Short answer: in Canada there is no reliable distinction between a thesis and a dissertation. Canadian universities apply both words to master’s and doctoral work, sometimes interchangeably in the same document. The distinction that carries real consequences is a different one: research-based versus course-based, because that determines funding eligibility and doctoral admission.
Search for this question and you will be told, confidently, that a thesis is what you write for a master’s degree and a dissertation is what you write for a doctorate. That is a description of American usage. It is repeated so often that Canadian students arrive at their own graduate office expecting it to be true, and then find their university’s forms saying something else.
Why does Canadian usage vary?
Because nothing standardises it. Degree requirements in Canada are set by each institution, generally through a school or faculty of graduate studies, and the vocabulary follows local tradition rather than a national rule. There is no Canadian equivalent of a central registry that fixes the meaning of these words.
The result is visible on the universities’ own pages. McGill’s Graduate and Postdoctoral Studies runs a Thesis Office and asks doctoral candidates directly whether they are “writing, or on the verge of writing, your PhD thesis” — doctoral work, called a thesis. The University of British Columbia’s graduate school files the same stage under Dissertation & Thesis Preparation, carrying both words together. The University of Toronto’s School of Graduate Studies, in a single FAQ about editing, refers to “the graduate thesis” and to refining writing “for their dissertation” within a few sentences of each other.
None of these is wrong. They are three institutions using an unstandardised vocabulary, which is exactly why you should take the term from your own program’s regulations and stop trying to infer it from general guidance.
What does each term usually mean here?
| Term | Typical Canadian use | Reliability of the label |
|---|---|---|
| Thesis | An extended, supervised, examined research document at either master’s or doctoral level | Common at both levels; the default word at several institutions for doctoral work |
| Dissertation | The same object, more often but not exclusively doctoral | Used alongside “thesis” at many universities, including for the same document |
| Major research paper (MRP) | A shorter supervised research document in a course-based master’s, in place of a thesis | Reasonably consistent; length and defence rules vary widely |
| Mémoire | At francophone Quebec universities, the master’s research document | Consistent within the francophone system, where thèse is doctoral |
The last row is worth pausing on, because it is the one place in Canada where the distinction is genuinely stable. In the francophone Quebec system, mémoire de maîtrise and thèse de doctorat map cleanly onto the two levels. A student moving between the anglophone and francophone systems is crossing a real terminological boundary, not an imagined one.

What is a major research paper?
An MRP is a supervised piece of original research, shorter than a thesis, that many Canadian course-based master’s programs require in its place. It is a real research requirement — you pose a question, review a literature, gather or analyse evidence, and defend your reasoning in writing — but it typically carries a lower credit weight, a shorter length, a single supervisor rather than a full committee, and in most programs no oral defence.
Students sometimes treat the MRP as a lesser document and write it accordingly. That is a mistake with a downstream cost, because for anyone considering doctoral study the MRP is often the only sustained piece of independent research in the file.
Which distinction actually has consequences?
Not thesis versus dissertation. The one that changes outcomes is research-based versus course-based, and there is an objective national definition of it — attached to money.
The federal graduate scholarship rules define an eligible program of study as one that is “predominantly research oriented, leading to the completion of a thesis, major research project, dissertation, scholarly publication, performance, recital and/or exhibit that is merit/expert-reviewed at the institutional level as a requirement for completing the program.” The same rules state that master’s programs “based only on course work are typically not eligible since they do not include a significant research component.”
Three things follow that are worth knowing before you choose a program:
- A major research project counts. The definition names it explicitly alongside the thesis and the dissertation. A course-based master’s with a genuine MRP is not automatically excluded — a master’s with only coursework is.
- Non-textual outputs count. A performance, recital or exhibit satisfies the definition, provided it is merit or expert reviewed institutionally. Students in music, fine arts and design often assume federal funding is closed to them; the wording says otherwise.
- Professional and clinical programs are not excluded by type. Joint degrees such as MD/PhD, JD/MA or MBA/PhD, and clinically oriented programs including clinical psychology, are eligible where they have a significant autonomous research component.
If your program falls on the research side of that line, you will need data to put in it. A large share of Canadian quantitative thesis work runs on national statistical files, and the access tiers are less obvious than they look — our guide to getting Statistics Canada microdata for your thesis sets out which tier requires what.
How do the requirements differ in practice?
