Vistos
STUDY VISA
For studies lasting more than six (06) months it is necessary to obtain a temporary resident visa, under the category:
Study visa.
STUDY PERMISSION
And for studies in the province of Québec it is necessary to obtain a study permit, the CAQ- certificat d'acceptation du Québec

PERMANENCE
The visa is taken on Brazilian soil and has a certain validity but it does not necessarily mean that you can stay on Canadian soil all that time.
So only when you travel, the Canadian official will determine the length of stay for that period, and will stamp the validity on your passport. Usually for a student visa the length of stay is the same as the visa, so it is easy to get confused.
