There has been no record of this population since 1898. Human settlement was the most significant factor leading to the demise of the Lake Ontario population of Atlantic Salmon. Activities such as land clearing for timber and agriculture degraded and destroyed habitat by altering water levels and adversely impacting water quality through increased erosion and siltation. Further, the construction of mill and driving dams for the timber trade prohibited fish passage, and congregating fish at the base of the dams were overexploited by fishers. A short-lived commercial fishery also contributed to the loss of this population of Atlantic Salmon.
PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.

Consultation Workbook on the addition of the Atlantic Salmon (Lake Ontario population), Rainbow Mussel, Mapleleaf Mussel (Saskatchewan-Nelson population) and Mapleleaf Mussel (Great Lakes- Western St. Lawrence population) to the SARA List (2006)Your opinion is being sought to assist the government of Canada in making an informed decision on whether to add the Atlantic Salmon (Lake Ontario population), Rainbow Mussel, Mapleleaf Mussel (Saskatchewan-Nelson population), and Mapleleaf Mussel (Great Lakes-Western St. Lawrence population)) to the Schedule 1 (the List of Wildlife Species at Risk) of the Species at Risk Act (SARA). Your input on the impacts of adding these species to the List is important. This workbook has been developed to give you an opportunity to provide Fisheries and Oceans Canada with your feedback, advice, and other comments regarding adding these species to Schedule 1 of SARA (Schedule 1 identifies which species are legally protected under SARA).
