In all cases, admission is based almost entirely on academic marks gained in high school, generally grade 12, although some schools also consider grade 11 marks as well. In most cases, an overall average of at least 70% in high school will suffice.

Each college and program has its own admission requirements. An Ontario Secondary School Diploma (OSSD) or equivalent is usually required. In order to be admitted to a graduate certificate program, you must have a degree, diploma, or certificate from a college or university.  College admission requirements vary more significantly than university requirements. University requirements are fairly straightforward.