Regardless of the label, a thesis-track Canadian graduate degree tends to move through a recognisable sequence: a supervisor and supervisory committee, an approved proposal, ethics clearance where human participants are involved, chapter drafts reviewed by the committee, an initial submission, an oral examination, corrections, and a final deposit.
The staging is real and institutionally distinct. McGill separates initial thesis submission from final thesis submission with the oral defence in between, and recruits faculty as Pro-Deans to chair those defences. UBC runs a Final Doctoral Exam as a defined step before final submission. Those are two different administrative architectures for the same milestone, and the deadlines attach to the steps rather than to the document.
An MRP track usually compresses this: supervisor, draft, revision, submission. Fewer gates, less committee scheduling, and a shorter runway — which is why course-based master’s programs are often completed in twelve to sixteen months while thesis-based ones run longer.
Does the label change what examiners expect?
Less than the level does. What an examiner asks of a doctoral document — an original contribution, command of the field, methodological defensibility — is set by the degree, not by whether the cover page says thesis or dissertation. What changes with the label is administrative: submission portal, formatting specification, deadline calendar, and the rules on what help you are allowed to have.
That last point is worth stating precisely, because it is where students get into trouble. The University of Toronto’s School of Graduate Studies permits the use of an external copy editor only with a strong rationale and the prior approval of the supervisor and supervisory committee, requires that “the intellectual content of the thesis cannot be modified through the external editing process,” and requires the student to “clearly identify the contributions of an external copy editor to their work in the thesis document.” Students may even be asked to supply before-and-after copies. That is one university’s rule, not a national one — but the principle behind it, that the intellectual content must be yours and any assistance must be disclosed, is close to universal in Canada.
How should I decide between the two tracks?
- Start from where you want to be in three years. If a doctorate is plausible, a thesis or a substantial MRP gives you the supervised research record that doctoral admission committees read.
- Check funding eligibility against the actual wording, not the program’s marketing page. “Predominantly research oriented” with a merit-reviewed research output is the test.
- Ask what the examination looks like. An oral defence is a different skill from a written submission, and knowing which one is coming shapes two years of preparation.
- Read your own regulations for the word. Whatever your program calls the document is what your forms, deadlines and formatting rules will call it.
Once the track is settled, the document itself is the work. Start structuring your thesis or MRP in Tesify — chapter scaffolding and citation handling stay consistent while every argument remains 100% written by you.
Frequently asked questions
Is a Canadian master’s thesis longer than an MRP?
Almost always, but there is no national figure. Length is set programme by programme, and the same nominal word count can mean different amounts of writing depending on whether appendices, footnotes and references are included.
Can I switch from a course-based to a thesis-based master’s?
Many Canadian programs allow a transfer in the first year, subject to finding a supervisor and to space in the research stream. Because it affects funding eligibility, ask the graduate coordinator rather than assuming it is a formality.
Do I defend a major research paper?
Usually not. Most MRP programs assess the written document, sometimes with a presentation. A minority require an oral examination, so confirm against your own regulations.
Does an MRP make me eligible for federal graduate funding?
It can. The eligibility wording names a “major research project” alongside the thesis and dissertation, provided the programme is predominantly research oriented and the output is merit or expert reviewed institutionally.
Is a doctoral document called a thesis or a dissertation in Canada?
Both are used. Several major Canadian universities call doctoral work a thesis; others use dissertation, and some use both. Follow your own institution’s term.
What is the difference between a mémoire and a thèse?
In the francophone Quebec system a mémoire is the master’s research document and a thèse is the doctoral one. That mapping is consistent, unlike the anglophone Canadian usage.
Does a thesis need research ethics approval?
If it involves human participants or human biological materials, yes. The requirement attaches to what you do to participants, not to the type of document — see our guide to REB approval and TCPS 2.
Are performance or studio outputs accepted as research?
For federal funding purposes yes, where a performance, recital or exhibit is merit or expert reviewed at the institutional level as a requirement for completing the programme.
Can I use an editor on my thesis?
Only under your institution’s rules, which typically require prior approval, prohibit any change to intellectual content, and require disclosure of the editor’s contribution in the document itself.
Does the label affect how my degree is recognised abroad?
Recognition is based on the level and the awarding institution, not the word on the title page. A Canadian doctoral thesis and a doctoral dissertation are the same qualification.
Which track finishes faster?
Course-based and MRP programs generally finish sooner because they have fewer scheduled gates — no committee formation, no oral defence to calendar, and a shorter research phase. The trade-off is a thinner research record.
