Working as an international student

[oggypops]

hello! I am currently accepted to a Universtiy Transfer Programme. I don't think that grants me permission to work in Canada. However, I will later be switching to an Associate Degree Programme which grants me permission.
My question now is, if I get my study permit using the Acceptance letter stating my programme as a Uni Transfer programme and then I change programmes, what are the procedures to ‘‘edit’’ my study permit to allow me to work?
