I have the same question. I am from Country with the requirement "must be a resident of Country when applying". I have been in Canada since October 5 as Student, and I have the study permit valid until January 2016. I am planning to apply under IEC category Young professionals and have already all required documents collected. This concern has dumped my brain.
It is a bit confusing because among section generally asked questions is written that a person can apply for Work permit while holding a study permit.
Please, if somebody know the answer, respond to this post.
