Complete these steps before you reach out to a faculty member!

Check requirements
  • Familiarize yourself with program requirements. You want to learn as much as possible from the information available to you before you reach out to a faculty member. Be sure to visit the graduate degree program listing and program-specific websites.
  • Check whether the program requires you to seek commitment from a supervisor prior to submitting an application. For some programs this is an essential step while others match successful applicants with faculty members within the first year of study. This is either indicated in the program profile under "Admission Information & Requirements" - "Prepare Application" - "Supervision" or on the program website.
Focus your search
  • Identify specific faculty members who are conducting research in your specific area of interest.
  • Establish that your research interests align with the faculty member’s research interests.
    • Read up on the faculty members in the program and the research being conducted in the department.
    • Familiarize yourself with their work, read their recent publications and past theses/dissertations that they supervised. Be certain that their research is indeed what you are hoping to study.
Make a good impression
  • Compose an error-free and grammatically correct email addressed to your specifically targeted faculty member, and remember to use their correct titles.
    • Do not send non-specific, mass emails to everyone in the department hoping for a match.
    • Address the faculty members by name. Your contact should be genuine rather than generic.
  • Include 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. The supervision enquiry form guides you with targeted questions. Ensure to craft compelling answers to these questions.
  • Highlight your achievements and why you are a top student. Faculty members receive dozens of requests from prospective students and you may have less than 30 seconds to pique someone’s interest.
  • Demonstrate that you are familiar with their research:
    • Convey the specific ways you are a good fit for the program.
    • Convey the specific ways the program/lab/faculty member is a good fit for the research you are interested in/already conducting.
  • Be enthusiastic, but don’t overdo it.
Attend an information session

G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.

Determinants of health, mental health disorders and health satisfaction in Canada (2020)

Introduction: Mood and anxiety disorders are the most prevalent mental health disorders worldwide; they can cause significant physical distress and impaired functioning. In Canada, quantifying and describing the impact of these disorders is a priority. Objectives: (1) To explore the trends in the prevalence of mood and/or anxiety disorders by geographical regions in Canada, and to assess key determinants of health associated with mental health disparities across these regions. (2) To assess whether food security, access to regular medical doctor, and sense of belonging to the community mediate the relationship between mood and/or anxiety disorders and general health satisfaction.Methods: This serial cross-sectional study used data from a nationally representative sample of Canadians, aged 18-59, from the Canadian Community Health Survey, annual cycles 2011-2016. Bivariate relationships were examined using chi-square tests for categorical variables and t-tests for continuous variables. Adjusted logistic regression models were used to identify which factors were associated with the prevalence of mood and/or anxiety disorders (using SAS 9.4). Mediation models were based on the Sobel product of coefficients approach (using Stata version 13).Results: The prevalence of mood and/or anxiety disorders increased across all regions between 2011 and 2016, with Quebec consistently having the lowest prevalence, and the Atlantic region having the highest. In most regions, individuals who drank occasionally or regularly, males, immigrants, non-Caucasians and those with a strong sense of belonging to a community were less likely to be diagnosed with a mood and/or anxiety disorder. Across most regions, sexual orientation and food security were the characteristics associated with our outcome. In our second analysis, for most years, respondents who described having fair/poor general health satisfaction reported a weak sense of belonging to the community, being food insecure, and having a mood and/or anxiety disorder. In our mediation analysis, food security and sense of community belonging partially mediated the association between mood and/or anxiety diagnosis and general health satisfaction. Conclusions: This research provided new data for provincial governments to identify programs and policies that intervene to improve key health determinants associated with mood and/or anxiety disorders across regions in Canada.
