Canadian peers and baronets (French: pairs et baronnets canadiens) exist in both the peerage of France recognized by the Monarch of Canada (the same as the Monarch of the United Kingdom) and the peerage of the United Kingdom.

In 1627, French Cardinal Richelieu introduced the seigneurial system of New France. Almost all of the early French Canadians who came as officers in the military or filled important official positions within the colony in New France came from the ranks of the French nobility. Under the Ancien Régime, several of these men were promoted to more senior ranks within the peerage of France. From the early 1700s, it became customary for the governors of New France to be given the title marquis. Except for the Marquis de Vaudreuil and the Marquis de Beauharnois, most were in Canada only for a few years before returning to France and are therefore not counted as Canadians.

The Baronetage of Nova Scotia (a British hereditary title, but not a peerage) had been devised by King James VI and I in 1624 as a means of settling Nova Scotia. Except for Sir Thomas Temple, almost none of them came to Nova Scotia, therefore they are counted as British, not Canadian.

Following the British Conquest of New France in 1763, the likes of The 1st Baron Amherst and The 1st Baron Dorchester were raised to the Peerage of Great Britain for their part in the taking of Canada and as Governors General of Canada, but they were not Canadians. As the colony grew under British rule both in terms of geography and economy, baronetcies began to be conferred upon various Canadian politicians, military commanders and businessmen.

In 1891, Lord Mount Stephen became the first Canadian to be elevated to the peerage of the United Kingdom. The significant losses of the First World War included many direct heirs to titles and some replacements were found in Canada, resulting in the acquisition of titles by Canadians.

After the controversial elevation of Lords Atholstan and Beaverbrook to the Peerage of the United Kingdom, the Nickle Resolution was presented to the House of Commons of Canada in 1917 requesting the Sovereign not to grant knighthoods, baronetcies or peerages to Canadians. This triggered the Canadian titles debate and led to a separate system of orders, decorations, and medals for Canada. Canadians who were granted peerages after that date had to hold or acquire British citizenship, such as The 1st Baron Thomson of Fleet. However, the 1946 Canadian Citizenship Act provided that Canadians who acquired another citizenship by any means other than marriage had renounced their Canadian citizenship. The 1977 Citizenship Act undid this provision.

• Baron de Longueuil. Created in 1700 by King Louis XIV for Charles le Moyne de Longueuil, the Canadian born Governor of Trois-Rivières and afterwards Montreal. It is currently the only extant French colonial title as recognized by King Charles III. The 3rd Baron's only daughter became the 4th Baroness de Longueuil and married the nephew (Captain David Alexander Grant) of her step-father, William Grant, of Quebec. The 10th Baron's wife, Ernestine Bowes-Lyon, was a first cousin of Queen Elizabeth The Queen Mother.^[1] The present holder is Michael Grant, 12th Baron de Longueuil.^[2]

• Baron de Poboncoup. Created in 1651 or 1653 for Philippe Mius d'Entremont, the first of the d'Entremonts of Nova Scotia.^[3] The barony of Pobomcoup remained in the family until the expulsion of the Acadians that began in 1755 by the British.^{[citation needed]}
• Comte de Saint-Laurent. Created in 1676, for Michel-François Berthelot, King's Secretary in Paris and Commissary General of the French Artillery. In 1702, he sold the Île d'Orléans to Charlotte-Françoise Juchereau de Saint-Denys (1660–1732), sister of Louis Juchereau de Saint-Denys. Another of their brothers was the grandfather of Louis Barbe Juchereau de Saint-Denys (1740–1833), created the Marquis de Saint-Denys in 1774; a first cousin of The Hon. Antoine Juchereau Duchesnay who was also a first cousin of the Marquis de Lotbinière mentioned below.^[4] From 1702, Charlotte-Françoise took the title Comtesse de Saint-Laurent and arranged for her eldest son to also bear the title, but she was unable to meet her obligations to Berthelot. A lengthy court case ensued between Quebec and Paris, and in 1713 the King ruled in Berthelot's favour.^[5] The title was however no longer used after 1913.^{[citation needed]}
• Marquis de Vaudreuil. Created in 1703, for Philippe de Rigaud Vaudreuil, son of the Baron de Vaudreuil in the Languedoc. Formerly a colonel in the Musketeers of the Guard, in 1687 he came to New France in command of the Troupes de la Marine, rising to become Governor of Montreal in 1702 and the Governor General of New France the following year, serving until his death at Quebec City in 1725. His sons were: (1) Louis-Philippe de Rigaud, Comte de Vaudreuil, father of Louis-Philippe, Marquis de Vaudreuil^[6] (2) Jean-Louis de Rigaud de Vaudreuil, Vicomte de Vaudreuil (3) Pierre de Rigaud, Marquis de Vaudreuil-Cavagnal, the first native Canadian (and last) Governor General of New France (4) François-Pierre de Rigaud Vaudreuil, the last French Governor of Trois-Rivières;^[7] (5) Joseph-Hyacinthe de Rigaud, 3rd Marquis de Vaudreuil, father of Joseph Hyacinthe François de Paule de Rigaud, Comte de Vaudreuil.^[7] The title was however no longer used.^{[citation needed]}

