Three official residences within three kilometres of each other. One open as a museum because its owner has been dead for three quarters of a century. One empty and gutted because its institution has not decided what to do with it. One continuously occupied for one hundred and sixty-one years because the institution it represents still works. The corridor is the institutional record.
Start
Confederation Square: The Gate

The symbolic centre of the capital. The National War Memorial dedicated 21 May 1939 by King George VI. Looking north up Sussex Drive: the corridor begins.

The Fumihiko Maki and Moriyama Teshima Architects building opened by Stephen Harper on 6 December 2008. The first embassy of the walk. The first asymmetry.

David Childs of Skidmore, Owings and Merrill. Dedicated 8 October 1999. Foreign-power infrastructure on the corridor while the Prime Minister's residence two blocks north began its slow vacancy.

Eugène Beaudouin's 1939 Art Deco chancery. The first foreign chancery on Sussex Drive. The cornerstone was laid by Mackenzie King on Bastille Day 1936.

Joseph Merrill Currier built it 1866 to 1868 as a wedding gift. Federally expropriated 1943. PM residence 1951 to 2015. The 2021 NCC report. The 2023 abatement. The decision deferred.

Thomas McKay's firm built it 1855 to 1857 for his son-in-law John McKinnon. John A. Macdonald died here 6 June 1891. The British High Commissioner's residence continuously since 1930.

Thomas McKay's 1838 villa. The Crown leased it in 1864, Frederick Preston Rubidge oversaw additions in 1865, the Crown bought it in 1868. Every Governor General since Viscount Monck has lived here. The lights are on.
Weekday mid-morning, Tuesday through Thursday, between nine and noon, in shoulder season (late April through early June, September through October). Sussex Drive carries diplomatic and ceremonial traffic throughout the working week; the corridor is quieter on weekday mornings than on weekends, when the National Gallery and ByWard Market draw heavier foot traffic at the south end. The Tomb of the Unknown Soldier ceremonial guard rotates at Confederation Square in spring through autumn; the audio at Stop 1 is anchored to respect the guard's quiet zone. The Rideau Hall grounds at Stop 7 are open year-round during daylight hours; interior tours are by reservation. Avoid Sunday afternoons in summer when the south end of the corridor is congested with ByWard Market visitors. Winter walks the corridor with almost no foot traffic, but the wind off the Ottawa River bluff at Earnscliffe and Rideau Hall is sharp in January and February.
