Source-derived summary

Charles Joseph Clark (born June 5, 1939) is a Canadian businessman, writer, and retired politician who served as the 16th prime minister of Canada from 1979 to 1980. He served as leader of the Official Opposition from 1976 to 1979 and from 1980 to 1983 and led the Progressive Conservative Party of Canada from 1976 to 1983, and again from 1998 to 2003.

Despite his relative inexperience, Clark rose quickly in federal politics. He was first elected to the House of Commons in 1972 and won the leadership of the Progressive Conservative Party in 1976. He led the party to a minority government in the 1979 federal election, defeating the Liberal government of Pierre Trudeau and ending 16 years of continuous Liberal rule. Taking office the day before his 40th birthday, Clark became the youngest prime minister in Canadian history.

Upon becoming prime minister, Clark introduced freedom of information legislation (which died upon the dissolution of Parliament) and oversaw the "Canadian Caper" rescue in response to the Iran hostage crisis; however, his tenure was brief as the minority government was brought down by a non-confidence vote on his first budget in December 1979. The budget defeat triggered the 1980 federal election. Clark and the Progressive Conservatives lost the election to Trudeau and the Liberals, who won a majority government and returned to power. As of 2026, he remains the most recent prime minister to have lost power following the defeat of his budget.

Editorial summary

This brief starts where responsible research should: with the source description of “Joe Clark” as 16th Prime Minister of Canada. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1939, 1979, 1980, 1976—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Clark, 16th and Prime can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 16th Prime Minister of Canada. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q128574. The first chronological checks are 1939, 1979, 1980 and 1976.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
