The federal government has launched a study of options to cut the flow of natural gas from Western Canada to the popular monument, and replace it with a more eco-friendly energy source.
Natural gas piped from the West has been bubbling through the fountain in the centre of the monument for 50 years, ever since it was unveiled by then-prime minister Lester Pearson on the eve of July 1, 1967, Confederation's 100th birthday.
