Can a domestic undergraduate get a master's degree in Canada in three years? If I can apply, what are the steps?

Yes, you need undergraduate transcripts, self-introduction and letters of recommendation from two guarantors. Just like famous American universities, excellent TOEFL or IELTS scores are almost a prerequisite for applying to Canadian universities. For most universities, it is basically impossible to get the admission notice if they do not meet the English scores required by the school. In addition, in addition to TOEFL (now iBT) or IELTS, Canadian universities generally require applicants to provide GRE (science and engineering) or GMAT (business), but this requirement varies with schools and majors. In many schools, although the admission requirements say "Recommend GRE scores", students without GRE may be admitted, but applicants with GRE have a greater competitive advantage and will be admitted first.

Generally, Canadian universities require applicants to have a total score of at least iBT80- 100 (TOEFL written test) and a written test score of at least 20 points; The average IELTS score must be 6.5-7.0, and the listening, speaking, reading and writing scores must not be lower than 6.0. The GRE is above 1200, and the writing score is not less than 4.5-5. For management master applicants, the GMAT score should be no less than 550-600. For top universities or top majors in Canada, applicants' test scores may also be broken down, considering whether they are finally admitted or not.
