The Short Answer
What is Unionglen in Markham? Unionglen is a major new pre-construction master-planned community at Kennedy Road and Major Mackenzie Drive East in north Markham — where Unionville meets Angus Glen.

New freehold home communities in Markham's established, sought-after neighbourhoods are increasingly rare — which makes Unionglen genuinely notable. This large master-planned community is bringing brand-new detached homes and townhomes to a prime north Markham location.

Where Unionglen Is
Location is Unionglen's headline strength. It sits at Kennedy Road and Major Mackenzie Drive East in north Markham — directly across from the prestigious Angus Glen community and golf club, along the northern edge of historic Unionville. This places residents in one of Markham's most desirable, established, and high-performing real estate areas, combining a peaceful, green setting with excellent connectivity. Highways 404 and 407 are minutes away, and GO Transit (Mount Joy) is nearby.
What Makes Unionglen Notable
Rare new freehold supply in an established area
The biggest draw: brand-new freehold homes — you own the home and the land, with no monthly condo fees. New low-rise freehold supply in Markham's established, sought-after neighbourhoods is genuinely limited, which makes a community of this scale and location stand out for both families and investors.
Detached homes and diverse townhomes
Unionglen offers a range of home types — single-family detached homes plus multiple townhome styles (traditional, courtyard, and others) — providing options across needs and budgets, all in a new-build community. This variety suits move-up families, first-time freehold buyers, and downsizers alike.
Seven established GTA builders
The community is being built by seven of the Greater Toronto Area's most established, award-winning homebuilders — a roster that brings decades of experience and reputational weight to the development.
Top school catchment
Unionglen falls within the catchment of highly ranked schools, including Pierre Elliott Trudeau High School (one of Ontario's top-ranked secondary schools), with access to other strong schools nearby — a major draw for families prioritizing education.
Prestige location and lifestyle
Directly across from Angus Glen Golf Club (a championship course that has hosted the Canadian Open and Pan Am Games), surrounded by extensive parks, trails, and greenspace, and near the Angus Glen Community Centre (arena, sports centre, library, pool), Unionglen offers an upscale, amenity-rich lifestyle in a coveted setting.
Neeraj Moolchandani on Buying Pre-Construction Freehold
Neeraj Moolchandani, REALTOR® at Kaizen Real Estate, treats a pre-construction purchase as a contract decision as much as a property decision. Closing adjustments, occupancy provisions, assignment restrictions, and the builder's right to modify plans are all in the agreement, and they routinely surprise buyers who focused on the floor plan. A real estate lawyer review during the rescission period is not optional here.
On timing, Neeraj is candid that a completion window several years out carries genuine uncertainty. Delivery dates move, and a buyer who needs to be in a home by a specific date should not depend on a pre-construction closing to get there. For buyers with flexibility, a freehold community of this scale in an established catchment is a rare opportunity. For buyers on a fixed timeline, resale is usually the better answer.
Who Unionglen Suits
Families
Top schools, greenspace, community amenities, and brand-new freehold homes in a safe, established area make Unionglen highly appealing to families — exactly the profile that values this location.
Move-up buyers
Buyers looking to move up into a new detached or larger freehold home in a prestigious Markham setting will find Unionglen a compelling option.
Investors
With limited new freehold supply in established Markham neighbourhoods, strong school catchments, and the area's enduring demand, Unionglen presents a consideration for investors focused on long-term fundamentals in a premium market. (As always, pre-construction investment carries its own considerations — do your due diligence.)
Considerations for Pre-Construction Buyers
Buying pre-construction is different from resale. It involves considerations like deposit structures, occupancy and closing timelines, development levies and closing costs, the builder's contract terms, and the fact that you're buying based on plans rather than a finished home. There's genuine opportunity in pre-construction, but it requires understanding these factors carefully. Working with a knowledgeable REALTOR® and lawyer to review everything is essential — and confirm all current details (pricing, floor plans, availability, timelines) directly, as they change.
