William Lyon Mackenzie Collegiate Institute

William Lyon Mackenzie Collegiate Institute (W.L. Mackenzie C.I.; locally known as Mackenzie) is a semestered high school located in Toronto, Canada. The school was opened in 1960 by the North York Board of Education. It is located near Sheppard Avenue West and Allen Road, close to Sheppard West subway station. History The school, originally called Southview Heights Secondary School, was built in 1959. The purpose of the school was twofold: to accommodate the skyrocketing number of new students in the area, and to ease overcrowding at Northview Heights Secondary School. The school opened in September 1960. It was originally slated to be a junior high school. A contest for the school's name was held and William Lyon Mackenzie, the first mayor of Toronto and leader of the Upper Canada Rebellion in 1837, was selected. The school, in its inception, had 90% of the Jewish student population that lived in the Bathurst Manor neighborhood.
