David Matas ran for the House of Commons of Canada in the 1979 and 1980 federal elections as a Liberal candidate in Winnipeg—Assiniboine district and came in second place both times.

In 2009, Matas was a signatory to a letter opposing the appointment of Christine Chinkin to a UN Human Rights Council fact finding mission on the 2008-2009 Gaza War (also known as the Goldstone Commission), alleging that Chinkin signed a prejudicial letter that indicated that, without examining the evidence, she "concluded that Israel was acting contrary to international law.

In 1977, following the election of the separatist Parti Québécois government the previous year, he was asked to sit on the CBA Committee on the Constitution.
