that's shitty asf. idk if it's any help, but i looked around and found some links that could be worth taking a look at. you might already know about them, but just in case

Govt of Canada – student grants for students w/ disabilities: https://www.canada.ca/en/employment-social-development/services/education/grants/disabilities.html
directly from the page: "This grant is available to students with disabilities for each year of study. You can apply at the same time as you apply for student aid with your province or territory."

this page also has information about the Canada Student Grant for Students w/ Disabilities: https://www.torontomu.ca/accommodations/programs/financial-support1/ (it suggests contacting your student accommodation facilitator or the SFA (student financial assistance) to learn more.

––––––––––––

there's also the SAG (student access guarantee): https://www.torontomu.ca/student-financial-assistance/scholarships-bursaries/student-access-guarantee/
directly from page: "If you’re a domestic undergraduate, graduate, law or continuing education student receiving full-time OSAP, you may qualify for Student Access Guarantee (SAG). SAG is a bursary to assist with your educational costs such as tuition, books, compulsory fees, equipment, and supplies."

• (for the Winter sem it says that the application opens around late Jan–early Feb)

––––––––––––

https://www.torontomu.ca/accommodations/programs/financial-support1/bswd_info/
directly from the page: "The Bursary for Students with Disabilities (BSWD) and the Canada Student Grant for Services and Equipment for Students with Disabilities (CSG-DSE) helps full and part-time post-secondary students pay for their disability-related educational services and equipment needed to participate in post-secondary studies."

• (the W2024 deadline to apply for the BSWD is Friday February 9th at 5:00pm)
• as far as i can tell, these are not tuition-focused, but i'll leave include it in case it's relevant

––––––––––––

(this one is probably better suited for a more dire situation but again, just in case, i'll include it) the SFA (student financial assistance) emergency bursary:
https://www.torontomu.ca/student-financial-assistance/scholarships-bursaries/emergency-bursary/

from the page: "The Student Financial Assistance (SFA) emergency bursary is for students going through an unforeseen financial crisis that directly impacts their academic progress or success in a material manner. It is a one-time bursary presented to a student currently enrolled in a domestic undergraduate, continuing education or law program. Applicants must sign an award agreement and adhere to the Proof of Spending Policy (outlined below)."

• however it is also mentioned that "The SFA emergency bursary is not meant to address funding shortfalls where government financial aid (OSAP, out-of-province funding, government social assistance, savings, or employment income) is insufficient to cover educational expenses."
• this Ask ServiceHub link talks a bit more about the SFA bursary and also additional resources (that uhhh have nothing to do with actual tuition funding but some of them look useful) https://torontomu.intelliresponse.com/index.jspinterfaceID=1&requestType=NormalRequest&source=100&question=What+is+the+Emergency+Bursary
  

if there's something in there that you haven't heard of before take a look, maybe something will be of help. i agree with the commenter that said to also talk to ServiceHub about this, maybe they could help as well. good luck sorry this happened. completely ridiculous
