What it is	Computer Science at Western teaches you how to write programs, build software systems, and solve problems using computers and code. You choose a focus — such as game development, managing information systems, or engineering robust software — based on your interests. The program includes paid work terms alongside your studies, letting you apply classroom learning in real jobs and build professional experience before you graduate.	You study the theory and practice of building software, designing systems, and solving problems with computers. Carleton's program lets you focus on specializations like artificial intelligence, games, or software engineering, and includes a co-op stream where you alternate between classroom and paid work terms. This suits students who want hands-on industry experience alongside their degree and are interested in both the technical and applied sides of computing.	You study business fundamentals — accounting, finance, marketing, management, and human resources — while earning a degree from both University of Ottawa and a partner institution abroad. The dual degree means you spend time at two universities and graduate with credentials from both, giving you international experience and exposure to different business practices. This suits students who want a business foundation with global perspective and the opportunity to study and work in another country.	A Bachelor of Commerce is a four-year business degree where you study accounting, finance, marketing, human resources, and management. McMaster's program includes a mandatory co-op work term, so you alternate between classroom learning and paid work experience at real companies. This program suits people who want broad business knowledge and practical work experience before entering the job market.
