The honest version of the answer
Search for this question and you will find two unhelpful answers: that the OSSD is easy, and that it is a shortcut around harder systems. Both are marketing, and both mislead the students who act on them.
Here is a more useful framing. The OSSD is demanding in a particular way, and undemanding in another way — and whether it suits a student depends on which of those matches how they work.
What the assessment model actually does
An Ontario course is marked out of 100, with 50 as the passing mark. The final mark is built from two parts:
- Coursework — assignments, unit work, quizzes, projects, presentations, participation — which forms the substantial majority of the grade
- A final evaluation — an examination, a culminating task, or a combination, worth the remaining portion
In CNA's own materials, this is described as a roughly 70/30 structure: about 70 per cent of the grade from work completed through the term, about 30 per cent from the final assessment. Some courses use a final project rather than an exam, and some include both.
What that structure changes is when a mark is decided. A course that is assessed mostly through term work is less dependent on a single morning than a system built on one high-stakes examination. A student who has a bad day in June has already earned most of the mark.
What it does not change is how much work is required. Four assignments assessed across a term are still four assignments.
Where students actually lose marks
In practice, difficulty in Ontario courses rarely comes from content that is too advanced. It comes from five habits, in roughly this order of frequency.
1. Leaving work until it accumulates. Asynchronous study means no one chases you. A two-week gap in a course where each unit builds on the last costs more time than it saves. This is the single most common cause of a disappointing result.
2. Reading a mark and ignoring the feedback. Teacher comments describe what to change. Students who apply one specific change to the next task improve quickly; students who look only at the percentage plateau.
3. Confusing familiarity with mastery. Students repeating a course often assume prior exposure is enough. It helps them study efficiently, but all required learning and assessment must still be completed.
4. Misreading the task. In subjects like English and the social sciences, a response that answers a different question than the one asked loses marks regardless of quality. Reading the rubric before writing is not optional.
5. Not asking. Contacting the course teacher with a specific question — this step, this concept, this comment — is the strongest predictor of a good outcome. Students who wait until the end of a unit to ask usually find the confusion has compounded.
Where the OSSD is genuinely more forgiving
Three structural features reduce pressure in ways that are worth understanding rather than dismissing:
- Multiple assessment points. A mark built from term work means no single task determines the outcome.
- Flexible pacing. Students can choose a weekly rhythm that fits their lives, and can re-watch recorded teaching rather than relying on one hearing of an explanation.
- Pathway breadth. A student can repeat a course, add a prerequisite late, or change direction without leaving the system. The 30-credit structure with a large optional component leaves room to adjust.
None of that makes the work smaller. It makes the timing of the work more controllable.
Where it is genuinely harder
Two honest cautions.
Independence is required. In an asynchronous course, no one notices on Tuesday that you have stopped working. Students who need external structure to start work — a fixed period, a teacher in the room — find online study harder than classroom study, even when the content is identical. CNA says this in its own materials: online learning offers flexibility, with less everyday face-to-face interaction than a conventional campus. That is a real difference, not a marketing footnote.
Mathematics and science remain cumulative. No assessment model makes MCV4U follow from anything other than MHF4U. In those subjects, the difficulty is real and the sequence is unforgiving.
A student scenario
Adam (pseudonym), Grade 11, Toronto — deciding whether online would work.
Adam had a mixed record: strong marks in subjects where he liked the teacher, weaker marks where he did not. His parents were considering an online Ontario course for a prerequisite he could not fit into his timetable, and they worried that the flexibility would become a problem.
Rather than committing to a full plan, they tested it. Adam took one online credit in a subject he found straightforward. The first month went badly — he completed almost nothing — and the reason was specific: he had no regular study window, so work happened "later".
Guidance helped him rebuild the plan around two fixed weekday evenings and one weekend block, with a weekly check on what he had actually finished. The second month was different. He finished the course with a solid mark, and the same routine carried into two more credits the following year.
The lesson his family drew was not that online study is easy or hard, but that it rewards a structure the student builds rather than one the timetable imposes.
He applied to university with all required prerequisites complete and received an offer from the University of Toronto.

How to judge whether it fits you
Answer these five questions honestly.
- Can you name two or three specific times each week when you will study?
- When something is unclear, will you email your teacher, or wait and hope it resolves?
- Do you read feedback, or only the mark?
- Do you have a target date, and have you planned backwards from it?
- Is there anyone at home or at school who will notice if a week passes with no progress?
Four or five yes answers is a good sign. One or two is a signal to build the missing supports before enrolling, not after.
Next step
If you are unsure, take one course rather than a full plan. Send your transcript and goals to Guidance and ask which course would be the most honest test of fit.
