If you want to study in Canada you may need a Study Permit. If you plan to study either with a educational course or a complete program such as a degree or diploma you can apply for a study permit. Depending on the duration your studies take, your work permit length will vary.
Studies are lasting up to six months: If you want to study for only a few months or a short period of time (studying up to six months), you do not need to apply for a student visa. The courses could be related to any topic, full or part-time but can not be leading towards a certificate, diploma or degree. An extension of this permission is not authorized to complete this same course. During this time you are not permitted to work. For this, you only require an Electronic Travel Authorization (eTA) or Temporary Resident Visa (TRV).
Studies are lasting more than six months: This study permit is usually valid for the duration of the program and grants an additional 90 days after graduation to apply for a Post Graduate Work Permit or provide time to prepare to return to your home country. If you cannot conclude your studies before the duration of your study permit, you need to request the extension of the validity of your study permit. If you finish your studies before the estimated time, the 90 days will start running regardless of the date on your study permit. The study permit is not a visa; you may need an Electronic Travel Authorization (eTA) or a Temporary Resident Visa (TVR) to enter Canada depending on your country of nationality.
The general requirements for the study permit are;
Full-time post-secondary student studying in a program that will lead to a certificate, diploma or degree (college, university or CEGRP in Quebec)
Valid study permit
Have a Social Insurance Number (SIN)
You cannot continue working after your study permit expires or when you are no longer a full-time student.
You are allowed to work only on school campus buildings
Off-Campus To work for any Canadian company off-campus during your studies, you:
Must be a full-time post-secondary student studying in a program that will lead to a certificate, diploma or degree at a Designated Learning Institution (DLI)
May continue working if you are in your last semester as a part-time student because you do not need a full course-load to complete the program and you have been a full-time student since you started
Are allowed to work off-campus up to 20 hours per week during the regular school semesters while studying, and 40 hours per week during school breaks (summer and spring)
Cannot work off-campus if your studies are English or French as a second language, general interest courses, preparation program courses, or you are a visiting or exchange student who will not obtain a degree at a Canadian institution