• Baron de Portneuf. Created in 1681, for René Robineau de Bécancourt. His son, Pierre Robineau de Portneuf, sold the land to his brother but retained the title. The brother died in 1715 and the barony passed back to Pierre's daughters. The title became extinct in 1729 after the death of the 2nd Baron de Portneuf, due to a lack of male heirs.
• Comte d'Orsainville. Created in 1685, for Jean Talon, the first Intendant of New France. He died unmarried in 1694, and the title passed to his nephew, Jean-François, son of his brother, Robert (aka François), and Anne Dubois, daughter of Antoine DuBois and Louise d'Eu, who was wed to Renée Turin, widow of a Michel Séguin, and who sold the land in 1696 to the bishop of Quebec, Jean-Baptiste de La Croix de Chevrières de Saint-Vallier.^[8][9]
• Baron de Beauville, Acadia. Created in 1707, for François de Beauharnois de la Chaussaye, a member of the House of Beauharnais who served as Intendant of New France. He was a brother of the Marquis de Beauharnois. The Baron de Beauville died without issue in 1746 and as such the title became extinct.
• Marquis de Beauharnois. Created in 1725, for Charles de Beauharnois de la Boische, Governor General of New France from 1725 to 1746. He was a brother of the previously mentioned Baron de Beauville. He died unmarried in 1749, when the title became extinct.
• Marquis de Lotbinière. Created in 1784, for Michel Chartier de Lotbinière, the only Canadian by birth to have been elevated to that rank in the Peerage of France, and the last such creation made by Louis XVI. After the British Conquest of New France in 1763, de Lotbinière had added to his existing seigneuries by purchasing Rigaud and Vaudreuil from his father's first cousin, the Marquis de Vaudreuil-Cavagnal.^[10] He was the uncle of the Vicomte de Léry. He was a first cousin of Nicolas Renaud d'Avene des Meloizes (1729–1803) who sold their grandmother's Seigneury at Neuville and moved to France, where in 1769, he married the heiress Agathe-Louise de Fresnoy, and became the Marquis de Fresnoy. Another of his first cousins, The Hon. Antoine Juchereau Duchesnay, was also a first cousin of the previously mentioned Marquis de Saint-Denys. Lotbinière's son, Michel-Eustache-Gaspard-Alain Chartier de Lotbinière, inherited but did not use the title in order to keep political favour with the British. The de jure 2nd Marquis de Lotbinière was the father of three daughters, from whom descend the de Lotbinière-Harwood and Joly de Lotbinière families. But, as he left no male heir the title became extinct on his death at Montreal in 1822.^[11]
• Vicomte de Léry. Created in 1818, for Général François-Joseph Chaussegros de Léry, grandson of Gaspard-Joseph Chaussegros de Léry, whose wife was a first cousin of the previously mentioned Marquis de Saint-Denys. He was born at Quebec City, a nephew of the Marquis de Lotbinière. He fought as a general during the Napoleonic Wars. He was Engineer-in-Chief of Napoleon's Armies and Commander-in-Chief of Napoleon's Armies in the Netherlands. On his death, his name was on the list of officers being considered to fill the position of Marshal of France.^[12] In 1811, he was created a Baron d'Empire.^[13] In 1818, on the restoration of Louis XVIII of France, Chaussegros de Léry was created Vicomte de Léry and given the Grand Cross of the Legion of Honour.^[12] In 1801, he married Marie Cécile, daughter of Général François Christophe de Kellermann, 1st Duc de Valmy; Marshal of France. He retired to Château d'Etry at Annet-sur-Marne and is one of the 660 personalities whose names are engraved on the Arc de Triomphe at Paris. He was succeeded by his son, Gustave Chaussegros de Léry (1802–1850), who married a daughter of the Marquis de Somery, but died without children and as such the title became extinct.

