UofT Academic Calendar 2026-2027: Important Dates and Deadlines

The UofT academic calendar 2026-2027 below includes enrolment dates, drop deadlines, exam periods, petition deadlines, and more.

The University of Toronto operates across multiple campuses (St. George, Mississauga (UTM), and Scarborough (UTSC)), and while the overarching academic structure is similar, specific sessional dates can vary slightly by faculty or campus.

The University of Toronto’s primary academic year (Fall/Winter session) generally comprises 24 weeks of instruction, delivered across two distinct 12-week semesters or terms: Fall (September to December) and Winter (January to April).

Additionally, the university offers a flexible Summer session, which typically includes two shorter terms for accelerated study.

This resource compiles all the UofT important dates. From application cut-offs and course registration periods to tuition payment deadlines and final examination schedules, stay organized and on track for a successful academic year at U of T’s St. George, Mississauga, or Scarborough campuses.
