Retirees may, without paying tuition fees, attend courses as special students or for credit, subject to the usual academic requirements (including requirements regarding admission to programs). Retirees may also audit courses, subject to availability of space.
Unless you already have a student number, you will need to set up a profile using https://uoforms.uottawa.ca/specialstudent. The Office of the Registrar will then create your special student profile within a few days.
Once registered in your course(s), you may ask for your tuition fee exemption at https://web47.uottawa.ca/tuition-waiver/index.php.
