Which Ottawa address is the official residence of Canada's prime minister? The answer is 24 Sussex Drive.

The house stands in Ottawa's New Edinburgh neighbourhood, overlooking the Ottawa River and near Rideau Hall. It was built between 1866 and 1868 for lumberman and Member of Parliament Joseph Merrill Currier, who originally named it Gorffwysfa.

The Canadian government acquired the property during the 1940s and converted it into an official prime-ministerial residence. Louis St. Laurent became the first prime minister to live there in 1951. Since then, the address has become a familiar symbol of Canada's head of government, although it is primarily a home rather than the prime minister's office.

A modern complication often causes confusion: 24 Sussex has been vacant since 2015 because of its poor condition. Justin Trudeau and Mark Carney have lived at Rideau Cottage instead. Rideau Hall is the official residence of Canada's governor general, not the prime minister.
