Education and diplomatic career
In 1992, he was appointed ambassador to Germany. In the Department of Foreign Affairs in the late 1990s, he was the senior official responsible for the development of the Canadian human security agenda. He led the Canadian task forces on the Zaire and the Kosovo conflicts, participating in the diplomacy that ended the Kosovo war. He also served as chief negotiator of the Kyoto Protocol to the International Climate Change Convention.
In 2000, Heinbecker was appointed Canadian representative to the United Nations. There he was a strong proponent of the International Criminal Court and argued for compromise to avoid the Iraq War of 2003.
Heinbecker is a Distinguished Fellow at the Centre for International Governance Innovation and the inaugural director of the Centre for Global Relations at Wilfrid Laurier University.
Heinbecker gained media attention in 2003 when he promoted a Canadian compromise at the United Nations which, if successful, would have obviated the Iraq war. A frequent commentor on Canadian foreign policy, he is the author or editor of numerous articles and books. In 2005, he criticized fellow diplomat Franco Pillarella for the latter's claim that he was unaware that Maher Arar was being tortured in Syria or that torture was even practised there. 
On October 12, 2010, Foreign Affairs Minister Lawrence Cannon said "Not being able to speak with one voice as a country had a negative impact on Canada's bid" for a seat in the United Nations Security Council, with reference to Liberal leader Michael Ignatieff's comments, which included "I know how important it is for Canada to get a seat on the Security Council, but Canadians have to ask a tough question: 'Has this government earned that place?' We're not convinced it has." On October 13, Heinbecker said that the failure to win a seat was the result of the government's policies, not of Ignatieff's criticism.
