CORS Diploma is mandated by http://www.cors.ca. As the Faculty Liaison for the CORS Diploma, I screen diploma requests and selectively recommend them to CORS organization if a student have taken the required courses as listed in CORS course requirements.
In general, students don't need to let me know ahead of time nor need my permission to take these courses. But for the required OMIS/MGTS courses, students do need to register them by filling in this OMIS Course Registration Form, and send it to the email address indicated within the form.
After you have taken all required courses, you may send your request, along with your transcript in a PDF file, to my email.
