McLaughlin served as honorary colonel until 1967, thereby becoming the longest continuously-serving colonel in the history of the Canadian Forces. In 1967, McLaughlin was appointed a Companion of the Order of Canada. Philanthropy In 1951, he established the McLaughlin Foundation which, from 1953 to 2003, donated nearly $200 million to the University of Toronto and other causes, including the McLaughlin Planetarium at the Royal Ontario Museum. McLaughlin was a major contributor to Queen's University at Kingston, Ontario. The university's Mechanical Engineering Department is housed in McLaughlin Hall, which was his donation in 1948. McLaughlin Hall in Queen's University's John Deutsch University Centre is also named for him. His wife, Adelaide McLaughlin, was honoured in 1957 by Queen's, which named the women's residence Adelaide Hall for her. In 1947 McLaughlin and his wife donated land for a Boy Scout camp on the outskirts of Oshawa. The camp was named "Camp Samac". McLaughlin donated $1 million to the 1968 library building at the University of Guelph, which bears his name. He provided partial funding to build a college at York University in Toronto. Opened in 1968, it was named McLaughlin College in his honour. McLaughlin Hall at St. Andrew's College in Aurora, Ontario, which he unveiled in 1971 at age 99, is named after him in recognition of his contributions to the school. He endowed the Regimental Foundation of The Ontario Regiment (RCAC) and quietly paid the salaries of some of the regiment's soldiers during times of severely curtailed government funding. McLaughlin House at the Lester B. Pearson United World College of the Pacific also bears his name. He gave generously to the art community. Among other gifts, he gave Lawren Harris`s Pic Island, Arthur Lismer`s Bright Land, and Emily Carr`s Old Tree at Dusk to the McMichael Canadian Art Collection in Kleinburg.
