In Canadian English, the term college usually refers to a technical, applied arts, or applied science school. These are post-secondary institutions granting certificates, diplomas, associate's degree, and bachelor's degrees.
In English Canada, the term "college" is usually used to refer to technical schools that offer specialized professional or vocational education in specific employment fields. They include colleges of applied arts and technology, colleges of applied sciences, etc.
In Ontario and Alberta, and formerly in British Columbia, there are also institutions which are designated university colleges, as they only grant under-graduate degrees. This is to differentiate between universities, which have both under-graduate and graduate programs and those that do not. There is a distinction between "college" and "university" in Canada. In conversation, one specifically would say either "They are going to university" (i.e., studying for a three- or four-year degree at a university) or "They are going to college" (suggesting a technical or career college).
