Results of a Canada-wide and a Quebec based study of students with a variety of disabilities in Canadian postsecondary education are presented. Study 1 involved 156 professionals. They represent 80% of the population of professionals who provide on-campus disability support services. Results indicate that (1) 8% of postsecondary institutions reported not having any students with disabilities, (2) overall, 2% of students are registered to receive disability related services from their postsecondary institutions, and (3) this varies from 1/2% to 6% across the country. Junior/community colleges had a higher percentage of students with disabilities registered to receive disability related services (3 3/4%) than universities (1 2/3%). (4) Distance education had 3%. (5) Quebec has a smaller proportion of both college (2/3% vs 6%) and university (1/2% vs 2 1/2%) students with disabilities than the rest of Canada. A targeted study involving 46 professionals who provide disability related services in Quebec's public junior/community colleges, the CEGEPs, revealed that lack of recognition of learning disabilities for postsecondary funding by the Quebec government is an important contributor to the small percentages, although it cannot explain the huge discrepancies between Quebec and the rest of Canada. Extrapolation suggests that there are over 100,000 students with disabilities currently enrolled in Canadian postsecondary education, although only 1/4 to 1/2 of them register to receive disability related services.
