For seventy-five years, 24 Sussex Drive was the symbolic heart of Canadian politics, a stately residence where decisions were made, famous families grew up, and world leaders came to call. Today, it stands empty, stripped to the studs and haunted by neglect. 24 Sussex: The Past and Future of Canada’s Official Residence traces the building’s remarkable story, from its origins as a lumber baron’s mansion to its rebirth as Canada’s official residence after the Second World War, and finally to its current state of decay. Drawing on newly uncovered archival materials and interviews with former residents, historians, and architects, Dean Beeby and Ian Bailey reveal the political dramas, security challenges, and everyday moments that unfolded within the building’s walls, and unravel the politics and paralysis that have left this national landmark in ruins. They also examine how countries such as Japan and Australia view their official residences and confront the big question: should 24 Sussex be saved or replaced? With Canada’s sovereignty under threat, and a new patriotism focusing on symbols that bind the country, the authors argue that the fate of 24 Sussex has become a test of national resolve.
