I'd put it a little bit the other way. We have the largest family class program in the world. We issue visitor visas to parents who are in process all the time; it's absolutely routine. As a matter of fact, if they're in process, they've generally already demonstrated that they have the financial capability to sponsor, so our officers issue five-year multiple entry visas to a lot of these cases.
Now, a lot of individuals are also refused. Normally, they're refused where the ties are very weak in the home country and the immigrant in Canada is not yet very well established and is probably not financially capable of sponsoring. There, you have a tricky call on the part of the visa officer, and some of those are refused.
