Emailing a Supervisor for a Master's in Canada
How to email a potential supervisor for a thesis master's in Canada: what McGill, UBC and uOttawa say to include, how many to contact, when to follow up.
Emailing a Supervisor for a Master's in Canada
Send one short email per professor, written for that professor, and only where the email can change something: a thesis master's (MASc, MSc, thesis MA) where a supervisor decides admission or you need to know who is taking students. For a course-based MEng or MScAC, do not email for admission. Plan for one follow-up, then decide by early December.
Our own guide to contacting a PhD supervisor, and the templates in it, are written for US, UK and European PhDs. A Canadian thesis master's is a different case. In several departments the professor's yes is the admission decision and the funding decision at once, and the application deadline falls in December or January. So the email is not a courtesy. It is the first step of the application, and it should be built backwards from your program's rule and its deadline.
Every university page quoted below was checked on October 31, 2026. Deadlines are for September 2027 entry unless the page states no year, which we flag.

First check whether the email is required, optional or pointless
Canadian programs use one of three supervisor models, and the full table is in do you need a supervisor to apply in Canada. In short:
- Required in practice (Model A). No supervisor, no offer. UofT Mechanical & Industrial Engineering (MIE) MASc, McGill Anthropology, McGill Physiology, Queen's Psychology and McMaster Neuroscience work this way. The email is how you get a supervisor.
- Optional (Model B). A committee admits; you name faculty on the form or in the statement. An email can tell you who is active and taking students, but it does not decide the file.
- Pointless for admission (Model C and course-based). The program assigns an advisor after arrival, or the degree has no thesis. UofT MIE's MEng asks for a letter of intent and a CV, and nothing in its application instructions asks you to contact faculty.
If your program is Model B or C, the rest of this page is optional reading; for a course-based letter, the Canadian statement of intent guide explains how the MEng and MASc letters differ. If it is Model A, keep going.
What Canadian departments say the email must contain
Three of the Canadian university pages we checked publish instructions for this email, and they agree with each other on the basics.
| Source | Put in | Leave out |
|---|---|---|
| McGill Graduate and Postdoctoral Studies | "Dear Professor/Dr. (lastname)"; the program you are applying to; CV and unofficial transcripts; "specific published articles by the professor"; funding you already hold | Generic text: messages must be "tailored to each professor, not generic" |
| UBC Graduate and Postdoctoral Studies | "a brief outline of your academic background, why you are interested in working with the faculty member, and what experience you could bring to the department" | "Do not send non-specific, mass emails to everyone in the department hoping for a match." |
| uOttawa Faculty of Health Sciences | "Introduce yourself."; "State your interests clearly and how they match those of the professor."; "Include information on your academic background and research experience." | "Don't send generic emails." |
Two more lines change how you write. McGill says: "If you already have funding, state the amount, duration and source." If you hold a scholarship from home, it goes in the first paragraph, not the last. uOttawa reminds you why a strong email can still get a no: "professors are not obligated to take on a student if they feel the match would not be appropriate or if they lack lab space, time or funding."
McGill Computer Science adds a step before you write: "Please check the webpages of professors carefully before sending any emails. Several professors get many requests and might have specific guidelines regarding being contacted by potential students." If a professor's page asks applicants not to email about admission, that instruction overrides every template, including ours.
Constructed example: a 120-word email for a MASc
Constructed example, written by us, not a real applicant's email. Context (invented): a final-year B.Tech student in India applying to an environmental or mechanical engineering MASc. The professor, paper and numbers are placeholders.
Subject: Prospective MASc applicant, September 2027: humidity error in low-cost particulate sensors
Dear Professor [Surname],
I am a final-year B.Tech student in mechanical engineering at [University], and I plan to apply to the MASc in [Department] for September 2027.
Your group's [year] paper on calibrating low-cost particulate sensors reported that error grew with humidity. In my final-year project I ran 12 sensors next to a reference monitor for six months and saw the same effect. A linear correction removed most of it, but not above 80% relative humidity. I would like to work on that remaining error in a MASc thesis.
Are you considering new MASc students for September 2027? My CV and transcript are attached as PDFs.
Thank you for your time.
[Full name] [University], B.Tech Mechanical Engineering, expected May 2027
What each part does:
- The subject line names the degree, the intake and the topic. A professor can sort it without opening it.
- Paragraph one states who you are and what you are applying to, which McGill asks for in its "State why you are writing" line.
- Paragraph two is the whole case: one result from their work, one thing you built, one open problem you would work on. This is what McGill means by referring to "specific published articles by the professor".
- The question can be answered in one line. "Are you taking students?" gets replies. "Can you review my profile?" does not.
- What is missing on purpose: no praise of the university's ranking, no list of every course, no request for funding in the first email.
Our arithmetic: the email from "Dear" to "Thank you for your time." is 111 words; the two signature lines bring it to 120, and the subject line adds 11 more.
The research-interest paragraph: specific enough to answer
The paragraph that carries the email is also the core of your letter of intent, so write it once and well.
