The Ontario Secondary School Diploma is a diploma granted to secondary School graduates in the Canadian province of Ontario. It is part of the publicly-funded province-wide school system. It is awarded to all students who complete the Ontario education curriculum.
The main advantage of obtaining OSSD is that it can be recognized by the best universities in Ontario and other parts of Canada to obtain the best university education. Most secondary education institutions need an effective and complete OSSD teaching plan to consider applying it to their curriculum.

Through years of education experience of OSSD, the Great Oaks Secondary School inspires students to improve their lives and expand their horizons. The students can develop their academic potential, build self-confidence, develop global perspectives and multicultural communication skills so that they can go further in the future.
