It is a non-semestered composite high school and home of the Science, Technology, Engineering and Mathematics (STEM) Centre of Innovation program.

Before the construction of the new local high school, students who lived in the West Hill area attended Scarborough Collegiate Institute (renamed to R.H. King in 1954).

As its fourth high school in the borough, West Hill Collegiate Institute opened its doors on September 6 1955, with 25 staff and 376 students along with its first principal, Harvey A.C. Farrow and vice-principal Francis S. Jennings.

[3] From the 2009-10 school year, West Hill kept the Warriors moniker, but the Native American head, which was used since its inception, was replaced with a stylized Trojan mascot in 2010.

[5][6] The crest for West Hill consists of a red shield with a white shield bordered in black and silver containing a red sun on the top, between a magic lantern (commonly found on most school logos in the TDSB) and a sheaf is the school motto, "Surgo in Lucem" (I rise into the light) in a black banner.

On the bottom of the crest, there is the white banner inscription that reads "West Hill Collegiate Institute".

West Hill shares the same design as Winston Churchill Collegiate Institute and has since altered overtime.

It began with 27 rooms but the school underwent a renovation during the 1970s to create an additional 50 classrooms, four gymnasiums, a library (named after West Hill's first principal, H.A.C.

Farrow), two studios for the Drama Department, workshop rooms, and a quad to enable creative learning opportunities for studies in science.

Student philanthropists participate in an organization called Me to We which aims to make positive differences for society on a local and global level through events throughout the school year.

West Hill offers Advanced Placement opportunities in Mathematics, English, Chemistry, Biology and Physics which prepare students for studies at university.
