The six-month rule requires both duration and completion timing
Canada identifies study of six months or less that can be completed within six months as a situation that generally does not require a study permit. Weeks on the enrolment form, make-up classes, delayed start and intended stay can change the assessment; do not infer from a school’s word ‘short-term’ alone.
A study permit, visitor document, eTA or visa are not one layer
The travel document depends on passport and travel mode, while a study permit depends on the actual study arrangement. Check Study in Canada, study-permit and travel-requirement tools separately before paying for course, flight and housing; confirmation of one step does not substitute for another.
Make Canadian course records into a field-by-field check
Course name, DLI or school information, campus, start and finish, tuition, payment status and housing address should match personal application information. If extending, transferring or changing course in Canada, use current official and school directions for the next step instead of relying on an old letter for a new arrangement.
