Questions

What is the difference between co-op and internship?
In Canada a co-op is a paid work term that is part of a school program (usually 4, 8 or 12 months); internship is the word many employers, especially US ones, use for the same kind of student job. YesJob shows both together.
When should I apply for a co-op term?
Usually 3 to 6 months before it starts: Winter terms (January to April) are hired in the fall, Summer terms (May to August) in winter and early spring, Fall terms (September to December) in late spring and summer.
Do I need to be enrolled in a co-op program?
Many postings require current enrolment in a post-secondary program and some require a school co-op program. Read the requirements on the employer's page.
Can international students apply?
International students usually need a co-op work permit for a required co-op term. Postings that say citizens or permanent residents only are tagged; most postings do not say.
