A familiar sound for locals, and a novel one for visitors, the Heritage Horns have sounded the first four notes of O Canada every day at noon at Canada Place for the past 20 years. The history of the horn's dates back much further. The Heritage Horns, as they are known at Canada Place, were built as a BC Hydro Canadian Centennial project in 1967 and were designed by engineer and sound specialist, Robert Swanson. For many years, they were positioned on the roof of the original BC Hydro Building where they sounded every high noon in the downtown core for more than 20 years.
