Silverthorn Collegiate Institute

School History

Silverthorn Collegiate Institute is located in the neighbourhood of Markland Wood in the former suburb of Etobicoke. We are under the sanction of the Toronto District School Board (the successor to the former Etobicoke Board of Education). The name comes from the Silverthorn Woods that borders to the south and the west. This was the northern limit of an old property known locally as the Silverthorn Mill Farm. 

 When the Markland Wood's area was developed in the early 1960s, the Etobicoke Board of Education (the forerunner of the TDSB) decided to build a secondary school for the area. The school was to be named Silverthorn Collegiate Institute after the family who had first settled the area. The cornerstone was laid in 1963, and the school opened in September 1964 with a teaching staff of 24 and a support staff of 7. The building was designed by Dunlop, Wardell, Matsui & Aitken Architects. Murray Young was the first principal. The school had only grades 9, 10, and 11 in 1964. In the next two years, it added grades 12 and 13. In 1968-69 the school was doubled in size, with the addition of an auditorium, the library, science labs and technical and business areas. A second gym was added later on.

SCI is a semestered school. Days run from 9:00 am to 3:15 pm. Our school colours are garnet, green, and silver and our mascot is a Spartan. Our school's motto is "Nil Veretur Veritas" which is Latin for "The Truth Fears Nothing".
