Computer Science


Computer science is concerned in the broadest sense with the study of computation and applications of computing. Its development has been stimulated by collaborations with many areas including engineering, the physical and life sciences, mathematics and statistics, and commerce.

Course offerings in the Computer Science program are intended to serve a wide variety of students, ranging from those whose primary interest is in information processing to those interested in applying computing to other fields.


Entry to the Computer Science, Mathematics & Statistics admission category is gained directly from high school. Applicants who have completed any postsecondary studies (including studies at other divisions at the University of Toronto) are not eligible for admission.


The 2020-21 Academic Calendar contains the requirements for entry into all CS programs. The CS minor is open to any student. The CS major and specialist, information security specialist, and bioinformatics specialist are all restricted enrollment programs that require minimum marks in particular courses (CSC148H5 and MAT102H5) and a minimum CGPA.

Previously, we guaranteed that the requirements in 2021 would not exceed 80 percent in CSC148H5, 80 percent in MAT102H5, and a 3.3 CGPA.

At this time, we are pleased to announce that for the May 2021 enrolment round, the minimum requirements are 80 percent in CSC148H5, 73 percent in MAT102H5, and a CGPA of 3.0.

We do not include CR/NCR grades when calculating CGPA.

Note that only CSC148H5 and MAT102H5, taken at the UTM campus, will be accepted for the purposes of program enrolment.

(Note: We will refuse students that have a pending Academic Offense Case. If you meet the entry requirements once the case is resolved and any penalties have been applied, please contact us.)

The requirements for the August 2021 POSt enrolment round will be announced in early September.

Many students who intended to apply to the August 2020 enrolment round were unable to do so due to a deferred 148 exam or the cancellation of the summer CSC148 offering. To mitigate these issues, we will evaluate students admitted to the university in Fall 2019 and applying for enrolment in a CSC POSt in May 2021 or August 2021 using the criteria from the May/August 2020 enrolment round.


Here are common alternate majors to consider that pair well with a CS major or minor:

* Applied Statistics
* Communication, Culture Information, and Technology
* Economics
* Geographical Information Systems (GIS)
* Mathematics
* Professional Writing and Communication

If you do not meet the requirements for entry to a CS program in your first year, the department strongly recommends that you plan as if you will graduate with a CS minor. The programs above would pair well with CS and can be completed in three years, meaning that you will stay on schedule to graduate. 


All CS majors and specialists contain a half-credit writing requirement. The recommended course to satisfy this requirement is ISP100H5. Students can also satisfy the writing requirement with any of CSC290H5, CCT110H5, ENG100H5, HSC200H5, HSC300H5, LIN204H5, WRI203H5, WRI173H5.

If a student wishes to substitute another course to satisfy the writing requirement, the student should draft a formal letter naming the replacement course and describing how it meets the desired outcome of familiarity with technical and professional modes of communication. Submit this letter to the Faculty Advisor. If your petition is approved, then the course you propose will be accepted in lieu of ISP100H5 when you are assessed for graduation.


Students not enrolled in a computer science major or specialist program are restricted to completing a maximum of three third or fourth year computer science courses. Every term, the department removes students from courses who exceed this limit to give all students a fair chance to enroll in upper year courses.

We typically remove non-program students by the beginning of the second week of the academic term. After the removals are complete, all students are permitted to enroll in as many CS courses as they would like, as long as there is space in the course. We believe this strikes a fair balance between (a) providing access to courses for students in the specialist and major, (b) providing access to courses for students in the minor who have not yet completed three upper year courses, and (c) providing access to extra courses for students in the minor.
