What should I do if I am warned that the attendance rate of studying in Canada is low?

The project was warned by the school, and the result was not too bad. There's still a chance to fix it. Communicate with the school in time the reasons for their low attendance. As long as it is reasonable, the school will cancel the warning. However, if you can't find a suitable reason, the school will truthfully report the fact that the student's attendance rate is low to the Immigration Bureau, and finally cancel your status as an international student.

On April 20 15, Immigration Canada took the lead in launching the DLI portal system. On April 20 16, the Ministry of Immigration began to require certified educational institutions to use the system to register student information. The DLI portal will report the collected information to the Canadian Immigration Bureau. International students who miss too many classes will be repatriated directly.

I hope the answer will help you.
