What kinds of people are most likely to be refused visas when studying in Canada?

The visa refusal rate of Canadian students is indeed higher than that of other countries. People who are easily refused visas are:

People of marriageable age who have interrupted their study experience, are unmarried or divorced in China, and have unstable income;

People whose majors are sensitive or popular to immigrants and whose study plans are unreasonable;

The overall assets and income of the family are problematic and irrational;

Family income is not enough to cover people who need to study abroad.

Generally speaking, the reasons given by visa officers are mainly immigration tendency and lack of funds, which are reflected in insufficient domestic constraints, dissatisfaction with your travel history, dissatisfaction with your travel purpose, doubt that you will not return to China after studying abroad, and dissatisfaction with your economic situation. So you can consider whether you have avoided these minefields before submitting your visa.
