This school was named after Reginald Harold King (February 16, 1896 – November 4, 1962), a Canadian educator and classicist.

There was no provision in the High School Act, so legislation was put through the offices of George S. Henry, Member of Provincial Parliament.

The Board of Trustees purchased seven acres of land from the farms owned by the family of David Pherrill for $14,000 and on June 29, 1922, the cornerstone was erected for the new building.

After reviewing many qualified applicants, the Board chose Dr. Reginald Harold King for the position of principal.

The school building was still under construction but classes began on September 6, 1922, in the basement of Birch Cliff Congregational Church with Dr. King, three staff members and 116 students.

took pride in its history from the beginning, recording its events in an annual edition of the local newspaper "The Advertiser".

As another war began against Nazi Germany and Fascist Italy in Europe and Imperial Japan and Asia, a new call for soldiers went out and SCI.

had grown into a school with a strong tradition in sports such as Hockey, Basketball, Rugby, Student Clubs and some new problems - Double Shifts.

The Double Shifts were as follows: The same teachers taught the whole day, and to make matters more challenging, the power was turned off at 4 pm to save electricity.

Light for the remainder of the day came from two lanterns hanging in the middle of the class, with the teacher giving individual instruction.

SCI was still growing at an incredible rate because in 1954 the double shift programme was re-introduced temporarily until new facilities were complete.

"In area" students were granted the first available spaces, but could opt to go to one of the other nearby high schools if the "Academy" system was not what they wanted.

There were no specific "academic" requirements for admission to King, but students and their parents did need to agree to abide by the Academy's uniform and other policies.

[citation needed] These line-ups became a marketing problem for the board of education, so a more equitable system where students were selected through a lottery-system was established.
