cormorant drying its wingsThe Toronto Regional Conservation Authority is currently investigating management options for the Double Crested Cormorant colony at Tommy Thompson Park (more commonly known as the Leslie St Spit).

The Black Crested Cormorant population in Ontario was originally documented in the early twentieth century; however, this bird easily succumbed to the increasing industrial pollution in the great lakes, and was devastated by DDT use until its ban allowed the birds to recover. It is unfortunate that instead of celebrating the recovery of this species as a success, now that they are abundant, they are considered to be pests.

Management techniques currently being considered are: do nothing, deterrence, habitat improvements and egg oiling.

The Humane Society of Canada participated in the public meetings held in early April, 2008 in the eastend of Toronto. To read our submission, please click here.
