COOK, John, Canadian clergyman, born in San-quhar, Dumfries-shire, about 1810. He was educated at Edinburgh University, and received his theological training under Dr. Chahners; was ordained by the presbytery of Dumbarton in 1835, in the year following arrived in Quebec, and shortly afterward was appointed pastor of St. Andrew's church in that city. When the disruption took place in 1843, he retained his connection with the Established church of Scotland, and when the establishment of Queen's College, Kingston, was determined upon, he exerted himself to secure the necessary endowment, and has been a trustee of the institution ever since. In 1857 he assumed the presidency temporarily, and during two sessions acted as professor of divinity. The founding of Morin College, Quebec, was largly due to his efforts, and after its establishment he was the lecturer on divinity. In 1861 he proposed resolutions favoring a union between the free and the established branches of the Presbyterian church, and in 1875 such a union was effected, when Dr. Cook was moderator of the first general assembly.
