Recommendation Form


Documents Required

The application procedure has two components: (1) an electronic form (including the payment of a $100 application fee by credit card) and (2) a set of additional documents to be sent to us by mail. We will not begin to consider your application until ALL the materials have been received. We are not always able to send you a letter indicating whether your application is complete or not; therefore, it is your responsibility for ensuring that your referees respond. Please encourage them to do so promptly.

University On-Line Application

Please complete the online application, including the credit card payment of the $100 application fee. 


Please refer to the University's Application Procedures for questions related to the electronic admission procedure.

Note the following areas that must be completed:
  • "Degree or Diploma for which you are applying", enter M.Sc. or Ph.D
  • "University Year to which you are applying" select Year 1; only Ph.D. applicants who hold a M.Sc. degree should select Year 2
  • "When do you wish to start", you should NOT choose "Summer"
  • "Country of Citizenship" is also very important, if not Canadian, please indicate your citizenship.

Documents to be sent by mail

1) General Information Form M-1 (download pdf file)

2) Computer Science Background Form M-2 (download pdf file)

All applicants must complete this form. This information will be used to determine whether you satisfy the minimum requirements. Please be as specific as possible.

3) Two Completed Recommendation Forms M-3 (download pdf file)

We greatly prefer receiving academic references, that is, letters supplied by university professors or course instructors. If you had a supervisor for your university studies or for a thesis, we would like one of the letters to be supplied by this person (this is especially important for Ph.D. applicants). If you graduated from university several years ago, we realize that it may be difficult to obtain academic references. In this case, you may substitute letters from your employers or co-workers. (We give academic references much more weight when assessing an application). Letters of reference must be no more than six months old. You should ask each referee to give you the letter in a sealed envelope and sign the envelope across the seal. You may then submit these sealed references together with your application. This may eliminate some delays in evaluating your application. If you or your referee prefer, reference letters can be mailed directly to us by the referees.

4) Official GRE Test Score (where applicable)

If applicable, please fill in the result of your GRE test on Form M-1. Note that the official copy must be supplied by the Educational Testing Service directly to the School. All international applicants must submit their GRE scores.

5) Official TOEFL Test Score (where applicable)

If applicable, please fill in the result of your TOEFL test on Form M-1. Note that the official copy must be supplied by the Educational Testing Service directly to the School. Canadian students (whether from English of French-speaking universities) and international students who did their undergraduate degree in an English-speaking university do not need to submit TOEFL scores. If you claim exemption from the TOEFL because you have attended a university where English is used, please tell us of this. Perhaps you can ask to have this fact mentioned in one of your reference letters. For French speaking foreign applicants, we will accept other evidence of proficiency in English (e.g. acceptable grades in English courses taken at a university).

6) Two Copies of Official University Transcripts

We require two official copies of transcripts covering your entire university career. An official transcript must be issued by your University and mailed directly to us, or it can be sent with your application, but it must be sealed in an envelope by your University. Please include proof of degrees granted where applicable. If you submit a photocopy of your transcripts you will not be permitted to register until official transcripts are received. We do not require certificates, etc., from high school or other institutions attended before university. It is often difficult to evaluate transcripts when the grading scheme used differs from those commonly used in North America. If this applies in your case, please make sure a description of the grading scheme is included. Failure to do so may cause your application to be rejected.

7) Other Information

Do not hesitate to include information you think will support your application. Ph.D. applicants MUST provide a statement outlining the objective of their graduate program, i.e., preferred areas of study, potential research interests and proposed supervisors. For the Ph.D. program, the School requires a list of at least 3 proposed supervisors that you would like to work with in order to process your application.

Deadline for September Admission

ALL documents for both M.Sc. and Ph.D. applications must be submitted by March 1. If you wish to be considered for financial assistance, ALL documents for admission must be submitted by January 1st. You are encouraged to apply early, this allows time for correspondence should there be any problems with your application.

Applications for January Admission

In general, we do NOT accept applications for January admission. This is because most Winter courses have Fall courses as pre-requisites. On occasion, a student graduating in December with a very strong background in Computer Science may be accepted for January admission. International applicants must submit ALL documents by August 1st, Canadian applicants by September 1st.

Application Decisions

M.Sc. and Ph.D. applications for September admission are reviewed in February and March. Applicants are informed of decisions shortly thereafter.

The School does always have the resources to respond to individual inquiries concerning results of an application. You will be notified, in writing, of our decision. Later, you will receive notification, in writing, from the McGill Faculty of Graduate and Postdoctoral Studies of the official admission decision. The School only has the power to recommend admission decisions to the Faculty. It is possible (but unusual) for them to alter our recommendation. Once we write to you informing you of a recommendation, you must understand it is always subject to final, official approval by the Faculty.

Deferred Admissions and New Applications

Students admitted to a program may request to defer their admission to the same program for a period of up to one year, without having to pay a new application fee. This does not apply to special or visiting students, who must apply and pay an application fee every year. The application for deferral must be made in writing, signed by the student, to the academic unit offering the student's program. The signed request must state the desired term of deferred admissions and the reasons for requesting a deferral, the current mailing address, telephone and email address.

Approval of the deferral is not automatic. The academic unit, or the GPSO, may reject a request, subject to the program's enrolment limitations in the new term, the sequence and availability of required courses, the reasons for requesting a deferral. In addition, if the first acceptance was conditional, non-completion of conditions of admission or poor academic performance since the initial admission are valid reasons to refuse a deferred admission.


Important: A student must NOT complete the online application for admission to request a deferral, since submitting an online application requires a credit card payment of the application fee.
  • a signed letter from the student requesting the deferral, indicating the requested term and stating the reasons;
  • the student's current mailing address, telephone number and email address;
  • a new decision form from the department, clearly marked "DEFERRAL";
  • any supporting documents for any conditions of acceptance cleared or for any further studies completed since the initial acceptance;
  • optional: a new application form, if provided by the student, clearly marked "DEFERRAL"
