The Claireville Conservation Area, one of the largest tracts of land owned by the Toronto and Region Conservation Authority (TRCA), is unique. It was acquired in 1957 to construct a flood control dam and reservoir after the destruction caused by Hurricane Hazel. The park is a 848 hectare (2,100 acre) parcel of conservation land located on the west branch of the Humber River in Brampton, Ontario, Canada. Claireville contains significant natural and cultural heritage features, and has outstanding recreation, tourism and educational facilities and programs.
The Etobicoke Field Studies Centre is located in the southern corner of Claireville and provides programs for student from Grade 1 to Grade 6. Located in the northern corner of the park is the Claireville Ranch, it provides horse riding lessons, trail riding and other group activities. The Indian Line Campground is located at the southern tip of the park, in the Regional Municipality of Peel. It offers 245 serviced and unserviced campsites.
The landscape of the park is diverse. Its characteristic features are numerous creeks and ravines, flat plains, and rolling hills enriching the forested landscape. The TRCA has declared an early 20th-century farmhouse in the northern part of Claireville as a heritage property; major restoration began in 2005. The park is home to the Eastern Coyote, Wood Duck, Chimney Crayfish, Deer, Muskrat, and Common Garter Snake. The park's varied landscape can be admired from many vantage points. In 2003 the HSBC BANK donated the funds to plant the HSBC Forest at the Claireville Conservation Area. The park is a favorite with local dog owners, bird watchers and wildlife photographers.
