From what we've heard so far, Her Excellency Governor General Michaelle Jean attached no conditions when she granted Harper's plea to shut down parliament until the end of January.
If anyone needs to be kept on a short leash during the hiatus it's Furious Leader Harper. Has the GG done anything to ensure that Harper can't exploit the obvious opportunity to rule by fiat by, for example, stacking the Senate? This is a guy who's shown he'd game his kids' lunch money if he saw political advantage to be had.
The House of Commons doesn't trust Harper and neither do an awful lot of Canadians. Let's hope that Jean hasn't just bent us over a barrel.
