Ontario Supports American Bid to Protect Great Lakes

McGuinty Government Taking Steps To Prevent Spread Of Asian Carp

Ministry of Natural Resources and Forestry

Ontario is supporting legal efforts by Michigan and other American states to prevent the spread of Asian carp into the Great Lakes. The move recognizes the significant economic threat these fish pose to the province's fisheries.

A legal brief from the Province has been filed with the United States Supreme Court supporting Michigan's motion for a preliminary injunction to close the locks in the Chicago Sanitary and Ship Canal. The closure is one of a number of measures sought by Michigan to keep this invasive species from passing into Lake Michigan.

Recreational and commercial fishing are vital to Ontario's economy, providing jobs and recreation for many Ontarians:

  • Approximately 1.4 million anglers fish in the province each year, spending more than $2.3 billion dollars annually on fisheries-related expenditures.
  • The commercial fishery in the Great Lakes is valued at about $200 million annually.
The U.S. Supreme Court will determine Ontario's participation in the proceedings.

Quick Facts

  • Biologists fear Asian carp could devastate fisheries in the Great Lakes.
  • Indiana, New York, Wisconsin, Ohio and Minnesota have all backed the Michigan action.
  • In some parts of Illinois, Asian carp now make up more than 90 per cent of the fish population.
  • In 2004, Ontario banned the buying and selling of live Asian carp.
