I quite agree with buliwyf - for people with a business/IT background and with management experience. In this case survival jobs are wasted time and just show a poor preparation - regardless where you are in Canada. If you do it right, you bring enough money to cover your first year that you don't need a survival job and you start setting up your network. During this time you concentrate to get into your field by shaping your CV, application tactics, maintain your relationship to potential recruiters, employers, etc. - This is more than a full-time job if you do it right!
As a recruiter I can understand if someone who just has come to Canada is unemployed and is still looking for a job or still getting settled. I would have a hard time to hire someone for an experienced office/management job who currently works as a burger flipper, though. It would make me suspicious why he's doing it. (No, to me it doesn't show willingness to work hard. It shows someone misjudged his immigration and underestimated the complexity or entire situation.). Frankly, I wouldn't even bring this up in my CV... - Again, this all refers to people who held management positions back in their home countries...
