It seems like the competition is quite demanding. I called UofT and they put me on the wait-list for MPH health promotion because of my "lack of research experience". I've worked for the national department of health as a researcher, had a public health internship overseas, and worked for Statistics Canada in data analysis, published 2 papers with my professor in the health science department where I was named one of the authors, and have gone to Africa 3 times for rural housing outreach projects. 3.9 GPA. Not really sure what they are looking for.....
