On August 22, 2011, Canadian New Democratic Party leader and Leader of the Opposition Jack Layton died from an unspecified, newly diagnosed cancer. Prior to his recent diagnosis, Layton led his party to gain a historic rise in seats (from 37 seats to 103) during the 2011 federal election. His state funeral was held on Saturday, August 27, 2011 at Roy Thomson Hall in Toronto. Protocol does not mandate state funerals for a Leader of the Opposition as it does for Prime Ministers and Governors General, but Prime Minister Stephen Harper used his discretion to offer the honour, via the Governor General-in-Council, to Layton's widow Olivia Chow. Layton's death sparked a wave of mourning from Canadians of various political beliefs.
In the early hours of August 24, the flag-draped casket was taken from Rosar-Morrison Funeral Home in Toronto with Toronto Police Service escort towards Ottawa. The hearse arrived in Ottawa, was greeted by a Guard of Honour of Royal Canadian Mounted Police officers, and the casket was taken into the Centre Block by pallbearers from the Guard of Honour to lie in state in the lobby for the House of Commons for two days. To a 15 gun salute, the cortege departed Ottawa to Gatineau, Quebec, and Layton's body was then moved to Toronto (via escort from Toronto Police) to lie in repose at Toronto City Hall. There, the casket was taken from the hearse by Toronto Police pallbearers into the Rotunda until Saturday's funeral.