• Baron Strathcona and Mount Royal, of Mount Royal in the Province of Quebec and Dominion of Canada and of Glencoe in the County of Argyll. Created in 1897 for Donald Smith, 1st Baron Strathcona and Mount Royal. He was one of the foremost builders and philanthropists in the British Empire. He was Governor of the Hudson's Bay Company, president of the Bank of Montreal, co-founder of the Canadian Pacific Railway with his first cousin Lord Mount Stephen, and Canadian High Commissioner to the United Kingdom. He built a home in the Golden Square Mile and Glencoe House. He leased Knebworth House and kept Colonsay House (still lived in by his descendants) as a summer home. By a new creation in 1900, his only daughter, Margaret Charlotte Smith, became the 2nd Baroness Strathcona and Mount Royal. The title is currently held by Donald Alexander Euan Howard.
• Baron Shaughnessy, of the City of Montreal in the Dominion of Canada and of Ashford in the County of Limerick. Created in 1916 for Thomas Shaughnessy, 1st Baron Shaughnessy. A native of the United States, he came to Montreal in 1882 where he became the 3rd president of the Canadian Pacific Railway from 1899 until his death in 1923. On the outbreak of World War I he threw his and the C.P.R.'s full support behind the war effort, for which he was awarded his peerage. He lived in the Golden Square Mile. The title is currently held by his great-grandson, the actor Charles George Patrick Shaughnessy, 5th Baron Shaughnessy.
• Baron Beaverbrook, of Beaverbrook in the Province of New Brunswick in the Dominion of Canada and of Cherkley in the County of Surrey. Created in 1917 for Sir Max Aitken, 1st Baronet. A native of New Brunswick and already a successful businessman, in 1910 he left Montreal for Britain where he became a press baron and Member of Parliament. George V was upset with his elevation to the peerage and it was met with scepticism in Canada, but it was nowhere near as controversial as that of his friend listed below, Lord Atholstan.^[14] During World War I, he was Minister of Information. During World War II, Lord Beaverbrook was Minister of Aircraft Production, Minister of Supply, Minister of War Production and Lord Privy Seal. The title is currently held by his grandson, Maxwell Aitken, 3rd Baron Beaverbrook.
• Baron Morris, of St John's in the Dominion of Newfoundland and of the City of Waterford. Created in 1918 for Edward Morris, 1st Baron Morris, Prime Minister.

