Located on Parliament Hill in Ottawa, Ontario, Canada, the Centennial Flame (French: Flamme du centenaire) commemorates Canada's 100th anniversary as a Confederation. The Flame was first lit as the climax of the centennial celebrations of January 1, 1967, in the presence of then Prime Minister Lester B. Pearson. He was joined on the hill by leader of the Opposition and former Prime Minister, John Diefenbaker, and Secretary of State, who was in charge of the Centennial, Judy LaMarsh as well as thousands of onlookers. The Flame is fuelled by natural gas and surrounded by a fountain whose ledge contains the shields of Canada's 13 provinces and territories—Nunavut was originally absent as it was not created until 1999. On December 13, 2017, a Nunavut plaque was unveiled.
