<human>: Upon his return to England Carleton recommended the creation of a position of Governor General of all the provinces in British North America. Instead he was appointed "Governor-in-chief", with simultaneous appointments as governor of Quebec, New Brunswick, Nova Scotia, and St. John's Island (present-day Prince Edward Island). He arrived in Quebec on 23 October 1786. His position as Governor-in-chief was mostly ignored. He found quickly that his authority in any of the provinces other than Quebec was effective only while he was present in person.  He was raised to the Peerage in August 1786 as Lord Dorchester, Baron of Dorchester in the County of Oxford.  The Constitutional Act of 1791 split the large territory of Quebec into Upper and Lower Canada, corresponding roughly to areas settled by ethnic British and ethnic French, respectively. Sir Alured Clarke was named as the lieutenant governor of Lower Canada and John Graves Simcoe the lieutenant governor of Upper Canada. In August 1791 Carleton left for Britain and on 7 February 1792 took his seat in the House of Lords. He left for Canada again on 18 August 1793 to resume his duties there. His replacement, Robert Prescott, arrived in May 1796. On 9 July 1796 Carleton sailed from Canada to Britain, never to return.  In retirement Carleton lived mostly at Greywell Hill, adjoining Nately Scures, in Hampshire. After about 1805 he moved to Stubbings House at Burchett's Green, near Maidenhead, in Berkshire. On 10 November 1808, he died suddenly at Stubbings. He was buried in the parish church of St Swithun's, Nately Scures. CANNOTANSWER
