Sarah Elizabeth Coyne
Sarah Elisabeth Coyne is a Canadian citizen and an alumnus of the Economics program at the Wharton School, in Pennsylvania. Both her parents were Canadian Constitutional scholars. Her mother, Deborah Coyne, played a key role in Canada's Meech Lake Accord. Her father was Pierre Elliott Trudeau, the Prime Minister of Canada who patriated Canada's Constitution.
In 2010 the Toronto Star profiled 19 year old Coyne, while she was studying Economics, at the Wharton School, at the University of Pennsylvania.  According to a 2010 profile in the Hamilton Spectator Coyne has generally lived a quiet, private life, with the exception of publicly helping her mother run for a seat in the Parliament of Canada. Coyne attended University of Toronto Schools.
The Spectator reported that Coyne had had little contact with her older half-brothers, whose mother is Margaret Trudeau. The Spectator reported that nine-year-old Coyne was embraced by both former President Jimmy Carter and Cuban President Fidel Castro at her father's funeral. The Spectator reported that she was not mentioned in the eulogy her half-brother Justin Trudeau delivered at her father's funeral.
In his account of her father's friendship with Fidel Castro, Richard Wright described Carter speaking privately with Sarah, at her father's funeral, hugging her, and telling her she was a "brave girl".
Her mother, Deborah Coyne, put her name forward as a candidate for the leadership of the Liberal Party of Canada in June 2012, and her half-brother Justin Trudeau put his name forward in September 2012.
Margaret Wente profiled Coyne's mother in the Globe and Mail on January 15, 2013, based on her recently published memoirs, Unscripted: A Life Devoted to Building a Better Canada. According to Wente, Deborah Coyne and Pierre Trudeau had been involved in a relationship for over five years, and after the birth of their child, Trudeau treated Sarah "like a distant uncle":
- “He made it clear from the beginning that the boys were his first priority and that remarriage was out of the question... He stressed that Sarah and I wouldn’t be able to just come by his home any time we wanted to.”
According to the National Post during the Federal election campaign that led to her older brother Justin becoming Prime Minister of Canada, Coyne told reporters “it’s not something I’ve thought about,” when asked if she had political ambitions of her own.
In her PhD thesis on the legal aspects of advances in reproductive technology Roxanne Mykitiuk compared the reaction to older women using these technologies to bear children at older ages to that of the reaction that to her father Pierre, siring Sarah at 71. She noted that some reproductive scientists referred to women who wanted to use technology at relatively advanced ages were referred to as "frankensteins", while Trudeau earned praise and admiration.
After graduating from the Wharton School, at the University of Pennsylvania, with a degree in Economics, Coyne worked for investment banking firms, including Goldman Sachs. Most recently she is a Vice President at ValueAct Capital.
