A stream is a series of area-specific courses that you take as part of your degree. It allows you to specialize in a particular field of study. If you intend to apply for a job within a particular field corresponding to one of our streams, then the stream will allow you to be more prepared/trained for that field of work. Some streams begin in first year, allowing you to take a stream-specific course during each year of the program. Other streams have course-specific requirements that only begin in third year.
