There is a non-refundable fee of $95.00 CDN to apply to college through ontariocolleges.ca.
The application fee includes up to 5 program choices (no more than 3 at any one college); the programs must start within the same academic year (August to July). To apply to programs starting in the next academic year, you will need to create a new application and pay a new application processing fee.
Your application will not be forwarded to your college choices until the application processing fee has been received. Payment of this fee doesn't guarantee that you will get an offer to your program of choice, but you can make changes to your program choices within the same application cycle without any additional payments. Please note that there are no exemptions from the application processing fee.
Other fees may apply in addition to the $95.00 application processing fee, including transcript request fees for some educational institutions.
