Previously, international students attending institutions in Canada could only hold jobs on their home campus. Now - presumably beginning this fall - students will be able to work wherever they want while attending university.
Also, in a related development, international student visa holders in Canada will now be able to obtain a two year post-degree work visa. Currently, upon completion of one's degree in Canada, international students can quite easily obtain a one-year work extension. Unfortunately for U of T'ers, this second change only affects students outside of Toronto, Vancouver, and Montreal.
