No, you don't. Nor is there any harm in telling your recruiter. Some apartment complexes may charge a little extra for double occupancy but that will be the only issue. Unless he barks continuously home alone while you are working. Then you may have a problem.
P.S. It is usual on this side of the border to spell traveler with only one "L". Canadians and other Commonwealth type countries are good with extra "L"s, but we try to conserve bandwidth here. ;-)
