North York City Controller, 1972-1980 Greene was first elected to the North York Council in December 1972, winning a position on the city's
Board of Control, the first woman elected to the body. Her position on the Board of Control gave her an automatic seat on the
Metropolitan Toronto Council. Greene's first campaign was centred primarily around a zoning issue: she opposed a municipal
bylaw restricting cohabitation by people unless they were related or one person was an owner (she and her female housemates had been threatened with eviction under the terms of this bylaw). Greene also argued that she would speak for the rights of women, single persons, tenants and salaried workers. One of the first issues she was involved in was the Ambulance service. She fought a "one woman war" which resulted in the amalgamation of ambulances services in Metropolitan Toronto and the establishment of the Toronto Ambulance Service. She was re-elected to the Board of Control in 1974, 1976 and 1978 before standing down in 1980. As a result of topping the poll for the Board of Control (on which sat the Mayor and four Controllers elected at-large), Greene became the Deputy Mayor of North York in 1974. In this capacity she sat on the Executive Committee and Budget sub committee of Metropolitan Toronto and reviewed the budgets of numerous departments at various times including those of the Community Services and Housing departments, the Police and the Ambulance Departments. She also ran for the
Legislative Assembly of Ontario in the
1975 provincial election, losing to
New Democrat Odoardo Di Santo in
Downsview. Greene's support for cohabitation law reform placed her in opposition to North York Mayor
Mel Lastman, who initially supported her but then attempted to exclude boarding houses from the city. Following an eight-year legal battle conducted by lawyer Barry Swadron QC, on behalf of Doug Bell, a resident of North York who had been charged with living with other people to whom he was not related, the
Supreme Court of Canada upheld Greene's position and struck down the municipal
bylaw in April 1979. Greene favoured market-value assessment reforms for Metro Toronto properties, and criticized provincial
Treasurer Darcy McKeough for backing away from this proposal in 1978. In 1979, she spoke out against
tobacco advertising on the
Toronto Transit Commission. She also supported electoral reforms, including the abolition of regional Boards of Control and the direct election of the Metro Chair. She considered running against Lastman for
Mayor of North York in 1980, but declined on the grounds that she did not have the financial resources to conduct a successful campaign. She did not seek re-election to the Board of Control, and instead announced that she would enrol in a Master of Public Administration (postgraduate) program at
Harvard Kennedy School. Greene sought a prominent civil service position after returning to Toronto, but was unsuccessful and returned to teaching high-school English.
North York City Controller, 1982-1985 Greene returned to municipal politics in 1982, winning election to the second position on North York's Board of Control and receiving an automatic position on Metro's executive committee. She argued for cutbacks to the
Toronto Transit Commission's budget, arguing that it had become "out of control" by 1984. Greene supported the direct election of Metro Councillors, on the grounds that indirectly elected council members were not sufficiently accountable. She resumed her previous role as a prominent critic of Mel Lastman, arguing that his style of politics favoured backroom deals and often removed councillors from the decision-making process. Greene also called for the resignation of city planning commissioner Bruce Davidson in August 1983, arguing that his $265,000 debt to a major developer created a serious conflict-of-interest situation. She was one of only four councillors to oppose significant cutbacks to North York's public health department in June 1984, and was subsequently the only City Controller to support an
affirmative action program for city. Greene accused North York Councillor
Andrew Borins of improper behaviour in 1983–84, arguing that his family's property holdings put him in an undeclared conflict of interest over the proposed North York Civic Centre. Borins sued Greene for slander and Greene responded by charging Borins with Conflict of Interest. Borins was successful in the lower courts on 20 March 1984, but this decision was overturned on appeal. A Divisional Court judge subsequently upheld Greene's accusation, and stripped Borins of his council seat on 16 April 1985. She was offered the Progressive Conservative Party's nomination for
Eglinton—Lawrence in the
1984 federal election, but declined. Greene challenged Mel Lastman for
Mayor of North York in 1985, promising a more open government and arguing that Lastman had "den[ied] North York residents the right to participate in planning their neighborhoods". She was defeated by a significant margin, in a contest marked by undisguised animosity between the candidates. Greene returned to teaching after the election, teaching Media Studies, English and Dramatic Arts with the North York Board of Education. ==Member of Parliament==
