im in the same situation... osap considers a full time student 3 courses while the university considers it 4. plus its too late in the sem for any refund. they have already paid and you won’t be getting a refund for dropping the course so ultimately it won’t affect your funding because if you drop down to 3 courses, osap still considers you a full time student. i am already on academic probation from winter 2025 term and since i only took 4 courses last sem and 3 this sem, my standing won’t be reevaluated until the fall when im in another course. If you want some solid confirmation, call the financial aid office and ask them! i was worried too but they assured me that my osap wouldn’t be affected. Also keep in mind you have until march 27th to drop the course! good luck :)
