I already got my study permit and got into canada a few days ago, however, for some reasons probably I do not wish to continue at my current canadian university. So if I withdraw from my current university and get out of canada, and after years I got accepted into another university in canada, do I need to apply for a new study permit? And if I do withdraw from my current university and re apply a study permit in the future, is there any negative factors may affect my future study permit application? Thanks a lot.
