Unionville, Markham - The Complete Neighbourhood Guide

By Shawn Zigelstein, Broker | Team Zold, Royal LePage Signature Realty | October 2026

Updated October 4, 2026 with TRREB Q2 2026 community data.

Unionville, Markham recorded 159 home sales at an average price of $988,479 in Q2 2026, with the mix of homes sold shaping that figure. That average describes the properties that changed hands. It isn't the value of a typical home or evidence that the same property appreciated.

Apartment sales have a substantial influence here. If you're picturing a detached home near Main Street Unionville, start with the detached figures and the actual address. An apartment search needs its own comparisons. For the wider city context, visit our Markham community page.

Where is Unionville in Markham?

Start your local orientation with Main Street Unionville, Carlton Road and Toogood Pond. These give you a practical introduction to the historic-area setting. But the Unionville reporting area used by TRREB extends beyond the historic Main Street district. The homes behind its market figures shouldn't all be pictured on the same stretch of street.

Keep the station on a separate part of your map. Unionville GO is at 155 YMCA Boulevard, and it's a destination to evaluate from the home you're considering. A neighbourhood name doesn't tell you how that first part of the journey works.

When you shortlist a property, place the actual address alongside the places you'll use. That could mean the pond and Main Street, a school you've confirmed with the board, or the station. Postal, heritage and market-reporting labels serve different purposes. Use the Unionville name to begin your search, then let the address determine which version of daily life you're buying into.

What do Unionville's Q2 2026 market figures tell you?

TRREB recorded 159 Unionville sales in Q2 2026 at an average price of $988,479. The median was $735,000. The median marks the middle of the sold group, while the average combines all of its prices. Neither gives you a valuation for an unexamined home. Start with the quarter's activity, then separate the housing types.

Source: TRREB, Markham Community Housing Market Report, Q2 2026, Unionville summary, printed page 2 (PDF page 3). Calculated SNLR = 159 / 439 x 100 = 36.2%. Inventory proxy = 216 / (159 / 3) = 4.1 months; rounded to one decimal, based on reported active listings and quarter-average sales pace, not an official TRREB MOI series or forecast.

The calculated sales-to-new-listings ratio is 36.2%. It divides the quarter's 159 sales by its 439 new listings. Those totals aren't a matched group of listings followed from introduction to outcome, so you can't use the ratio to say which newly listed homes sold or failed to sell.

The 4.1 months inventory figure is a different calculation. It divides the reported 216 active listings by the average monthly sales pace across the quarter. Think of it as an illustration of supply at that pace. It isn't an official TRREB months-of-inventory series or a forecast of how long those properties will take to sell.

The 30 average days on market describes marketing time for recorded sales, not closing time or the age of unsold listings. And the 99% sale-to-list-price ratio doesn't promise you a discount. These figures describe a quarter's transactions; they don't establish whether prices are rising or falling.

How do prices differ by property type in Unionville?

The distinction that matters most is between the Condo Apartment average of $639,000 from 96 sales and the Detached average of $1,713,000 from 45 sales. Apartment transactions have a substantial influence on the overall result. If you're searching for a detached home, the community average brings a large group of different properties into your comparison.

Even the matching property-type average is a starting point. It describes the homes sold within that category during Q2 2026, rather than a price that applies to every home now available.

Source: TRREB, Markham Community Housing Market Report, Q2 2026, Unionville charts, printed page 36 (PDF page 37). Property-type prices are rounded to the nearest $1,000 in the report. n/r means not reported, not zero; TRREB suppresses some metrics with two or fewer transactions. The overall sample is a single quarter, not a trend series. Thin segments: Semi-Detached (1 sales), Att/Row/Townhouse (5 sales). Zero-sales categories: Other. Zero transactions do not establish absence of housing stock. Other remains the report's category; it is not a verified building or tenure description.

Read the smaller categories cautiously. Semi-Detached had only 1 sale and Att/Row/Townhouse had 5 sales. Both are thin samples and unreliable for trend claims. The townhouse average of $1,251,000 describes that small sold group; it isn't a dependable price range for your search.

Condo Townhouse recorded 12 sales at an average of $942,000. Keep that category separate from Att/Row/Townhouse when you compare the figures. The report's labels don't establish every individual property's ownership arrangements, so check those in the property documents.

The n/r cells mean not reported, not a zero price. Other recorded 0 sales, which doesn't establish that such housing is absent. Property-type prices are also rounded to the nearest $1,000 in the report, while the overall average is shown in whole dollars. Preserve those distinctions when you compare a listing with this snapshot. Differently composed groups of sold homes can't establish a premium or discount for equivalent properties.

What kinds of homes should you compare in Unionville?

Your first decision is the housing form you actually want. The quarter recorded sales in Detached, Semi-Detached, Att/Row/Townhouse, Condo Townhouse and Condo Apartment categories. That gives you several forms to investigate, but a sales report isn't a census of all the homes that exist here.

For a Main Street detached-home search, focus on the individual property and how its location connects with the historic-area setting. For an apartment search, compare the unit and its ownership and maintenance obligations. A shared neighbourhood name won't make those choices interchangeable.

Ask yourself what you want to take responsibility for and what you need from the space. Then check how the particular home meets those preferences. Don't infer its condition, construction era or tenure from the category label alone.

The useful comparison is between homes you could realistically choose for the same purpose. Once you've settled that question, the matching market figures and property documents become much more useful than the community average on its own.

Which schools should Unionville buyers check?

