In the Canadian university lingo, co-op refers to a (usually paid) internship that you complete as part of your degree. You usually have a couple co-op terms/semesters along with your traditional terms. For example, you may start your degree with two semesters of classes, then a semester of co-op, then one of classes, then another two co-ops, more classes, etc. until you complete the degree requirements. Degrees with a co-op requirement usually will make mention of it (e.g. Software Engineering with co-op).
