I don’t think Justin Trudeau and his family have lived there since he was first elected PM in 2015. Instead they split their time between two other official residences. One is more or less across the road (Sussex Drive) on the grounds of the Governor General. That one is called Rideau Cottage but it’s a full sized house. Their other frequent stay is out of town at Harrington Lake in Gatineau, Quebec.
The Harpers were living at 24 Sussex Drive but started to make a list of things needing renovation, nothing much has been done. I think behind the scenes they have already decided to tear the place down and put up a more modern style of home suitable for future prime ministers.
The home most suitable for this prime minister is about a hundred miles south, namely Kingston Penitentiary.
The Liberal Party of Canada is a criminal enterprise.
