^^^ This is why the neighborhoods always described as <country>town are so useful in big cities like TO. It gives immigrants whether refugees or not a place where they can learn about how Canada works in somewhat familiar surroundings. There is a downside of course, often poor accommodation, for some groups bad employers, still better than no jobs and for groups that tend to sequester women it gives the women even less chance of integrating.
Your Lawyer example, he may never be called to the bar in Canada but starting within his local community he, who is obviously smart, could work his way into a good job...but if the 'system' were to dump him in rural Manitoba ( just an example!!) that would not work.
