Program details
Overview
Computer Science at Western University is an undergraduate Bachelor of Science program in the Faculty of Science, structured around modules rather than a single fixed curriculum: students can pursue an Honours Specialization, Specialization, Major, or Minor in Computer Science, with separate minor options in Game Development and Software Engineering. A five-year combined-degree route pairs an Honours Specialization in Computer Science with Ivey's HBA for students who want both a technical and a business credential. First-year coursework covers programming fundamentals, information systems, and multimedia communication, while upper-year courses branch into areas such as software systems, artificial intelligence, cryptography, visual analytics, and game design. Students can apply to the Science Co-op Program from second year for paid work placements. Beyond coursework, the program supports experiential options including community-engaged software projects, open-source contribution, a Summer of Code stream, game development projects, study-abroad terms, and thesis-based research for students who want an independent research component. Teaching is delivered on Western's main campus in London, Ontario. The module system and elective breadth suit students who want to specialize within computing while keeping the option to combine study with co-op or business training.
Requirements
Admission Requirements: Western's Computer Science admission page lists four required Grade 12 U courses for Ontario applicants: English (ENG4U), Advanced Functions (MHF4U) and Calculus and Vectors (MCV4U), plus one further course from Mathematics of Data Management, Biology, Chemistry, Physics, Earth and Space Science, or Computer and Information Science. Western publishes a mid-year admission-average guideline of low-to-mid 80s for Ontario applicants, noting that falling in the suggested range does not guarantee a seat given competitive demand. The page states no program-specific English-proficiency score; applicants whose first language is not English must instead meet Western's institution-wide policy: IELTS Academic 6.5 overall with no band below 6.0, TOEFL iBT 83 with no section below 20 (before January 21, 2026, otherwise 4.5 overall on the new scale), PTE Academic 58 with no section below 56, or Cambridge C1 Advanced/C2 Proficiency 176 with no section below 169, unless exempt.
Application Details
Application Deadline:Western applies through the Ontario Universities' Application Centre, which opens for Fall 2027 entry in late September 2026; Western's own equal-consideration deadline for full-time undergraduate study is 15 January 2027, the same date used for domestic (OUAC 101/105) and international applicants alike, since Western publishes no separate international closing date. Several named programmes carry their own earlier deadlines within the cycle: Medicine (MD) closes 1 October 2026, Law (JD) and Dentistry (DDS) close 1 November 2026, Education (BEd) closes 2 November 2026, and Western Integrated Science closes in early April 2027. Students already enrolled in an Ontario high school cannot be required to respond to an offer before 1 June 2027. Admission is not rolling: applicants are assessed against these published deadlines. These are institution-wide dates; this programme publishes no deadline of its own.
