Computer science is a great choice for those who are creative, like to solve puzzles, enjoy digging into complex problems, and are inspired by inventing solutions that can help people. Communication and teamwork skills are valuable assets for a computer scientist.

Now is a great time to study computer science; the job market is strong, and it is expected to be among the fastest growing industries in coming years.

Many computer science graduates work with both computers and people in the software industry.  Their focus may be on software architecture and design, programming, analysis of user requirements, or quality assurance. Some are entrepreneurs running software production or consulting firms.

Computer scientists also work in some highly specialized areas, such as computer graphics and animation, game programming, web application development, user-interface design, mathematical and scientific programming, financial modelling, and robotics.

Some computer scientists go on to graduate degrees and research careers in industrial or government laboratories, or academic careers at the university level.

Professional Experience Year (PEY)

The PEY program is a 12-16 month paid work term that offers you an opportunity to complete a substantial industrial project, and to see how academic work relates to the “real world.”

This program is available to full-time students and are completing the second or third year of their BSc degree.

Participants gain both experience and contacts, through working for such companies as AMD (Advanced Micro Devices, Inc.), IBM and Wattpad. The annual salary of our PEY students last year was between $47,000 and $68,000 per year.
