History and development

Before the Leas

The general area of Toronto had been inhabited by various Natives at least as early as 3000 BCE, when the Laurentian peoples moved south into the area just east of Toronto. The first European known to travel to the area was Étienne Brûlé, who passed through the area in the early part of the seventeenth century. Surveying and settlement by Europeans began in earnest in the 1780s, with the influx of Loyalists fleeing the American Revolution.

Lea family settles Lot 13

John Lea immigrated to York, Upper Canada in 1819, coming from Philadelphia. He had come to the United States from England only a year previous. He purchased Lot 13 in the third concession from Alexander McDonnell on January 23, 1820 and settled there with his family. John Lea had three children - William, John Jr. and Mary. In 1851, William Lea bought land just south of his father's farm, and began constructing a large, octagonal brick house, which he named "Leaside". The house was completed in 1854. The building served not only as a home for Lea's family, but after he became a Magistrate in the County of York, soon served as a post office as well. The property became the possession of his son Joseph upon his death in 1893.

Railways come to Leaside

In the 1870s, the Ontario and Quebec Railway Company purchased a few acres of land on the south-east corner of William Lea's property to run its railway across. The Ontario and Quebec Railway Company encountered financial difficulties in 1884, and leased part of its railway, including the section of track running through Leaside, to the Canadian Pacific Railway for 999 years. The Canadian Pacific Railway decided to establish a maintenance stop and a sliding by-pass on the railway on the land purchased from William Lea, which was attractive because it was uniformly flat. The station was completed in September 1884 and named "Leaside" in honour of William Lea. In 1892 a junction was built in the Leaside area, and a railway line was constructed south along the Don towards Union Station.  

Leaside: a model town

In 1912, William Mackenzie and Donald Mann, the owners of the Canadian Northern Railway hired planner Frederick Todd to plan development for a community to be built around a maintenance yard for their railway. Mackenzie and Todd founded the York Land Company to purchase land for such a town. The company purchased over 1,000 acres (4.0 km2) most of the third concession and some land north of Eglinton Avenue. The purchased lands extended from the railway tracks in the south to three farms north of Eglinton Avenue, from Leslie Street in the east to Bayview Avenue in the west. The town of Leaside was planned by Todd for the company, which put its name to many of the local streets; Laird Drive, Hanna Road and Wicksteed Avenue all bear the name of Canadian Northern Railway company executives. The new community was planned with commercial areas, residential areas and a town centre west of Laird Drive, and space was laid out east of Laird Drive for industrial development. The goal of the company was to create Leaside as a new upper class residential area of Toronto, the "New Rosedale". The developers first approached the town of North Toronto, hoping that North Toronto would annex the area and provide services such as streets, sewers and public transportation. The town council of North Toronto refused A similar request to the city of Toronto was met with a similar reply. With their attempts to include Leaside within another city or town rebuffed, Colonel Davidson and Randolph McRae applied to the province of Ontario to incorporate Leaside as a town.

The Town of Leaside was officially incorporated on April 23, 1913. The population of Leaside was 43 individuals. The Canadian Northern Railway company approved Todd's town plan on May 8, 1913. A town council for Leaside was elected on May 8, 1913 and they approved the plan for the town on May 21, 1913, which was the final legal approval needed before the plan could be implemented. On June 21, 1913 the Toronto World carried the announcement that properties in Leaside's planned community would be marked in the fall of that year. In September 1913 lots went on sale within the planned community.

In 1914 the industrial area that had been set aside east of Laird Drive received its first tenant. Canada Wire and Cable began construction of a factory for production of 9.2 inch shells for World War I. In addition to the new factory, Canada Wire and Cable moved their other Toronto production plants to the same location to increase efficiency. Canada Wire and Cable also created the subsidiary company Leaside Munitions Company to oversee shell production. Soon after construction began on a federal government owned airstrip, named Leaside Aerodrome. The York Land Company leased about 220 acres (0.9 km2) to the government for the airfield, between Wicksteed Avenue and Eglinton Avenue. On May 21, 1917 construction began on the airfield. At the close of the war, there were accommodations for around 1000 military personal.

