24 Sussex Drive has also been proposed. The designation as a federal heritage building, though not legally binding, would probably protect it against such a measure. 24 Sussex Drive 24 Sussex Drive, originally called "Gorffwysfa" and usually referred to simply as 24 Sussex, is the official residence of the Prime Minister of Canada, located in the New Edinburgh neighbourhood of Ottawa, Ontario. Built between 1866 and 1868 by Joseph Merrill Currier, it has been the official home of the Prime Minister of Canada since 1951. It is one of two official residences made available to the prime minister, the Harrington Lake estate in
Gatineau Park and deciduous forests to windswept savannas. The mountain is also home to a number of trees which are rare in the area, including some that are nearly 600 years old. For many years, a red-coloured cedar cross was located on top of King Mountain. Originally erected by Old Chelsea's parish priest, Father Maguire, it could be seen for miles around. It eventually rotted and fell over the cliff. Gatineau Park provides habitat for many species of birds including the pileated woodpecker and common loon. Turkey vultures and migrating hawks may be observed soaring on the thermals above the Eardley Escarpment.
