Nadon was nominated by Prime Minister Stephen Harper to be a puisne justice of the Supreme Court of Canada in October 2013.
His mother was of Ukrainian background whose parents immigrated to Canada from Ukraine during World War I.
She was a professional singer, including singing at the Château Frontenac during the big band era.
[3] Nadon chose his studies, though later claimed that he had turned down a draft offer from the Detroit Red Wings.
In 2013, it was reported that while Nadon was not actually drafted by the Detroit Red Wings, he did play with the Saint-Jérôme Alouettes, a Junior A team whose midget affiliates were part of the Red Wings’ farm team network.
[8] Nadon has been married for over 30 years to Margaret Buchan, a Scotswoman from the town of Peebles, Scotland.
[3] Nadon was admitted to the Bar of Quebec in 1974 and practiced law until 1993 at the firm of Martineau Walker (known today as Fasken), where he became a partner in 1981.
Nadon was a member of the Federal Courts Rules Committee for a number of years.
[8] Nadon's most outstanding ruling (in the opinion of a journalist) was written in 2010 when he found that the government of Stephen Harper had acted lawfully when it denied Omar Khadr repatriation from Guantanamo Bay prison, an offshore warehouse used by the US for detained terrorists.
The Supreme Court of Canada later agreed with his view that it was no business of theirs to mandate Khadr's repatriation.
[9] Nadon was nominated by the Conservative government of Prime Minister Stephen Harper to be a puisne justice of the Supreme Court of Canada.
[2] In January 2018, at a McGill University law school presentation hosted by the Runnymede Society, Nadon stated his view that the judiciary of Canada too often write their own interpretations of the 1982 Charter of Rights and Freedoms, and thus present their own notions of fairness as substantive law, instead of being guided by the text of the Charter.
