World Heritage sites are areas designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO), with the goal of preserving places of cultural, natural and historic significance. There are 22 World Heritage sites in Canada.
Background
A convention concerning the protection of the world's cultural and natural heritage was launched by United Nations Educational Scientific and Cultural Organization (UNESCO) in 1972. It aimed to recognize and protect sites around the world with universal natural or cultural significance. Designations require the co-operation of participating countries. Nearly 200 states have signed the convention, agreeing to protect designated properties within their boundaries and to contribute to the World Heritage Fund, which was established to help preserve endangered sites. World Heritage sites are selected by a committee according to established criteria.
