You have two options. You can either purchase a one-time 3 month study pass extension for $45 CAD through your personal online account on campus OR you can purchase a campus membership for a year for a discounted price of $120. Once you have lost access to campus, the study pass extension option is no longer avaiable, but you may purchase the annual campus membership for $150 through the campus login page.
Alternatively, you could register for a new course before your current study pass expires, which would ensure continued access to the courses you currently have access to. We simply add on time to your existing study pass (four months for most courses, or eight months for Intensives).
