In York's info session they said last year they got 300 applicants for 20 spots in their two year program, and 250-300 applicants for 40 spots in their advanced standing program.
Laurier was 400 applicants for 78 spots in their two year program and 200 applicants for 28 spots in advanced.
Lakehead's MSW takes 10-12 people per campus per year.
I believe Ryerson has about 40 spots in their program, not sure how many applications they get.
