The position of Secretary of State for Canada was a Canadian Cabinet position with a corresponding department. It was established in 1867 as the official channel of communication between the Dominion of Canada and the Imperial government in London. As Canada became increasingly independent after World War I and particularly with the passage of the Statute of Westminster in 1931 this role fell into disuse. The department was maintained, however, and was used to administer various aspects of government which did not have their own ministry. As well, the Secretary of State for Canada was Registrar-General responsible for the Great Seal of Canada and various functions of state associated with it.
