Can You Defer an Exam in Ontario?
Yes. Every Ontario university and college has a formal academic accommodation process for students who miss exams due to illness. Ontario is unique because many universities have moved to self-declaration systems for short absences (typically under 3 days), but final exams and weighted assessments almost always still require medical documentation from a licensed physician.
This guide covers the exact process at every major Ontario university, including which schools accept self-declaration and which require a doctor's note.
University of Toronto (U of T) Exam Deferral Process
U of T uses the Absence Declaration Tool for short-term absences but requires medical documentation for final exam deferrals.
Steps to Defer at U of T:
1. Declare your absence through ACORN's Absence Declaration tool within 72 hours
2. Petition your college registrar for a deferred exam (St. George) or submit through your campus registrar (UTM/UTSC)
3. Provide supporting documentation — medical note from a physician
4. Attend the deferred exam during the next exam period
What U of T Requires:
- For short absences (under 3 days): Self-declaration via ACORN may suffice for midterms
- For final exams: Medical documentation from a licensed physician (CPSO-registered)
- The U of T Verification of Illness form is no longer mandatory — a standard medical note is accepted
- Must confirm you were unable to write on the specific exam date

What Makes a Valid Sick Note for Ontario Exam Deferrals?
Ontario universities require documentation from a CPSO-registered physician (College of Physicians and Surgeons of Ontario). Here's what every valid note must include:
| Required Element | Details |
|-----------------|---------|
| Date of consultation | Must be on or before the exam date |
| Statement of incapacity | Confirms inability to write the exam |
| Duration of illness | Shows exam date falls within illness period |
| Physician's full name | For verification purposes |
| CPSO registration number | Proves Ontario licensure |
| Physician's signature | Legal requirement |
| Clinic information | Address and phone for verification |
Ontario Privacy Note:
Under Ontario's Personal Health Information Protection Act (PHIPA), your physician is NOT required to disclose your diagnosis to your university. Your note only needs to confirm that you were medically unable to attend — not why.
Self-Declaration vs. Medical Note: Ontario's Evolving System
Since 2023, many Ontario universities have adopted self-declaration for minor absences:
| University | Self-Declaration Available? | For Final Exams? |
|-----------|---------------------------|-----------------|
| U of T | Yes (ACORN tool) | No — need medical note |
| Western | Yes (coursework <10%) | No — need SMC |
| McMaster | Yes (MSAF, work <25%) | No — need medical note |
| Queen's | Limited | No — need medical note |
| York | Varies by faculty | No — need APS |
| uOttawa | Yes (some coursework) | No — need medical note |
The bottom line: Self-declaration works for small assignments and short absences, but final exams and major assessments still require a doctor's note at every Ontario university.
The Problem: Getting a Sick Note in Ontario During Exam Season
Ontario's healthcare access crisis hits students hardest during exam season:
- 1.8 million Ontarians don't have a family doctor (2026 data)
- Walk-in clinic waits: 3-6 hours during December/April exam periods
- Campus health centres: Fully booked 1-2 weeks in advance during finals
- After-hours options: Limited, especially outside Toronto
The Timing Problem:
If you wake up sick on exam day, you need a medical consultation that same day for most Ontario universities to accept your deferral. By the time you get a walk-in appointment, the deadline may have passed.

Frequently Asked Questions
Can I use the MSAF/self-declaration for a final exam at McMaster?
No. The MSAF only covers assessments worth less than 25% of your grade. Final exams always require medical documentation submitted through your Associate Dean's office.
Does U of T still use the Verification of Illness form?
No. U of T eliminated the mandatory VOI form in 2023. They now accept any medical note from a licensed physician that confirms you were unable to write on the exam date. However, you still need to petition through your college registrar.
What if I'm sick but my exam is tomorrow and I can't get an appointment?
This is exactly why MedLetter exists. Same-day virtual consultations mean you can get documentation on the day you're sick, even if it's 10 PM the night before your exam. Most Ontario universities require the consultation date to be on or before the exam date.
Can my professor refuse my deferral if I have a valid sick note?
For final exams, individual professors typically don't make the decision — it goes through the registrar or faculty office. For midterms, professors have more discretion, but a valid CPSO-registered physician's note is very difficult to refuse.
How many exams can I defer in one term?
There's no official limit, but deferring multiple exams in one term may trigger a meeting with your academic advisor to discuss whether you should consider a late withdrawal instead.
What if I have a chronic condition that flares up during exams?
Register with your university's accessibility services office for ongoing accommodations. For acute flare-ups during exams, you'll still need documentation for each specific instance, but your accessibility registration strengthens your case.
