Originally native to Ontario, the Trumpeter swan’s extirpation from eastern Canada over 200 years ago was primarily due to hunting pressure and habitat loss.
Biologist Harry Lumsden began a provincial reintroduction program in the early 1980’s to re-establish the Trumpeter swan in its former habitat and range.
