The City of Ottawa is planning the future of the Parliamentary Precinct.

"Ottawa city counsellor (for Somerset Ward), Gatineau mayor testify at Committee studying expanded parliamentary precinct." by Giacomo Panico, CBC News, May 31, 2022. "MP's hear case for making Wellington Street a pedestrian, Tramway zone." "Major overhaul in store for entire block facing Parliament" by Ryan Patrick Jones, CBC News February 3, 2020.

House of Commons Ottawa December 7, 1984 MP Joseph Gaston Isabelle (Hull-Aylmer) Liberal: "Several years ago you could see Parliament Hill from far away. Today you have to fly aboard a helicopter to see it, because of a few small skyscrapers that have, for all practical purposes, destroyed the beauty of the majestic Parliament Hill. And the National Capital Commission had to buy some land in order to have control over this area and avoid undesirable construction. That is what the Commission did among other things to avoid the building of huge skyscrapers which would have practically destroyed the beauty of Parliament Hill."

Prime Minister Pierre Trudeau never wanted high rise apartments and the demolition of buildings across from Parliament Hill: House of Commons Ottawa July 20, 1973 The Hon. Jean-Charles Dube (Minister of Public Works): "Concern has been expressed about the danger of visual encroachment on the beauty of the parliamentary precinct, which is one of the great symbols of Canada. We must ensure that nearby developments do not adversely affect it."

"We have all been aware that to properly house the expanded requirements of Parliament for the generations ahead in a way that would both complement and preserve the existing architectural beauty of the Parliament Buildings we must enlarge the present parliamentary grounds. I wish therefore to announce, Mr. Speaker, that I have today, on behalf of the government, filed a notice of intent to expropriate all the land and buildings in the area bounded by Wellington Street, Elgin Street, Sparks Street and Bank Street. The purpose of the expropriation as I have indicated is to protect the environment of Parliament from any development which could adversely affect it, and simultaneously provide the land for an appropriate expansion of parliamentary facilities and other government requirements. The property of the United States Embassy has been excluded from this expropriation but discussions are well advanced for its acquisition." 

Senate of Canada, Ottawa, December 12, 2019 Senator Serge Joyal: "Parliament Hill does not enjoy any legal protection. Not only does it not benefit from that protection but the immediate area is a jungle for development." 

Buildings that are facing demolition: "They have reached the end of their life cycle." Former American Embassy 100 Wellington (land beside the Embassy is now called infill); Embassy Annex 128 Wellington; Victoria 140 Wellington; Birks 107 Sparks; Valour 151 Sparks; Bate 109 Sparks; Marshall 14 Metcalfe; Canadian Imperial Bank of Commerce 119 Sparks; Fisher 115 Sparks; Canada's Four Corners 93 Sparks.

"The height limit for structures facing Wellington Street is 108 metres or 32 storeys, while the height limitation for buildings facing the Sparks Street Mall is 113 metres or 34 storeys" (Parliamentary and Judicial Precinct Area Site Capacity and Long Term Development Plan, page 89/148.) Until 1965 there was a height limit of 13 storeys in downtown Ottawa so that the Peace Tower could dominate the landscape.

I mentioned this before, the Parliamentary Precinct, Experimental Farm and Lebreton Flats are part of the National Interest Land Mass. "The Concept of National Interest Land Mass refers to lands of national interest, that is lands required for for the long term to support the unique functions of the Capital. This designation extends to all federally owned lands in Canada's Capital region, not just NCC-owned lands." 

House of Commons Ottawa November 23, 1967 The Hon. George McIlraith (Minister of Public Works): "The Lebreton Flats were envisioned as a western extension of the Parliamentary Precinct. Buildings on or near the Precinct cannot be any taller than the Peace Tower."

Eleven Block 2 buildings on Wellington Street that may be flattened.
