He attended the University of Adelaide, later earning a master's degree in urban planning from the University of Liverpool under a Colombo Plan scholarship.

Ong joined the People's Action Party and secured a seat in Parliament during the 1972 general election, representing the Kim Keat constituency. Over two decades, he held multiple high-level government roles, including Minister for Communications from 1978 to 1981 and Minister for Labour from 1981 to 1983. He reached the position of Deputy Prime Minister in 1985, serving in that capacity until 1993. Simultaneously, he served as the Chairman of the People's Action Party from 1981 to 1993.
Infrastructure Advocacy
During his tenure as Minister for Communications, Ong was the primary proponent of the Mass Rapid Transit system. Despite significant opposition from other cabinet members, including Finance Minister Goh Keng Swee and Trade and Industry Minister Tony Tan, who cited financial concerns and construction industry saturation, Ong maintained that a bus-only transit network would be insufficient for Singapore. His perseverance led to the government approving the project in May 1982, initiating what was then the largest construction undertaking in the country.
Labour Leadership and Presidency
From 1983 to 1993, Ong served as the Secretary-General of the National Trades Union Congress. In 1993, he resigned his parliamentary seat and party affiliation to compete in the presidential election. Winning 58.7% of the vote, he was sworn in as Singapore's first directly elected president on 1 September 1993. Following the death of his wife and his own health issues, he chose not to seek a second term. He died from lymphoma in 2002 at age 66.
