Parliament Hill in the context of "Privy Council Office (Canada)"

Patriation is the political process that led to full Canadian sovereignty, culminating with the Constitution Act, 1982. The process was necessary because, at the time, under the Statute of Westminster, 1931, and with Canada's agreement, the British Parliament retained the power to amend Canada's British North America Acts and to enact, more generally, for Canada at the request and with the consent of the Dominion. That authority was removed from the UK by the enactment of the Canada Act, 1982, on March 29, 1982, by the Parliament of the United Kingdom, as requested by the Parliament of Canada.

A proclamation bringing the Constitution Act, 1982, into effect was signed by Elizabeth II, as Queen of Canada, Prime Minister Pierre Trudeau, and Minister of Justice Jean Chrétien on April 17, 1982, on Parliament Hill in Ottawa. The patriation process saw the provinces granted influence in constitutional matters and resulted in the constitution being amendable by Canada only and according to its amending formula, with no role for the United Kingdom.

The Office of the Prime Minister and Privy Council (French: Bureau du Premier ministre et du Conseil privé) building, formerly known as the Langevin Block (French: Édifice Langevin, IPA: [lɑ̃ʒvɛ̃]), is an office building facing Parliament Hill in Ottawa, Ontario, Canada. As the home of the Privy Council Office and Office of the Prime Minister, it is the working headquarters of the executive branch of the Canadian government.

The term Langevin Block was previously used as a metonym for the Prime Minister's Office and the Privy Council Office. The building was named after Father of Confederation and cabinet minister Hector-Louis Langevin. Recognizing Langevin's role in establishing the residential school system, associated with the abuse of Indigenous children and attempts to forcibly assimilate them, Prime Minister Justin Trudeau announced the renaming of the building on June 21, 2017.

The Senate of Canada Building (French: édifice du Sénat du Canada) is a government building and former railway station that serves as the temporary seat of the Senate of Canada. Located at 2 Rideau Street in downtown Ottawa, it was known as Ottawa Union Station and served as the city's central railway station from 1912 until 1966. From 1966 to 2018, it was operated by the Government of Canada as the Government Conference Centre. The building currently includes a temporary Senate chamber (housed in the concourse of the former railway station), as well as some Senate offices and committee rooms (in the waiting room of the former station).

It is situated at the intersection of Wellington Street and the Rideau Canal, across the street from the Château Laurier hotel (which was constructed around the same time). It is 600 metres (2,000 ft) from Parliament Hill and Confederation Square.

The Second Supreme Court of Canada building sat to the west of Parliament Hill in Ottawa and was home to the Supreme Court of Canada from 1882 to 1945. The building was demolished in 1955 and the area became a parking lot and vehicle screening facility for Parliament Hill.

The Roaring Lion is a black and white photographic portrait of a 67-year-old Winston Churchill as Prime Minister of the United Kingdom. The portrait was taken in 1941 by Yousuf Karsh in the Centre Block on Parliament Hill in Ottawa, Ontario, Canada.

The Centre Block (French: Édifice du Centre) is the main building of the Canadian parliamentary complex on Parliament Hill, in Ottawa, Ontario, containing the House of Commons and Senate chambers, as well as the offices of a number of members of parliament, senators, and senior administration for both legislative houses. It is also the location of several ceremonial spaces, such as the Hall of Honour, the Memorial Chamber, and Confederation Hall.

Built in the Gothic Revival style, the present Centre Block is the building's second iteration. The first was destroyed by fire in 1916; all that remains of the original building is the Library of Parliament, at the rear of the Centre Block. Though construction began immediately after the blaze, sculpting work on the interior continued through the 1970s. Then, from 2018, MPs were moved elsewhere for renovations lasting until 2031.
