The Mute Swan is native to Eurasia, but was introduced to North America beginning in the late 1880s. It was first reported in Canada in the mid-1900s, with breeding confirmed in Ontario in 1958. Numbers have increased ever since, to at least 5,500 individuals that are year-round residents, primarily along the northern shores of Lake Erie and Lake Ontario, and in southern British Columbia. This represents slightly over 1% of the global population. There is very high confidence that the population has undergone a large increase based on agreement between the Breeding Bird Survey and the Christmas Bird Count. There is no population goal for Mute Swan, as goals are not set for introduced species.
