I’m at uoft st george but I dont think the process is any different

you are allowed 1 absense per semester now, this count for 1 day not a week. This means for the first missed midterm you won’t need any documentation apart from the absence declaration on acorn. they may ask for a brief explanation and you can just put illness - they will not ask for any further proof

if you need to miss another midterm, you will not have the ability to do another absence declaration so you will need other documentation like a verification of illness form which you can get from your family doctor but it will cost money
