Life and career
She was married to Peter Woolstencroft, a university administrator and professor of political science at the University of Waterloo. She taught a wide range of classes, from advanced Shakespeare classes in high schools to basic literacy and life skills courses for adult learners. In addition to a long-term teaching career at Conestoga College in Waterloo Region, she taught courses on environment issues and problem-solving at the University of Waterloo.
She received many awards for her political and community service, most notably the Queen Elizabeth II Diamond Jubilee Medal and the Jack Young Civic Award, Waterloo Region's highest recognition for civic service. Her commitment to enhancing the quality of the environment in Waterloo resulted in the city being cited as the Greenest city in Ontario by TVO. The Grand River Conservation Authority awarded her a posthumous award in the fall of 2013 to honour her environmental leadership in her forty years of community work and public service.
In the 1985 Ontario election, she was a candidate for the Progressive Conservative Party of Ontario in Waterloo North, and was defeated. She also stood as the candidate for the Progressive Conservative Party of Canada in the 1993 federal election in the riding of Waterloo, and in the 1997 federal election in the riding of Kitchener—Waterloo; she was defeated both times.
Woolstencroft served as a trustee on Waterloo County Board of Education (1970–1972, 1974–1985), including being elected chair from 1979 to 1982. She also served as President of the Association of Large School Boards in Ontario in 1984 and 1985.
Her tenure as mayor was dominated by the RIM Park scandal, involving the financing of RIM Park with a loan from MFP Financial Services of Mississauga, a deal which had occurred before her time as mayor but which she had supported as a councillor. This ultimately led to a full judicial inquiry of the RIM Park deal, at which Woolstencroft testified and argued she had merely been a "peripheral councillor on this".
During her time as mayor, the city of Waterloo entered into agreements that resulted in the establishment of the Perimeter Institute, the Centre for International Governance Innovation, and the Research and Technology Park at the University of Waterloo.
Woolstencroft died May 13, 2013 at the age of 69.
