- Computer Science (BSc)last cycle's date
A written supplementary response: list achievements or experiences not reflected in your transcript that show your interest and potential in computing. It opens on the Join U of T applicant site after you submit through OUAC. Note this is worded differently from the St. George Computer Science supplement — applying to both campuses means completing two.
The deadline is February 16, 2026.
