What is the difference between a co-op and an internship in Canada?

In the Canadian education context, co-op and internship are often used interchangeably, but there are important technical and immigration differences:

Co-op (Cooperative Education):
- Structured alternating programme — typically work terms alternate with study terms
- Mandatory part of the academic programme
- Usually 4-, 8-, or 12-month paid work terms with employers
- Students get co-op work permit (separate from off-campus work limit)
- Often full-time during work terms
- Facilitated by the university's co-op office — helps match students with employers
- Programmes: Engineering, Computer Science, Business, and Science at many universities
- Examples: University of Waterloo (one of the world's largest co-op programmes), UBC, University of Ottawa

Internship:
- Usually a single work experience, not alternating
- Can be mandatory or optional
- If mandatory: Co-op work permit applies
- If optional: Counts against off-campus work limit (20 hrs/week during school)
- Can be paid or unpaid (unpaid internships are increasingly restricted in Canada)
- Typically 4 months (one semester)

Immigration significance:
The co-op work permit allows full-time work during placement terms and does not count against your off-campus 20-hour limit. Optional internships do not get this benefit.

Career outcomes: Co-op graduates consistently get more job offers at graduation and earn higher starting salaries. Many co-op employers convert students to full-time hires — this is particularly valuable for building the PGWP work experience needed for Express Entry.

If immigration is part of your plan, choosing a programme with mandatory co-op is a strong strategic move.
