It is also where many world-class universities are located, including the University of Toronto, Queen's University, McMaster University, University of Waterloo, University of Western Ontario, York University, University of Ottawa, and Wilfrid Laurier University.

Ontario's education system and high school graduation requirements:

Ontario adopts a four-year high school system for grades 9-12. To attend university, students need to receive the Ontario High School Diploma, which requires the completion of 30 credits in high school (18 required course credits and 12 elective course credits; one credit is given per course), as well as at least 40 hours of volunteering.

In addition, students must pass the Ontario Secondary School Literacy Test (OSSLT) in order to attend university.

Quebec (QC) has a relatively special status in Canada, as its official language is French and it hosts the largest concentration of French-speaking population in North America. One of the best universities in Canada, McGill University, is located in Montreal, the largest city in Quebec.

Quebec's education system and high school graduation requirements:

The education system in Quebec is slightly different from the previous three provinces. There are 6 years of elementary school, 5 years of secondary school (3 years of junior high school and 2 years of senior high school), 2 years of pre-university or 3 years of vocational specialization, and finally university education.

Quebec's 5 year secondary education leads to either a Diploma of Secondary Studies (DES) or a Diploma of Vocational Studies (DEP). High school students must complete a minimum of 54 credits in the fourth and fifth years of high school to receive the DES, and 20 of these 54 credits must be from fifth year courses.

High school graduates are first enrolled in the General and Professional Teaching College (CEGEP), where they can choose between a two-year pre-university program that prepares them for university education, or a three-year technology education program, which allows them to work as technicians and craftspeople.