Unionville P.S., Unionville H.S. and St. Augustine Catholic High School are schools to investigate as you build your shortlist. Their confirmed locations give you places to check; they don't establish that a particular Unionville home qualifies for attendance. These are local or regional examples, rather than a complete catchment list.

Sources: the official school/board profiles and contact pages, checked October 4, 2026; YRDSB School Locator. These are local or regional examples to investigate, not a complete or guaranteed catchment list. The school names and postal communities do not define the TRREB reporting boundary. No ranking or attendance promise is asserted.

For the public system, use the YRDSB School Locator with the exact property address and confirm the intended school year and program with YRDSB. If a specific school is central to your move, do that work before you treat a listing as a match. A school name or postal community isn't a substitute for an address check.

For the Catholic secondary option, start with the St. Augustine Catholic High School contact information and confirm the applicable requirements with the school or YCDSB. Check the address, entry year and program for your child rather than carrying over an assumption from a different home.

Keep the questions practical: which school would apply to this address, which program are you seeking, and what confirmation do you still need? The locations and listed grades above answer only part of that process. They don't rank the schools or promise placement.

How can you plan a commute from Unionville?

Unionville GO at 155 YMCA Boulevard is a regional option to evaluate. Start with the Unionville GO station information, then work backward to the home you're considering. Being interested in rail service and having a workable journey to the station are separate questions.

Use the YRT system maps to investigate the local part of the trip. Check the day you would travel, the connection from home and the final leg at your destination. Then plan the return journey. A route that looks useful for your outward trip still needs to fit the time you expect to come home.

Test that complete journey from a candidate property, using current operator information. Include the access arrangements you would actually use rather than assuming you'll walk to the station from every Unionville address.

If you're comparing homes, repeat the same exercise for each address. The station's presence gives you an option to investigate; it doesn't establish the nearest station, a particular service frequency or a journey time for the whole community. Let your own planned trip decide the fit.

What does everyday life in Unionville offer?

For outdoor stops, Toogood Pond at 218 Carlton Road provides a pond-space destination with listed washrooms. Crosby Park at 210 Main Street Unionville lists a playground, soccer and a ball diamond. Visit the places you'd use and check current facility and trail notices before you plan around them.

For organised recreation, Milliken Mills Community Centre is at 7600 Kennedy Road, south of 14th Avenue. Its listed facilities include a pool, library, ice, dance and meeting space, and indoor fields.

Treat the centre as a local or regional trip to test from the actual home. These destinations don't all have the same relationship to every Unionville address, and their listings aren't promises of current access. Separate the nearby stops you would use routinely from trips you'd plan more deliberately.

What should you consider before buying in Unionville?

Choose between detached and condominium forms early in your search. That decision will help you select relevant sales comparisons and ask useful questions about maintenance. If you're open to either, keep separate shortlists so that an appealing community average doesn't blur the differences between the properties.

Check the documents that apply to the home. For a condominium, review the condominium documents and the ownership and maintenance obligations rather than assuming the physical form tells you everything. For a property where heritage status may be relevant, check the City's maps and register. The existence of a Unionville heritage district doesn't designate every home in the similarly named TRREB area.

Bring the address into the rest of your decision too. Confirm school eligibility if it matters to your household, and test the first leg to Unionville GO if rail is part of your plan. A listing can suit the housing form you want and still leave you with a daily journey you wouldn't choose.

Use the quarter's figures to frame your questions, not to set a promised negotiation outcome. What you need next is a property-specific comparison and a clear understanding of the home.

Insider Tip

Tour the Main Street Unionville and Toogood Pond area, then visit the station-area destination as a separate stop. After that, return to your candidate home's address and compare how it connects with each. This helps you distinguish the setting you enjoy visiting from the trips you'd make routinely.

If the historic-area setting is your priority, examine that relationship directly. If the station is central to your workday, give the journey there the same attention as the home itself. The Unionville name can introduce you to both places, but it doesn't guarantee that a particular property gives you the access you have in mind.

Which other Markham neighbourhoods should you compare?

Village Green-South Unionville and Berczy are useful alternatives for a Markham search organised around housing form. Compare the kinds of homes that sold before you compare their overall averages.

Village Green-South Unionville recorded 15 sales at an average of $1,346,990 in Q2 2026. Its sold mix was 8 Detached, 3 Semi-Detached, 3 Att/Row/Townhouse and 1 Condo Apartment. Every one of those property-type samples is thin and unreliable for trend conclusions.

Berczy recorded 54 sales at an average of $1,250,316. Its mix was 25 Detached, 7 Semi-Detached, 21 Att/Row/Townhouse and 1 Condo Apartment. The semi-detached and apartment samples are thin here too.

Those mixes differ from Unionville's apartment-heavy sales activity. The overall figures don't rank the communities by affordability or establish what an equivalent home would cost in each. If you want a detached home, compare detached properties that suit your needs. If you're considering a townhouse, distinguish the category and the actual ownership arrangements. Use these communities to broaden the homes you examine, then assess the particular properties rather than treating the averages as competing price tags.

Is Unionville the right fit for your next move?

Unionville is worth considering if you're prepared to match the home type with the setting and daily trips you actually want. Apartment sales substantially influence the community average, so a Main Street detached-home search and an apartment search need different comparisons from the outset.

If you're weighing Unionville, Village Green-South Unionville and Berczy, let's start with the properties that fit your life. Bring your preferred home type, maintenance preferences, school requirements and commute plans. We can work through the comparisons around those priorities and the actual addresses.
