Deborah Margaret Ryland Coyne (born February 24, 1955) is a Canadian constitutional lawyer, professor, and author. She holds a Bachelor of Laws degree from Osgoode Hall Law School of York University and a Master of Philosophy from Oxford University in international relations. On June 27, 2012, Coyne announced her candidacy for the leadership of the Liberal Party of Canada; she lost the leadership election in April 2013 to Justin Trudeau.
She was an employee in the Prime Minister's Office of John Turner, before spending two years teaching constitutional law at the University of Toronto Law School; she has also worked for the Business Council on National Issues, the Ontario Health Service Appeal and Review Board, and the Immigration and Refugee Board of Canada.
Opposition to the Meech Lake and Charlottetown Accords
Deborah Coyne took a role in opposing the Meech Lake Accord, a comprehensive package of constitutional amendments designed to gain the province of Quebec's formal acceptance of the Constitution Act, 1982. Coyne was among many prominent Liberals who disagreed with the Accord, including Pierre Elliott Trudeau, Donald Johnston and Jean Chrétien, although the issue split the federal Liberal caucus. She was a founding member of the Canadian Coalition on the Constitution, a grass-roots group that opposed the agreement. From 1989 to 1991, Coyne served as constitutional advisor to Newfoundland Premier Clyde Wells. Among the premiers, Wells was the staunchest opponent of the Meech Lake Constitutional Accord. Following the death of the Accord, partly at the hands of the Newfoundland House of Assembly, she opposed the Charlottetown Accord, a subsequent attempt to amend the Canadian constitution. The Charlottetown agreement was submitted to a national referendum in 1992 and was ultimately rejected by a majority of Canadian voters. Coyne led one of the "No" committees in the campaign and spoke widely against the deal.
Until the 2006 federal election was called, she was a member of the Immigration and Refugee Board of Canada. In that election, she ran in the electoral district of Toronto—Danforth as a Liberal Party candidate against New Democratic Party leader Jack Layton. Coyne finished second to Layton with 17,256 votes, or 34.2%.
In the next federal election, Coyne was nominated in April 2007 to again compete against Layton and Green Party candidate Charles Battershill. However, Coyne unexpectedly announced to her supporters via email on November 4, 2007 that she was withdrawing her candidacy because "it became clear that it was going to be very difficult to raise money from friends and family, who basically helped (her) out, to run a second time." She also stated that she "decided to bow out and refocus her energies on her consulting business." Nonetheless, on January 10, 2008, she filed her nomination papers for the riding of Don Valley West which was held by Liberal MP John Godfrey who announced on November 26, 2007 that he would retire in July 2008. Others interested in the nomination included former Liberal MP Sarmite Bulte, Abdul Ingar, a local imam, United Church Minister Rob Oliphant, and Jonathan Mousley, a former legislative assistant to former Liberal Cabinet minister David Collenette. In February 2008, Coyne accused Oliphant and Bulte's supporters of paying the requisite fees of members their respective campaigns had signed up, an act which is illegal under the Canada Elections Act if the candidate fails to disclose it. Coyne said that while she wasn't accusing Oliphant or Bulte of personally signing up new members improperly, every candidate must be held responsible for the actions of their representatives. On February 25, 2008, Coyne withdrew from the nomination race in Don Valley West and endorsed Rob Oliphant.
Coyne's interest in becoming the Liberal Party of Canada candidate in the riding of Ottawa West-Nepean became known in February 2014.
Liberal leadership campaign
On June 27, 2012, Coyne announced that she would be a candidate for leader of the Liberal Party of Canada, during the Party's 2012-2013 leadership contest. Her campaign was managed by blogger Jeff Jedras. 
Deborah Coyne is the cousin of journalist Andrew Coyne and actress Susan Coyne, and the niece of former Bank of Canada governor James Coyne. Deborah Coyne now lives with her family in Toronto. For years, she dated former Prime Minister Pierre Trudeau. Her daughter, Sarah Elisabeth Coyne, is Trudeau's only daughter, and was enrolled in the Wharton School of the University of Pennsylvania. Her son, Matthew, is the son of Canadian journalist Michael Valpy. Valpy and Coyne have since divorced.