• Baron Mount Stephen, of Mount Stephen in the Province of British Columbia and Dominion of Canada, and of Dufftown in the County of Banff. Created in 1891 for George Stephen, 1st Baron Mount Stephen. He was the president of the Bank of Montreal and the financial genius behind the creation of the Canadian Pacific Railway, once "the world's greatest transportation system". He was the first Canadian to be elevated to the Peerage of the United Kingdom and a first cousin of Lord Strathcona. Both he and his first cousin were particularly remembered for their philanthropy, between them donating many millions of dollars to charity. His home in the Golden Square Mile is today the Mount Stephen Club and from 1888 he moved permanently to England where he lived at Brocket Hall. His second wife, a niece of Lord Wolverton, was a lifelong friend and confidante of Queen Mary, whose mother she had served as a lady-in-waiting. The daughter he and his first wife adopted, Alice, married Henry Northcote, 1st Baron Northcote. Lord Mount Stephen left no male heirs and as such his title became extinct on his death at Brocket Hall in 1921.
• Baroness Macdonald of Earnscliffe, in the Province of Ontario and Dominion of Canada. Created in 1891 for Agnes Macdonald, 1st Baroness Macdonald of Earnscliffe, the widow of Sir John A. Macdonald, the 1st prime minister of Canada after Confederation in 1867. Her peerage was heritable by her heirs male, but she herself was only survived by a daughter, and so the title became extinct on her death in England in 1920.^[15] Her late husband, of whom she was the second wife, was also survived by one son from his first marriage, Sir Hugh John Macdonald, but he was not eligible to inherit the title from his stepmother.
• Baron Haliburton, of Windsor, in the Province of Nova Scotia and Dominion of Canada. Created in 1898 for Arthur Haliburton, 1st Baron Haliburton. He was born at Windsor, his family's home since 1763. After his education he went to England where he was a civil servant, rising to under-secretary of state for war and deputy lieutenant of London.

• Baron Atholstan, of Huntingdon in the Province of Quebec in the Dominion of Canada and of the City of Edinburgh. Created in 1917, for Hugh Graham, 1st Baron Atholstan, a staunch imperialist, one of the Conservative Party's largest fund-raisers and arguably the most powerful media executive in Canada in his capacity as owner of the Montreal Star. He was born at Huntingdon, Quebec, and after his education lived for the remainder of his life in Montreal. He was the only Canadian peer of the United Kingdom to have lived his whole life in Canada. However, his elevation to the peerage, for which he owed much to the machinations of his friends Lord Beaverbrook and Lord Northcliffe, was controversial in Canada and against the wishes of both the Governor General (the Duke of Devonshire) and Prime Minister Robert Borden.^[14] He was the father of one daughter but left no male heirs, and the title became extinct on his death at his home in the Golden Square Mile, 1938.^[16]

• Baron Coleraine, of Haltemprice in the East Riding of the County of York. Created in 1954 for Conservative politician Richard Law, the son of Bonar Law, a Conservative prime minister. Like Hugh Molson (see below), Richard Law was born in England to a father born in Canada.

Created in 1941 for Richard Bedford Bennett, a native of New Brunswick and the 11th Prime Minister of Canada who revived the awarding of Imperial honours to Canadians during the 1930s. He afterwards retired to England and the title became extinct on his death at Mickleham, Surrey in 1947.^[17]

A life peerage is not an hereditary title. The title lasts as long as the recipient of the honour is alive. The recipient's children can style themselves with the prefix 'honourable' but they cannot inherit the baronial title.

• Baron Black of Crossharbour, of Crossharbour in the London Borough of Tower Hamlets. In 2001, Tony Blair advised Queen Elizabeth II to confer on Conrad Black the dignity of a life peerage with the title of Baron Black.^[18] Canadian Prime Minister Jean Chrétien gave the opinion to his government's nationality department that a Canadian citizen should not receive a British titular honour, citing the 1919 Nickle Resolution. Black at the time held both Canadian and British citizenship. After the Federal Court of Canada ruled against Black in his suit against Chrétien, Black renounced his Canadian citizenship in 2001, remaining a citizen of the UK. In 2007, in Chicago, Conrad Black was sent to jail for six years after being convicted of defrauding investors. He was released in May 2012 following an appeal, after spending three years in a prison in Florida.^[19][20] He has since been expelled from the Queen's Privy Council for Canada and removed from the Order of Canada. In an interview with Peter Mansbridge in May 2012, Black said he would consider applying for Canadian citizenship "within a year or two" when he hoped the matter would no longer be controversial and he could "make an application like any other person who has been a temporary resident."^[21] Black regained his Canadian citizenship in April 2023.^[22] Black ceased to be a member of the House of Lords on 9 July 2024 under the House of Lords Reform Act 2014 because of non-attendance in the preceding session of Parliament.^[23]

John Molson (1787–1860), of Belmont Hall, Montreal.

From 1966, Lestor had sat for Eton and Slough and then for Eccles, during which time she held ministerial office, before retiring at the 1997 general election.
