Most of the businesses I've spoken to about temporary foreign workers would be happy to find ways to transition them to permanent status. They are happy with these people; they want them there. The problem often is that the programs that are in place to move those people from temporary to permanent status are not well adapted to their needs.
A lot of our permanent immigration programs are aimed at people with university degrees, high-skilled workers, and many of the temporary foreign workers we're bringing in are not necessarily in that category. If they could transition them into permanent status, I think many employers would.
