The neighbourhood of Sunnylea is located on the south side of Bloor Street West. It begins at the intersection of Bloor Street West and Prince Edward Drive and extends further south, past the cemetery and then east to the Humber River to Berry Road. It then extends west to Islington Avenue south to Norseman Street.

Sunnylea is a highly sought after neighbourhood that is especially popular with young families. There is a country charm here thanks to the Mimico Creek which gently meanders through the centre of this neighbourhood. Sunnylea's many mature trees and the exclusion of sidewalks add to its country-like ambience.

The homes reflect the English architecture of the Kingsway homes just north of Bloor Street. This neighbourhood’s proximity to subway transit and the many shops of the The Kingsway has attracted executive families, with many renovations and new builds taking place to reinvigorate this area. Sunnylea is also known for its excellent schools which are a popular drawing card for this neighbourhood.

The history of the Sunnylea neighbourhood revolves around Alexander Thompson who purchased two hundreds acres of land in this area in 1803, after his discharge from the Kings Rangers.

Alexander Thompson lived in a distinguished residence, just south of Bloor Street at Royal York Road that was known as "Rose Bank Cottage." His son Archibald lived in a country Georgian farmhouse just to the south of his father,that was called "Spring Bank Cottage." Spring Bank Cottage is still standing today at 7 Meadowcrest Road. The Thompson property was renowned for its apple, cherry, pear and plum orchards. In the latter part of the 1800's the Thompson's were joined in Sunnylea by families who cultivated thriving market gardens filled with fruits and vegetables. A handful of these old Sunnylea farmhouses are still standing both on Prince Edward Drive and on Islington Avenue.

In 1907, the first Sunnylea School, a two room white brick schoolhouse, was built on Prince Edward Drive. Sunnylea's old farms were subdivided in the 1930's and 40's, when the present day neighbourhood was developed. The influx of new families to this community led to the opening of the second Sunnylea school in 1942.
