In every real estate market, certain neighbourhoods outperform the broader city, not because of luck, but because of the specific combination of school quality, infrastructure investment, development activity, lifestyle infrastructure, and market timing that converges to make them the right place at the right moment. In Markham’s 2026 market, two communities are generating the most qualified buyer attention: Unionville and Cornell Rouge.
REMAX York Region’s 2026 market outlook names Unionville’s new construction of single-family homes in the Union Glen and Cornell Rouge areas as one of the top three most desirable neighbourhoods in all of York Region for 2026. Michael John Lau, top real estate agent in Markham Ontario, works in both communities daily. Here is the current picture in each.
Unionville — Heritage Prestige at a 2026 Entry Point
Unionville is Markham’s most prestigious established community. Main Street Unionville — a heritage streetscape dating to the 1790s — hosts the Unionville Music Festival, the Unionville Festival, and year-round boutique retail and dining. Toogood Pond Park’s 82 acres of trails and waterfront. Unionville High School, Bill Crothers Secondary School, and a K-to-12 school ecosystem that consistently ranks among Ontario’s best. Unionville GO Station providing direct downtown Toronto access.
2026 Pricing Reality: Detached homes that peaked above $2,500,000 in 2022 are transacting in the $1,800,000 to $2,200,000 range for comparable properties in early 2026 — a 12% to 18% correction from peak. This is the deepest discount to peak pricing Unionville has offered since 2018.
For buyers who were priced out of Unionville during the 2021 to 2022 peak — or who watched from the sidelines as prices exceeded their reach — 2026 represents the first genuine access point in years. The lifestyle premium commanded by Unionville’s heritage character, school quality, and Main Street vibrancy does not depreciate. The price has.
The Union Glen new construction development is also bringing premium new freehold product to the community’s newer western precincts. For buyers who want new construction quality in the Unionville school catchment — Unionville High School and Bill Crothers Secondary — Union Glen offers an alternative to the resale market with new build specifications.
For downsizers who want to stay in the community they love, the Tridel-built Circa I at 33 Cox Boulevard and Circa II at 23 Cox Boulevard provide luxury condominium living with indoor pool, golf simulator, sauna, billiard room, 24-hour concierge, and underground car wash — walking distance to Main Street Unionville and Toogood Pond Park.
Cornell Rouge — New Construction at the Edge of Rouge National Urban Park
Cornell Rouge by Madison Homes at 16th Avenue and Donald Cousens Parkway is Markham’s newest master-planned community and the most significant freehold new construction launch in Markham’s eastern corridor in several years. Freehold townhomes from $1,599,990 and detached homes from $1,999,990 sit directly adjacent to Rouge National Urban Park — Canada’s first urban national park — in an enclave that combines the established Cornell community’s amenities with premium new construction and extraordinary natural surroundings.
Cornell Rouge buyers receive the full benefits of the established Cornell community infrastructure: the Cornell Community Centre (129,000 sq ft), Markham Stouffville Hospital within minutes, Bill Hogarth Secondary School, Cornell Bus Terminal, and the entire walkable New Urbanism-designed Cornell streetscape. They add to this the nature premium of the Rouge Park adjacency and the new construction advantage of a home built to 2025 and 2026 Ontario Building Code standards.

Unionville is attracting luxury move-up buyers who have been equity-building in Markham’s mid-tier communities for a decade and are ready to make the prestige move. It is also attracting newcomer families from Hong Kong and mainland China who specifically target Unionville for its school quality and heritage lifestyle character. And it is attracting downsizers who want to stay in the community they love, transitioning from a large detached to a Circa I or II condo.
Cornell Rouge is attracting families making their first or second move-up purchase who want new construction quality, Rouge Park access, and Cornell’s established community infrastructure in a single address. It is also attracting investors who understand that new construction in established communities with strong rental demand fundamentals, the Cornell hospital workforce, generates solid long-term returns.
The HST Rebate — Why Pre-Construction Cornell Rouge Makes Sense in 2026
For pre-construction purchases at Cornell Rouge signed before March 31, 2027, the HST rebate program announced by Premier Ford applies to eligible units. Consult with Michael John Lau and Neeraj Moolchandani, top real estate agent in Markham Ontario, to understand exactly how the rebate applies to specific Cornell Rouge configurations and purchase prices. On a $1,599,990 townhome, understanding the exact rebate eligibility and structure is a material financial question that requires professional guidance — not an assumption.