Two constructed examples, written by us, not real applicant statements:
Weak: "I am passionate about environmental engineering and sustainability. Your research is very impressive and matches my interests perfectly."
Revised: "I want to understand why low-cost particulate sensors drift in humid air, and whether a correction built in one city transfers to another. I have six months of co-located readings from my final-year project and a linear correction that fails above 80% relative humidity."
The weak version could be sent to any professor in any department, which is exactly what UBC and uOttawa tell you not to do. The revised version names a problem, the data you already hold and where your current method stops. A professor can answer it with "yes, that is my next grant" or "no, we have moved on", and either answer is useful.
When you move this paragraph into the letter, check what the program asks for around it. UofT MIE's MASc letter asks you to describe "your research interest, career goals, the courses you intend to take" in 650 to 1,000 words; UofT statement of intent limits by department lists the other UofT rules.
How many professors, and in what order
None of the Canadian pages we checked sets a number. UBC sets the only firm rule: no mass emails.
Our recommendation: start with three to five professors whose current work, judged by their last two or three years of papers or funded projects, matches your paragraph. Write each email separately. Never CC two professors on one message. Wait about ten working days before you add a second round.
The basis: in Model A programs, each professor is a separate admission route, so you need more than one. UBC rules out the mass email, and McGill CS warns that in machine learning "many have limited capacity to take on new students".
The countercase: if the program publishes who is available, start there and the list may be shorter. Queen's Psychology posts a Faculty Available to Supervise 2027-2028 page with a column showing "faculty availability to take in international students for Fall 2027". If only two names on that list fit your work, email two.
Order matters less than fit. If a lab page names a contact for prospective students, write to that person first.
No reply: a follow-up calendar built on Canadian deadlines
Our recommendation: one follow-up, about ten working days after the first email, as a reply in the same thread, adding one new fact (your application is submitted, a test score arrived, a short draft of your research question is ready). After that, silence is an answer. For PhD outreach the same logic is set out in following up when a professor does not reply.
For the dates around this email, including when referees can start, see the Fall 2027 Canadian master's checklist.
What you do next depends on the program's model and deadline:
| Program | Published deadline | Model | Decision point (our recommendation) |
|---|---|---|---|
| Queen's Psychology | "December 1st of each year", application and reference letters | A | Mid-November: widen the list |
| UofT Computer Science, MSc | December 1, 2026 | B | Submit; do not wait for replies |
| UofT ECE, MASc | January 7, 2027 | B | Submit; name compatible faculty |
| UofT MIE, MASc | January 1, 2027 fee; January 15 documents | A | Early December: submit, keep contacting during review |
| McMaster Neuroscience | January 14, 2027 | A | Mid-December: widen the list |
| McGill Physiology, international | January 15; supervisor confirmation by March 1 (no year stated) | A | Submit by January 15; confirmation can follow |
Two rules from those pages shape the calendar. Queen's Psychology warns that "referees will only be able to submit reference letters after the application is submitted, please make sure to submit your application at least a few days prior to the application deadline." And UofT MIE says MASc applicants may contact professors "either before or after submitting an application", so a Model A program does not always require a yes before you submit.
The decision in early December is simple. In a Model B or C program, submit, whatever your inbox says. In a Model A program that accepts confirmation after submission (UofT MIE, McGill Physiology), submit and keep writing to new professors. In a Model A program that wants a supervisor before you apply, such as the Queen's Cultural Studies PhD, either widen the list now or move the application to next cycle.
Follow-up after you have applied
Once the file is in, one short note is enough: the program, your application or applicant number, the date you submitted and one sentence on your research question. Do not reattach everything.
If the professor replies with a call invitation, the MASc supervisor interview guide covers what you will be asked and the funding questions to ask.
Where a program says faculty search the files, this note matters less. McGill CS says that for the MSc thesis, "interested professors will contact you when seeing your application." UofT MIE says that once a file is under review, "Faculty members will review applications and may contact students about offering supervision." For questions to the graduate office rather than a professor, see emailing grad admissions after you apply.
If a professor replies yes, the next step is to turn that yes into what the program counts, covered in what to do when a Canadian supervisor says yes.
Questions about emailing supervisors in Canada
Should I email the graduate coordinator first?
McGill says to: "Prior to researching and speaking to potential supervisors, make sure to contact the academic unit offering your program in order to establish a relationship." The coordinator can tell you whether the department expects contact at all, which saves emails in a Model B or C program.
Should I attach my statement of intent?
Not in the first email. McGill lists the CV and unofficial transcripts as the attachments. Send the statement only if the professor asks for it.
Is a professor's reply asking for my CV a yes?
No. It is a screening step. Send what was asked within two working days and wait for an explicit answer about supervision. Once a psychology supervisor replies, the psychology master's statement of intent in Canada shows how to write the two-year plan they will read.
For French-language universities, see writing to a directeur de recherche, with a constructed email in French.
Applying to a US master's instead? See emailing a US professor for an RA after admission.
