If you apply for a university in Canada, you must have a domestic high school diploma. If not, you must first take a high school course in Canada and get a Canadian high school diploma. Students apply directly to public universities in Canada based on the credits and language scores of six preparatory courses (12U) in grade 12 in Canada; Students with poor English level must take ESL courses first.

If the graduates of previous technical secondary schools have work experience related to their professional background, they can apply for Canadian community college diploma courses that meet their own conditions.

Students who are studying in high schools and technical secondary schools (no high school diploma, no test report card and no language scores) can go to Canada to study in the tenth, eleventh and twelfth grades of middle schools, that is, high school diploma courses. Diane International College in Toronto offers the Ontario High School Diploma Program (OSSD). With an Ontario high school diploma, you can apply to any university in Canada.

It's impossible without a diploma, but as I wrote above, you can take high school courses first, and you don't need to go to a technical school. I suggest you apply for a foreign high school with your junior high school report card. If you take a technical school diploma, you can only go to a community college, not a junior college.
