It's networking. It's having a professional in their field look at their résumé, coaching them through interviews, helping them know the right websites to look for in a particular field, where the right places are, which companies in their field are growing, who are the right people to talk to, and getting exposed to the Canadian workplace. Often the mentors do mentoring in their workplace, so people get a chance to be exposed to the environment.
