He was born in Kapuskasing, Ontario, the son of Wyatt Dick and Constance Grace Harrison, and educated in Arnprior, Port Hope, at the University of Western Ontario and the University of New Brunswick. Dick was called to the Ontario bar in 1969. He served as assistant crown attorney for Carleton County from 1969 until 1972, when he entered private practice in Ottawa. In 1981, he was named Queen's Counsel.
Dick was first elected to the Canadian House of Commons in the 1972 general election as the Progressive Conservative Member of Parliament for Lanark—Renfrew—Carleton. In 1983, he became Deputy House Leader of the parliamentary Opposition Tory party.
He was appointed a parliamentary secretary following the Tory victory in the 1984 general election under Prime Minister Brian Mulroney. In 1986, Dick was promoted to Cabinet as Associate Minister of National Defence.
When Kim Campbell succeeded Mulroney as prime minister in June 1993, she retained Dick as Supply and Services minister, while adding an appointment as Minister of Public Works. However, both Dick and the Campbell government were defeated in the subsequent 1993 election, which ended his political career.
At 53 and with most of his adult life having been consumed by politics, Dick found himself out of work and with his political experience counting for little in job interviews. After being turned down for executive or management level positions, Dick found entry-level work at a stock brokerage firm. Dick was successful and now earns a six-figure salary. The story of Dick's life after politics is one of those profiled in the 2003 book The Dark Side: The Personal Price of a Political Life by Steve Paikin ISBN 0-670-04328-1.
