Night school, summer school, online courses: do Ontario universities care?

Updated August 22, 2026

Most accept them as equal, provided the school is inspected by the Ministry of Education. A handful say they may ask why — and one group enforces a hard cut-off date for when the mark arrives. The difference between those three positions is the whole answer, and which universities sit where is below.

The rumour, and where it comes from

Every year someone on Reddit says night school is “patched” — that universities have started rejecting marks earned outside the regular day timetable. The rumour survives because it is a quarter true. Three universities say, in the counsellor guide, that they reserve the right to ask why a course was taken outside day school and what mark it replaced. That is not a rejection policy. It is a flag. But it is enough to keep the story alive.

The rest — the large majority — say the opposite in plain language: a credit is a credit, provided the school that issued it is inspected by the Ministry of Education. The full breakdown:

The Ministry-inspected condition

Almost every answer carries one condition: the school must be a Ministry of Education inspected school. Public boards are. Most well-known online providers are. A private credit mill that promises a 95 may not be — and if it is not, the credit may not be recognised for an OSSD at all, let alone by a university. Before paying for a private-school course, find the school on the Ministry’s list of inspected private schools. If it is not there, the mark will not help you anywhere.

The date problem nobody mentions

A second group of universities does not care where you took the course. They care when the mark arrives. Universities receive grades from the OUAC on fixed dates — the first full set in late February, the spring set in early May, finals in July. A summer school mark that lands in August is too late for a decision that was made in May. If you are taking a prerequisite in summer school after Grade 12, check the program’s conditional-offer wording: some will hold a place, some will not.

Night school or summer school to repeat a course is a different question, and it has a different answer at every university — some use the higher mark, some the most recent, some average the attempts. Which mark each university uses if you repeat.

What the three “may ask questions” universities are really saying

Read their wording below. What they describe is a pattern: a student who drops a course in day school with a 62, retakes it at night school, and returns with a 91. The university sees both attempts on the transcript — the OUAC sends every attempt — and reserves the right to ask which one represents you. Taking a course at night school because it did not fit your timetable, or because you are taking seven courses, is not that pattern and does not draw the question.

What to actually do with this

If you are choosing between a day-school course and the same course online or at night because of timetable, take it wherever it fits — at a Ministry-inspected school — and stop worrying. If you are planning to replace a weak day-school mark with a night-school retake, look up your target universities below and on the repeated-courses page before you spend the money, because at a few of them the first attempt still counts.
