exists to this day. After the suburb of Brockton was annexed in the 1880s, the final section of College Street was built to Lansdowne Avenue in 1886. It was expected that College would be extended further, but just west of Lansdowne the rail lines created a barrier. A precursor to an extended College Street, called Grenadier Road, was laid out in the Roncesvalles district, and on the west side of High Park in Swansea (now Morningside) as well as a section in Etobicoke (now Berry Road), but connections to those streets were never made. Streetcar service extended as far west as Dufferin by 1889, and (via Dundas Street) to High Park by 1893. Sunday operation of the line to High Park did not begin until 1897, after a citywide plebiscite was held on the issue of Sunday streetcar operation. The streetcar led to the development of residential sub-divisions on both sides, with street frontages actually empty. The frontages were used for billboards, with development on the street only filling up the lots on both sides by World War I, although some vacant lots existed into the 1920s. Route description The intersection at Yonge Street is dominated by the landmark College Park complex, which once housed an Eaton's department store. This historic building is now used for retail, office, and residential purposes. At University Avenue, College traverses a major institutional district, with the Ontario Legislature, the University of Toronto, and the MaRS Discovery District marking one of the city's most important and historic intersections. The district also features a concentration of teaching hospitals, including Toronto General Hospital, the Hospital for Sick Children, Princess Margaret Cancer Centre, Mount Sinai Hospital, and Toronto Rehab. Between University and Spadina Avenue, the street bounds the Grange Park neighbourhood to the south, a mixed-residential area with student housing and historic residences such as George Brown House. The intersection at Spadina Avenue represents the northern boundary of the city's principal Chinatown, as well as the western boundary of the university. The intersection is marked by the focal point of 1 Spadina Crescent in a roundabout to the north, and a complex rail interchange where the busy 510 Spadina streetcar route, running on a dedicated right-of-way, meets the 506 Carlton route. The section of College west of Spadina is home to a variety of computer stores, known as a destination for cheap computer parts. This stretch of College
