Royce Herbert Frith, CM QC (November 12, 1923 – March 17, 2005) was a Canadian diplomat, public servant, lawyer, broadcaster, and politician.
He was admitted to the Ontario Bar in 1949 and would become a partner in the Toronto firm of Magwood, Frith & Casey, specializing in litigation, municipal and broadcast and entertainment industry law.
[2] Frith successfully applied to the Board of Broadcast Governors in 1963 for a license to operate a new radio station in Windsor, Ontario.
He sat in the Upper House as a Liberal and served in various positions including Leader of the Opposition in the Canadian Senate and led the Liberals' filibuster against the introduction of the Goods and Services Tax forcing Prime Minister Brian Mulroney to use an obscure section of the Constitution to appoint extra Senators and ensure passage of the measure.
Frith also ensured the retention of Canada House in Trafalgar Square as the site of the Canadian high commission when the government had considered abandoning the location in order to save money.
