What it is	You study the design, development, and theory behind computer software and systems. In the co-op stream, you alternate between classroom terms and paid work terms at tech companies, giving you practical experience alongside your degree. This program suits people who want to build real-world coding skills early and explore whether they prefer software development, artificial intelligence, games, or other computing specializations while earning money.	Engineering at Western teaches you to design and build solutions to practical problems using mathematics, science, and materials. You choose a specialization like software, mechanical, civil, or chemical engineering, or study general engineering first before deciding. The program includes co-op work terms, so you alternate between classes and paid jobs with employers, giving you real experience alongside your degree.	This program teaches you to design and build complex systems — often combining software, hardware, human behaviour, and business — that solve real-world problems. Unlike a traditional engineering program focused on one discipline, it blends computer science, design thinking, and management so you learn how systems work across multiple fields. It suits students who want engineering skills but prefer understanding how all the pieces fit together and spending time working in industry during their degree.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
