    Halibut Treaty

    The Halibut Treaty of 1923 (formally the Convention for the Preservation of Halibut Fishery of the Northern Pacific Ocean) was an agreement between Canada and the United States on fishing rights in the Pacific Ocean. It was the first environmental treaty aimed at conserving an ocean fish stock. It was also the first treaty independently negotiated and signed by the Canadian government; one of several landmark events that transitioned Canada into an autonomous sovereign state. It also indicated a shift in Canada’s economic focus from Britain to the US during the 1920s, when the US passed Britain as Canada’s largest trading partner. The treaty created the International Pacific Halibut Commission, which continues in its role today.
