William Finlayson (December 12, 1874 November 14, 1943) was an Ontario lawyer, cabinet minister and political figure. Early life Born in Brantford, Ontario, he was the son of Alexander F. Finlayson and Annie Tupper, and was educated at Jarvis Collegiate Institute and Osgoode Hall Law School in Toronto, Ontario. He set up practice in Midland in 1897 in partnership with William Humphrey Bennett. In 1905, he married Ethel Cora Sinclair. He was President of the Simcoe Railway and Power Company, which constructed the Big Chute hydroelectric plant in 1909. The plant was acquired by the Hydro-Electric Power Commission of Ontario in 1914, being the first station owned and operated by it. Finlayson served in the Canadian Militia, eventually becoming a captain in the 35th Simcoe Foresters. During World War I, Finlayson enlisted in the 157th Battalion of the Canadian Expeditionary Force, and served in France as a captain in the 10th Brigade, Canadian Field Artillery. Finlayson entered into a law practice in a partnership with George Dudley in 1917. They established at Finlayson & Dudley, Barristers and Solicitors at 212 King Street in Midland. Dudley took over the firm upon Finlayson's death. Political career Finlayson was mayor of Midland, Ontario from 1906 to 1907. He represented Simcoe East in the Legislative Assembly of Ontario from 1923 to 1934 and from 1937 to 1939 as a member of the Progressive Conservative Party of Ontario. in 1926, Finlayson became the Minister of Lands and Forests in the government of Howard Ferguson, which he would continue to hold until 1934. Prior to his appointment, Ernest H. Finlayson (his half-brother and the head of the Dominion Forest Service since 1925) gave him an intensive crash-course in silviculture, which "resulted in... [Minister Finlayson]... stepping into the job with, perhaps, a greater knowledge of the principles of forestry than has probably been the case with any other non-technical man who has occupied a Cabinet post." In 1927, Finlayson declared to the Legislature: As Minister, he was responsible for the passage of several Acts relating to forestry in Ontario (although their effectiveness has since been questioned): The Forestry Act, 1927 (which provided for the expropriation of lands for forestry purposes, and for the moving of inhabitants of barren lands (such as the Trent watershed) to other agricultural areas, including the Great Clay Belt) The Provincial Forests Act, 1929 (which created provincial Forest Reserves) The Pulpwood Conservation Act,
