Yes, it’s possible to do so.
If you’re an undergraduate student:
The University of Ottawa has agreements with Carleton University and Saint Paul University allowing students to take courses at these institutions without having to pay additional tuition fees. However, if the course you want to take at one of these institutions is also offered at uOttawa during the same term, your request will generally not be approved. An exception can however be made if the course is full, if the course is absolutely required to complete your program, or
for other valid reasons. Other rules may also apply; please contact your Faculty for more information.
If you wish to take a course at a university for which no such agreement is in place, you must obtain a letter of permission from your Faculty by filling out the appropriate form. If your request is approved, you will receive a letter of permission that allows you to register for a course at the other institution (this institution could also ask for other documents). You will have to pay administrative fees to the University of Ottawa, as well as tuition fees to the other institution.
If you're a graduate student:
If the university is in Ontario, first check whether it is part of the Ontario Visiting Graduate Students (OVGS) Program. If so, please complete and submit the student application form found on the OVGS website.
If the institution is not part of the OVGS program or is outside Ontario, you must obtain a letter of permission from your Faculty by filling out the appropriate form. If your request is approved, you will receive a letter of permission that allows you to register for a course at the other institution (this institution could also ask for other documents). You will have to pay administrative fees to the University of Ottawa, as well as tuition fees to the other institution.
