Hi FKL,fkl said:He can apply for an open study permit while being in Canada Or he can even get admission to a school first and then apply for Open study permit. Mainly he needs his mother's study permit, proof of funds for his stay (only CIC requirement) and proof of relationship. Besides CIC may or may not ask for medicals (they often do not do that if you are already in Canada).
School normally won't insist upon study permit for giving admission. They would mainly ask for parent's status document.
One he receives a study permit, he can apply for a trv to enter exit Canada for the same period. That usually takes a month max for some one with a valid study / work permit.
Note that TRV is only required to leave and reenter Canada (except from US). If you are not leaving Canada and have a valid study permit, you can stay here till its expiry without the need of a TRV.
Thanks a lot for your advise.
As I know minor child accompany with parent have valid study permit do not need a study permit. In my case, my son still need a study permit and then apply TRV even he already had a valid visitor visa - multiple expired by end of Dec 2018.
