Cornell vs Box Grove
The short answer: Cornell and Box Grove are neighbours across Highway 407 in east Markham, and their detached prices are closer than most people expect: a median of about $1,278,000 in Cornell and $1,350,000 in Box Grove in the second quarter of 2026. The real difference is the kind of home and the kind of street. Cornell is a walkable, planned community with rear-lane towns, semis and detached homes, the hospital, and the Viva Purple terminal. Box Grove is a quieter, car-oriented pocket of post-2000 brick detached homes with front garages, many with separate basement entrances, right beside Rouge National Urban Park. Choose Cornell for choice and walkability. Choose Box Grove for a conventional detached home and the park next door.
A New Urbanist community built from 1997 between Highway 407 and 16th Avenue, with porches, rear lanes, coach houses, the hospital, and Cornell Centre still growing.
A community of mostly post-2000 brick detached homes and freehold townhomes south of Highway 407, east of Ninth Line, with Rouge National Urban Park as its back garden.

Prices
What a Home Costs in Each
Detached figures are from TRREB's Q2 2026 community report. Other types are shown as September 2026 medians with the number of sales behind them.
| Home type | Cornell | Box Grove | Note |
|---|---|---|---|
| Detached | Median $1,278,000 (Q2) Sept 2026 median $1,370,000 |
Median $1,350,000 (Q2) Sept 2026 median $1,349,000 |
Cornell's September figure is one sale |
| Semi-detached | About $940,000 (4 sales) | About $960,000 (1 sale) | Close |
| Townhouse | About $895,000 (4 sales) | About $840,000 (1 sale) | Cornell has far more choice |
| Condo | About $620,000 (1 sale) | Very few condos | Cornell only |
Sources: TRREB community report Q2 2026; Wahi neighbourhood data, September 2026 medians. Medians on one to four sales can swing widely month to month.
For detached homes, the two communities sit within about $70,000 of each other on the Q2 2026 medians. Box Grove ran a little higher, largely because almost everything there is a full-size detached home, often with a basement entrance, while Cornell's detached homes include narrower rear-lane lots.
The bigger difference is the entry point. Cornell's all-types median was $947,500 because it offers freehold and condo townhomes, semis and condos. Box Grove's was $1,117,500 because it has few smaller homes to bring the average down. If your budget is under $1 million, Cornell gives you far more to choose from.
Lots backing onto the Rouge valley sit in a different bracket. In Box Grove, Michael's sellers at 59 Smoothwater Terrace sold their ravine-lot home for $1,650,000, $150,000 over asking and about $280,000 above the community's Q2 detached average.
Both communities appeal to buyers who want room for family or rental income, but the homes are built differently. Many Cornell lots have a coach house, a suite above the rear garage with its own entrance. Many Box Grove homes were built with a separate side or walk-up basement entrance, which suits a lower-level suite.
Ontario now permits additional residential units on most residential lots, but every suite still needs the right permits from the City of Markham. Before you pay for income potential, confirm whether an existing suite is registered and legal.
The Deeper Comparison
How Daily Life Differs
Price is only one line. These are the differences that shape a normal week in each community.
Housing stock and street design
Homes face the street with porches; garages sit on rear lanes. Freehold and condo townhomes, semis, detached homes on narrower lots, coach houses on many streets, and condo towers planned near Cornell Centre.
Mostly brick detached homes built after 2000, typically four bedrooms with nine to ten foot main-floor ceilings and many separate basement entrances, plus 25 ft freehold townhomes. Conventional front garages and driveways.
Cornell suits buyers who want variety and a walkable street. Box Grove suits buyers who want a conventional detached home with a driveway.
Commute and transit
Cornell Terminal (opened 2022) is the eastern end of Viva Purple, with YRT routes and GO buses. Mount Joy GO is a short drive north, and Highway 407 runs along the community's south edge.
Highway 407 at Ninth Line is right at the community's edge, with Markham GO and Mount Joy GO a short drive away. YRT service is limited, so most households rely on a car.
For transit, Cornell is clearly stronger. For drivers, they are close to even.
Parks and everyday amenities
Cornell Community Centre and Library (pool, gym, running track), Cornell Community Park, Grand Cornell Park and Oakmoor Pond, plus shops along Highway 7.
Rouge National Urban Park is next door, including Bob Hunter Memorial Park. The Copper Creek SmartCentre (Walmart) and Boxgrove Centre (Longo's) cover groceries, and the Box Grove Community Centre sits in an 1870 schoolhouse.
Cornell has more amenities inside the neighbourhood. Box Grove has the larger natural setting.
