newest and most premium area within Stonehaven-Wyndham, its homes may not be immediately apparent in MLS searches, as they are listed under the broader neighbourhood name. Buyers seeking luxury in Newmarket should ensure they consider Copper Hills, which represents the top of the market. However, as these homes are relatively new, resale values have less historical data for comparison, so pricing should be approached with care.

Similar Neighbourhoods to Consider

If you are considering Stonehaven-Wyndham, three other Newmarket neighbourhoods are also worth exploring:

Armitage for buyers who want the same Newmarket High School catchment with a quieter, more established character. Armitage ran a Q4 2025 average of $1,151,000 on 7 sales with a 98% SP/LP — the tightest sale-to-list in Newmarket, tied with Gorham-College Manor. The housing stock is 1980s and 90s-era brick detached homes, with the Saint Andrews Valley Golf Club providing 200 acres of protected green space along the eastern and southern edges. You're trading Copper Hills' newness for Armitage's character and saving $160,000 on the average detached purchase.

Gorham-College Manor for buyers who want the widest range of housing options in Newmarket. Gorham-College Manor posted an average of $933,756 with 25 sales and a 60% detached SNLR—the highest absorption rate for detached in the city. Victorian homes, bungalows, split-levels, townhouses, condos, all on the same streets. Pickering College, the private JK-12 day and boarding school, is the anchor institution. If a private school is part of your plan, this is the neighbourhood.

Glenway Estates for buyers who want the Stonehaven-Wyndham scale at a lower price point. Glenway Estates averaged $1,078,294 in Q4, with Upper Canada Mall, the Ray Twinney Recreation Complex, and the Newmarket Bus Terminal all within the neighbourhood. The housing stock ranges from condo townhouses at $528,000 to detached homes at $1,417,000, so the budget flexibility is the widest in Newmarket. The trade-off is the school catchment — Alexander Muir P.S. at 7.6 Fraser is solid, but it's not Newmarket High School.

Stonehaven-Wyndham — Where the Market Goes From Here

Newmarket's spring 2026 numbers are showing real momentum. April posted 85 sales at an average of $998,202 and a median of $944,000, with SP/LP climbing to 101% and days on market dropping to 24. That 101% SP/LP is a meaningful signal — homes are selling above asking price on average for the first time in months. The detached segment city-wide reached 102% SP/LP in April, meaning detached buyers across Newmarket are competing and paying over list price.

What does that mean for Stonehaven-Wyndham specifically? In Q4, the detached market here ran 28% absorption and 97% SP/LP. That was buyer-friendly territory. If the spring tightening that hit Newmarket as a whole reaches the southeast luxury corridor, the negotiating window that was open in Q4 narrows. The semi-detached segment, which was already at 120% absorption in Q4, is likely to tighten further. And the condo-townhouse segment, at 80% absorption, could cross into seller 's-market territory if the spring demand wave reaches that price point.

In my assessment, the Stonehaven-Wyndham detached market above $1.5 million will be the last segment in Newmarket to experience the effects of the spring market shift, as luxury properties typically lag behind broader trends by one or two quarters. Buyers in this range are generally less sensitive to interest rates, more patient, and have more options. However, entry-level segments such as semi-detached and condo townhouses are already experiencing tightening conditions. If your budget is below $900,000, the favourable conditions observed in Q4 may be coming to an end.
