Cornell (2006 population estimated 12,000) (Census Tract Number 5350400.01)  is a new community being developed in northeast Markham, Ontario and bounded by Highway 407, 16th Avenue, Ninth Line, and the Don Cousens Parkway.
Cornell was conceived in the 1990s planning process by the town of Markham. Unlike other Markham communities, Cornell is a planned community.
One of the original settlers was Christian Reesor. He and his family settled in Cornell. Their original homestead was on Reesor Road. The name ‘Cornell’ derives from the maiden name of the wife of Christian Reesor’s youngest son, who continued to live at the family homestead.
Cornell's name was selected in the 1990s from a suggestion by local lawyer Paul Mingay. Mingay's family roots can be traced back to Susan Emily Cornell, a descendant of William Cornell, settler of Scarborough, Ontario. Later Cornells settled in Markham, Ontario and married into the Reesor family. William Cornell immigrated to Canada from Rhode Island is a distant relative of Ezra Cornell, founder of Cornell University.
Most of the houses are townhomes, semi-detached, or detached houses with garages at the rear. The communities are built with central amenities in order to contain suburban sprawl. Cornell was seen by the Markham Town Council as a way to deter the ongoing sprawl by encouraging residential density. The community, particularly Cornell Village, is an example of new urbanism, designed as a walkable neighborhood with a variety of housing types and retail. Cornell Village, between Highway 7 and 16th Avenue, is fully populated with medium density residential. The southern section of Cornell (south of Highway 7), however, is not populated, and remains as a wild field and a farm. In 2012, the city of Markham completed Fire Station 99 to serve the area.
Subdivisions within Cornell
Cornell can be further separated by development phases:
- Grand Cornell - locate near Highway 7 and 9th Line and built by builders H&R, GreenPark and CountryWide
- Upper Cornell - located near 16th Avenue and 9th Line and built by builders Aspen Ridge or Beaverbrook
- Cornell Village - located between 16th Avenue and Highway 7 along 9th Line to Cornell Center Blvd; built by builders Mattamy or Ballantry
- Cornell Rouge - Located east side of Cornell Center Blvd to Donald Cousens Way between 16th Avenue and Highway 7; built by builders of Madison Homes and Forest Hill
The remaining portions of Cornell are still non-agricultural grasslands, but it will slowly disappear with further development.
In 2004 there was a plan to create a residential and retail development called Cornell Town Centre along the southern end of Cornell. This plan never materialized and most of the area has since been re-developed as residential homes. The man-made recreational Cornell Lake is now a series of ponds that carries the waters of Little Rouge Creek in Grand Cornell development.
The development is not far from the proposed Pickering Airport and once one of the sites for landfills in the Greater Toronto Area. While runway 10R/28L will still be within Pickering, the southwest end of the property will be located north of 16th Avenue and 9th Line. Toronto/Markham Airport is located north in Dickson Hill, Ontario. This area is mainly served by Toronto Pearson International Airport for civilian air travel.

The Markham Stouffville Hospital Terminal is a temporary terminal serving Cornell and the nearby areas. The York Region Transit authority is currently building a permanent bus terminal, Cornell Terminal, located at Donald Cousens Parkway and Highway 7. The temporary terminal at Markham Stouffville Hospital will shut down upon completion of the new terminal. The completion date is not yet to be known.
There is also one VIVA line serving the area, Viva Purple. Viva Purple terminates at the Markham Stouffville Hospital as well, with plans in the future stretching to Cornell Permanent Terminal. Viva Green, currently ending at McCowan Vivastation, is also planned to extend its service into Cornell via the Highway 7 corridor.

- Little Rouge P.S: located just in Upper Cornell. Students living in Grand Cornell, Cornell Rouge, Cornell and Upper Cornell and students from the farmlands northeast of Markham attend Little Rouge Public School.
- Black Walnut P.S: The significance of the school’s name is from the fact that Black Walnut trees grow best in deep, fertile soil. When settlers came to Markham, more than two centuries ago, they saw Black Walnut trees growing. They knew this was a good sign that they had found an area that would be good for farming. More than 65 German Pennsylvanian families, many of them Mennonites, came to Southern York Region because of, indirectly, the Black Walnut.
