If you are under the age of 19 at the start of a program, you must have an Ontario Secondary School Diploma (OSSD) or equivalent. Applicants who are 19 years of age or older do not need ot have an OSSD. If you are 19 or older and do not have an OSSD, you may apply as a mature student.
You will be tested and interviewed to see if you meet the program prerequisites.
NOTE: International students applying from outside Canada must have the equivalent of an OSSD and cannot apply as mature students.
