William Grenville Davis (July 30, 1929 – August 8, 2021) was a Canadian politician who served as the 18th premier of Ontario from 1971 to 1985. Behind Oliver Mowat, Davis was the second-longest serving premier of Ontario.

Born in Toronto, Davis was a lawyer before being elected as a Progressive Conservative member of provincial Parliament for Peel in the 1959 provincial election. He was a backbencher in the Conservative caucus until 1962, when he was appointed minister of education under John Robarts. During this period, Davis created the community college system and the educational television network now known as TVO.

In 1971, he succeeded Robarts as the premier of Ontario and held the position until resigning in 1985. He led the Progressive Conservatives to victory in four consecutive elections, winning two majority governments and two minority governments. As premier, Davis was responsible for the cancellation of the Spadina Expressway, the funding of Catholic secondary schools through grade 12, the formation of Canada's first Ministry of the Environment, and rent control, as well as playing a large role in the patriation of the Constitution of Canada.

Early life and education

Davis was born on July 30, 1929, at Toronto General Hospital, Toronto, Ontario, the son of Vera Mildred ( Hewetson) and Albert Grenville Davis. His father was a successful local lawyer. Davis married twice, first to Helen McPhee (1931-1962) in 1955, with whom he had four children (Neil, Nancy, Cathy, Ian). He then married Kathleen Mackay (1933-2025) in 1964; they had one daughter, Meg, in 1965.

Davis was politically active from the age of 15. Although Peel was an extremely safe Conservative seat for most of its history, Davis won by a narrow 1,203 votes. The election took place soon after the federal Progressive Conservative government of John Diefenbaker had cancelled the Avro Arrow program. <!--

Most of the 14,000 Canadians put out of work by this decision were residents of Peel, and many cast protest ballots against Diefenbaker by supporting Bill Brydon, the provincial Liberal candidate.

--> Davis was given the honour of move the motion to vote on the Speech from the Throne, which while purely symbolic, allowed him to give a speech that included two of his own planned projects: establishing what would become the Forks of the Credit Provincial Park, and improving education. Davis served for two years as a backbench supporter of Leslie Frost's government. When Frost announced his retirement in 1961, Davis became the chief organizer of Robert Macaulay's campaign to succeed him as premier and party leader. Macaulay was eliminated on the next-to-last ballot, and, with Davis, delivered crucial support for John Robarts to defeat Kelso Roberts on the final vote.

Minister of Education

Davis was appointed to Robarts' cabinet as Minister of Education on October 25, 1962, and was re-elected by a greatly increased margin in the 1963 provincial election. He was given additional responsibilities as Ontario's Minister of University Affairs on May 14, 1964, and held both portfolios until 1971. He significantly increased education funding during the 1960s; spending increased by 454% between 1962 and 1971 and hundreds of public schools were opened. Davis also oversaw a controversial overhaul and amalgamation of the outdated school board systems in the province, reducing the number of boards from 3,676 in 1962 to 192 by 1967.

During his tenure as education minister, Davis established new public universities, including Trent University and Brock University, as well as the public community college system. Canada's first educational research institute, the Ontario Institute for Studies in Education, and the Ontario Educational Communications Authority educational television network (now TVO) were established while he was Minister, in 1965 and 1970, respectively.

Davis's handling of the education portfolio, of which Robarts was a previous minister, made his entry into the leadership contest to succeed Robarts unsurprising. Robarts himself fully expected Davis to be his successor. He was immediately dubbed the frontrunner when he announced his bid on December 20, 1970. In the early hours of February 13, 1971, Davis defeated rival candidate Allan Lawrence by only 44 votes on the final ballot, after receiving support from third-place candidate Darcy McKeough. Following the convention, Davis brought Lawrence's campaign team, known as "the Spades", to become his principal advisors. The group later became known as the Big Blue Machine, and remained a dominant campaign force in the Progressive Conservative Party into the 1980s.
