Jean Casselman Wadds (born September 16, 1920 in Newton Robinson, Ontario) is a former Canadian politician, who represented the electoral district of Grenville—Dundas from 1958 to 1968. She sat as a member of the Progressive Conservative Party.
She was the daughter of William Earl Rowe; Wadds and Rowe are, to date, the only father and daughter to sit as MPs in the same session of Parliament.
In 1946, she married Arza Clair Casselman, who represented Grenville—Dundas in the House of Commons until his death in 1958, and she was elected to the same seat later that year.
Wadds served as parliamentary secretary to the Minister of Health and Welfare in 1962 and 1963. She was the first woman to serve as a parliamentary secretary in the Canadian government.
In 1979, Wadds was appointed Canada's High Commissioner to the United Kingdom. She served in this capacity until 1983.
In 1982, she was made an Officer of the Order of Canada for carrying "out her duties with great competence and conscientiousness, particularly during the period of the patriation of the Constitution". [1]
