Checking YCDSB's Markham school list, there is no YCDSB school inside this community; use the YCDSB school locator to find the designated Catholic school.
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. School names and grades are from the YRDSB and YCDSB Markham school lists, with locations checked by address; schools too close to a community boundary to place with confidence are not listed. This page does not rank schools.

Getting around
- Bus: there is no Viva rapid-transit stop or GO train station in the community; service is by regular YRT buses.

Viva Purple and Viva Blue routes and stop names are from YRT's route maps, with stop locations at OpenStreetMap road intersections; GO station locations are per OpenStreetMap.

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 Aileen-Willowbrook 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 Aileen-Willowbrook by-type page of the same TRREB Q2 2026 Markham community report. Of the 21 sales this quarter, 7 were detached homes. By-type average and median prices are taken from the chart labels in thousands (e.g. $1,390K), 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 Markham (Q2 2026, all home types)
All community figures below are taken directly from the summary table of the same quarterly report. Aileen-Willowbrook's average price this quarter was $1,016,214 and its median price $900,500; among the 39 communities in the table with price figures, it ranked number 33 by average price and number 34 by median price (highest first). The combined row adds up the rows that have figures for sales, dollar volume, new listings and active listings; the combined average is combined dollar volume ÷ combined sales, not a city-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 $142,516 below the combined average.

MLS® Home Price Index (HPI) benchmark prices
TRREB's October 2026 HPI public tables include Markham's city-wide composite and by-type benchmark prices, but no separate row for Aileen-Willowbrook, so this page lists only the city-wide figures and does not make up a community-level benchmark.

| Markham (town) | Composite | $1,037,300 | 286.3 | -6.89% |