While the industrial development in the area went ahead as planned during World War One, the anticipated residential development did not occur. As late as 1929 the population remained under 500. World War I spurred the demand for industrial output but diminished the call for new housing. The bankruptcy of Canadian Northern Railway left the project at a loss and Leaside's isolated location made it unappealing to workers from Toronto.


On January 1, 1967 Leaside was amalgamated with the township of East York to form the borough of East York. As such Leaside became a neighbourhood within East York. Passenger train service to Leaside Station ended in 1970, and the station was closed. The station would reopen briefly in the 1980s as a restaurant, but would see no further passenger traffic. Leaside Airport fell into disuse, and in 1971 the last hangar was demolished. Canada Wire and Cable was purchased by Alcatel in 1991, and the operations relocated to Markham in 1996, with the location being converted to a shopping centre. The plant had expanded through the years and been a major influence in Leaside, employing over 2700 workers at its peak. It had also been a strong influence over the community in other ways, investing in the community in various ways, including the construction of a water main in 1918. East York merged with five other municipalities and a regional government in 1998 to form the new City of Toronto.



Demographically, the Leaside community is made up predominantly of single-family homes housing upper-middle-class families. The most famous house in Leaside is James Lea's, located at 201 Sutherland Drive. Built in 1909, it is unique in that the back of the house faces Sutherland Drive. It was originally built to face a street that no longer exists. The 22nd and current Prime Minister Stephen Harper was also born in Leaside. Due to city expansion, Leaside has become prime real estate with the GTA, and has attracted many local celebrities, such as NHL goaltender Trevor Kidd, Avalanche winger Darcy Tucker, Ex-NHL player Doug Gilmour, and comedian Colin Mochrie and his actress wife Deb McGrath.


The largest recreation centre in Leaside is Leaside Memorial Community Gardens which includes an indoor swimming pool, an ice rink, a curling rink and a large auditorium. It also was where Peter Mahovlich Sr. father of the famous NHL brothers worked after coming to Toronto in the 50s from the Timmins area because of Franks impressive hockey skills as a youth in the Porcupine. Serena Gundy Park is located in the north-east corner of Leaside. The parkland was donated to Leaside in 1960 by the estate of James H. Gundy. The park covers 62.6 acres (253,000 m2) which are generally in a natural state. The park is used for picnicking and hiking in the summer and cross country skiing in the winter. Trace Manes Park is located in south Leaside. The park is home to the Leaside Tennis club and sports six tennis courts. Other facilities in the park include a playground, a baseball diamond and an outdoor ice rink in winter. Howard Talbot park in south-west Leaside features two baseball diamonds. Additionally it features a "splash pad", a water playground for young children.


Northlea Elementary and Middle School is located on the site of the old Divadale Estate on Rumsey Road north of Eglinton Avenue. It was opened in 1944 and had 15 classrooms. In 1991-93 the school underwent extensive renovations and the school now educates over 800 students. The renovation provided additional classroom space to the school as well as a new library and a second gymnasium. The school is operated by the Toronto District School Board. Northlea is a dual track school offering regular English programs from Junior Kindergarten to Grade 8, and French Immersion programs from Senior Kindergarten to Grade 8.

Bessborough Elementary and Middle School, located on the same road as the high school: Leaside High School in South Leaside has offered a great deal of education to those living in the older part of Leaside. St. Anselm Catholic School, also located on Bessborough Drive, opened in 1939 and presently has an enrollment of 340 students from Junior Kindergarten to Grade 8. Leaside High School began on the top floor of Rolph Rd. School in 1945. The "new" high school opened in September 1948 and welcomed back local students who had been attending Lawrence Park and Jarvis Collegiate. Rolph Road Elementary School, an elementary school for junior kindergarten to grade 6, is the other elementary school in the neighbourhood. Located on Rolph Road, it is in South Leaside and is a feeder school to Bessborough.
