Do you have a study permit to enter Canada? That is step 1.
Even if you do, or even if you have already studied in Canada, you must comply with the requirements for entering Canada at the time of travel. Some students, for example, who were already students in Canada, must now get a renewed medical clearance if the medical clearance used for their study permit has expired.

Each of these categories has its own checklist of requirements.

We always emphasize it is necessary to check continuously. It is even possible the rules change in the last day before your departure. Many of our students are requiring supporting documents from the institution and it is important to leave enough time to request and receive these documents. Comments to blog@cuac.ca
