Davis initially named Welch to be his own successor as Education Minister on March 1, 1971. In this capacity, he was responsible for drafting policy guidelines on funding for Ontario's Roman Catholic school system. After another convincing victory in the 1971 provincial election, he was named as Provincial Secretary for Social Development on February 2, 1972. The Social Development portfolio was a newly created "super-ministry", and was intended to provide Welch with supervisory powers over the departments of Education, Health, Universities and Colleges and Social and Family Services. Though it was a powerful position in principle, it carried no direct administrative responsibilities and led to a reduced profile for the minister. Welch was often forced to remain silent in the legislative question period, while ministers under his watch responded to members of the opposition. He returned to a higher profile position on November 7, 1973, when Davis gave him additional responsibilities as Minister of Housing. In this capacity, he oversaw the cancellation of the Davis government's "Cedarwood" project near Pickering. Following a cabinet shuffle on February 26, 1974, Welch was promoted to Attorney General and Provincial Secretary for Justice. The latter position gave him supervisory powers over the departments of Correctional Services, Consumer and Corporate Affairs and the Solicitor General. He was also named Minister of Culture and Recreation on January 14, 1975, and was relieved of his other two positions on July 18 of the same year. The Progressive Conservatives were reduced to a minority government in the 1975 provincial election, but remained in power due to divisions among the opposition parties. Welch was re-elected for the newly created Brock constituency, while the redistributed division of Lincoln was won by the Liberal Party. Welch was appointed Government House Leader after the election, giving him the responsibility for working with opposition parties to ensure the passage of government legislation. He was also retained as Culture and Recreation Minister, and served as Commissioner of the Board of Internal Economy from November 4, 1975 to April 29, 1977. The 1977 provincial election yielded another minority government for the Progressive Conservatives. Welch remained Culture and Tourism minister until August 16, 1978, when he was re-appointed as Provincial Secretary for Justice. He held this position until August 30, 1979, when he was named Minister of Energy. He also became Ontario's Deputy Premier on September 21, 1977, although this was not a cabinet position at
