Jean-Jacques Blais PC KC (/ˈbleɪ/ BLAY, French: [blɛ]; born June 27, 1940) is a former Canadian politician, who represented the riding of Nipissing in the House of Commons of Canada from 1972 to 1984.
Born in Sturgeon Falls, Ontario, Blais attended Ecole Sacré-Coeur and Sturgeon Falls High School before receiving a Bachelor of Arts degree in 1961 and a Bachelor of Laws degree in 1964 from the University of Ottawa.
In 1994, he was appointed chair of the Pearson Peacekeeping Centre, holding that position until he retired in 2002.
In August 2012, with the help of lawyer Mark Power, he contested the nomination of Auditor General Michael Ferguson, named in November 2011, on the grounds that, as a unilingual Anglophone, his nomination was illegal and unconstitutional.
The court action refers to article 16 of the Canadian Charter of Rights and Freedoms and the Official Languages Act.
