The Presbyterian congregation at L'Orignal was organized about 1822 by the Rev. John McLaurin, who visited L'Orignal as minister of the Church of Scotland for the Lochiel pastorate. In 1823 McLaurin became the teacher at the Ottawa District School in L'Orignal and conducted worship in the school or court house. He assumed official charge of the L'Orignal and Hawkesbury congregations in 1832. The present church was begun that year under his direction but for lack of funds was not finished until about 1836. The site for the church and manse was the gift of Charles Platt Treadwell, Seigneur of Pointe a L'Orignal. In 1825 the congregation of St. Andrew's joined The United Church of Canada.
