There's always something to do at Centennial Park, one of Toronto's busiest parks. Located at the northwest corner of Toronto, this park is home to the Etobicoke Olympium, Centennial Park Ski hill and Chalet, Centennial Arena, Centennial Park Conservatory, Centennial Park Stadium and a new BMX bike park. The park also has a number of playgrounds, sport fields, baseball and softball diamonds, picnic areas and a wading pool. Centennial was opened in 1967 to celebrate Canada's 100th birthday. The land the park now occupies was once a dairy farm. A large portion of this farm was purchased by the City of Toronto to create the park. The ski hill now sits atop what was once a municipal dump. It was closed and covered over to provide users with an intermediate ski slope, a beginner slope and a snowboard slope. Centennial Park and the Etobicoke Olympian were two of the major sporting venues for the 2015 Pan Am Games.
