McMaster supplementary applications

Dates we checked ourselves

Engineering, Computer Science, iBioMed and Bachelor of Technology

A Kira Talent supplementary application — not CASPer. Four questions: three video responses (1 minute to prepare, 2 to answer) and one written response (10 minutes). There is a 0 fee paid through OUAC. You only complete it once even if you apply to several Faculty of Engineering programs; the invitation arrives from Kira within 10 business days of applying.

Honours Health Sciences (BHSc)

A mandatory supplementary application. Every row of McMaster’s timeline has been reset to "Coming Soon" for this cycle — questions, portal access and offer dates alike. Their warning is worth reading twice: "Supplementary Applications portal access is time limited. Extensions are not granted."

Arts & Science (OUAC code MX)

A mandatory two-part form. Part A is five questions with a 1,500 character limit each; Part B is an equity/facilitated-admissions section every applicant must complete. Needs a MacID, which arrives about a week after your OUAC application. McMaster states plainly that using generative AI to help write it "will be considered an infringement of academic integrity".
