Community overview
Stonehaven-Wyndham is one of the communities TRREB (Toronto Regional Real Estate Board) defines within York Region – Newmarket. It sits in the southeast corner of Newmarket, across St. John's Sideroad from Aurora. Two north–south arterials, Bayview Avenue and Leslie Street, run through the community, and Highway 404 borders it on the east. Neighbourhood names you will see on maps include Stonehaven, Wyndham Village, Copper Hills and the Bogarttown area (names from OpenStreetMap labels, for orientation only).

School boundaries are set by street address and may be adjusted temporarily as enrolment grows; a school being inside the community does not mean every address is in its boundary. Please confirm with the YRDSB school locator and the YCDSB school locator. This page does not rank schools.

Shopping and daily life
Stonehaven Centre, a small retail plaza, is in the middle of the community (per OpenStreetMap). Larger supermarkets and malls are outside the community; Ming is happy to walk you around in person when you view homes.
Housing types
(To be added: the mix of existing home types will be written once public census data that maps cleanly to this community's boundary is available. Statistics Canada's 2021 Census is published by dissemination area and census tract, which do not line up with TRREB's Stonehaven-Wyndham market boundary, so this page does not estimate the housing stock.) The by-type figures in "Recent sales and home prices" below are sales in that quarter, not the housing stock.
Recent sales and home prices
This section shows two kinds of data published by TRREB; please read them separately. The first is actual sales summarized in the quarterly community report. The second is the monthly MLS® Home Price Index (HPI) benchmark price, which describes a typical home. The quarterly report and the HPI are measured differently and cannot be added together. Where there are two or fewer sales, TRREB does not publish some price measures. These figures are for reference only and are not a guarantee of the value of any property.
This page does not show current listings or individual sale records. For recent sales on a particular street or home type, or a value estimate for your home, please contact Ming.

Source: the Stonehaven-Wyndham by-type page of the same TRREB Q2 2026 Newmarket community report. 32 of the 41 sales this quarter were detached homes. By-type average and median prices are taken from the chart labels in thousands (e.g. $1,588K), not exact to the dollar; sales and new listings are whole numbers from the charts. For home types with two or fewer sales, or none, prices and some ratios are not published per the report's convention and are shown as "—".
Compared with Newmarket (Q2 2026, all home types)
All community figures below are taken directly from the summary table of the same quarterly report. Stonehaven-Wyndham's average price of $1,422,854 and median price of $1,368,000 this quarter were both the highest of the nine communities listed; the next-highest median was Glenway Estates at $1,246,000. The combined row adds up the nine rows for sales, dollar volume, new listings and active listings; the combined average is combined dollar volume ÷ combined sales, not a town-wide average published separately by TRREB. Median price, sold/list price and days on market cannot be summed from community figures, so the combined row omits them. The community's average price is $389,382 above the combined average.

Source: summary table of TRREB's Q2 2026 Newmarket community report (publicly released). *Combined sales, dollar volume, new listings and active listings are the sum of the nine rows; the combined average of $1,033,472 is $285,238,178 ÷ 276, rounded to the dollar. Active listings are a point-in-time figure from the report. The report notes that quarterly community statistics may not match the quarterly sums of earlier TRREB publications.
MLS® Home Price Index (HPI) benchmark prices
TRREB's October 2026 HPI public tables include Newmarket's town-wide composite and by-type benchmark prices, but no separate row for Stonehaven-Wyndham, so this page lists only the town-wide figures and does not make up a community-level benchmark.
| Area | Home type | Benchmark price | Index | Year-over-year |
|---|---|---|---|---|
| Newmarket (town) | Composite | $960,700 | 306.4 | -7.79% |
| Single Family Detached | $1,082,400 | 299.2 | -6.62% | |
