She was born on December 10, 1858, in La Prairie, Quebec, a small town on the south shore of the St. Lawrence River near Montreal. She was christened Margaret Anne but later changed her second name to Ridley, to honour her descent from the family of the martyred Bishop Nicholas Ridley, who was burnt at the stake in Oxford in 1555.
Career
The McGill University Medical Library was founded on August 27, 1823. It was part of the university's Faculty of Medicine and, as was common practice in the 19th and early 20th centuries, a faculty member held the title of "Librarian". Charlton, who had recently completed a summer course at Amherst College in the newly developed field of librarianship, and is thought to have studied under Melvil Dewey, came to this library in 1895. She was appointed to be the library's first Assistant Librarian in 1896. She remained at the McGill Medical Library in this position until 1914, when she resigned under less than happy circumstances, and moved to Toronto as Librarian of the Academy of Medicine. Charlton was probably the first person with any formal library training to work at McGill University. Her interest in wider library issues was demonstrated shortly after she arrived, as she was reimbursed $55 for the expense of attending a meeting of the American Library Association in Chicago in 1896. The following year, the British and Canadian medical associations held a joint meeting in Montreal, and it was probably here that Charlton first met prominent Canadian physician William Osler. Osler had graduated from McGill in 1872, and after postgraduate studies in Europe he had returned as a faculty member. He left McGill in 1884 to go to the University of Pennsylvania and by 1897 was at Johns Hopkins University in Baltimore. Osler was always interested in, and supportive of, libraries and had served on the Faculty's Library Committee while at McGill. He was almost certainly eager to meet the newly appointed assistant librarian of his alma mater. It was most likely due to this 1897 meeting that William Osler and Margaret Charlton became involved in the formation of the Association of Medical Librarians, founded on May 2, 1898, by four librarians and four physicians who met in the office of the Philadelphia Medical Journal, at the invitation of its editor, George M. Gould, M.D. The object of the Association was the fostering of medical libraries and the maintenance of an exchange of medical literature among its members. Membership was limited to librarians representing medical libraries of at least 500 volumes, with regular library hours and attendance. Miss Charlton served as the Association's first Secretary from 1898–1903 and again from 1909–1911, after it had become the Medical Library Association. One of the other founding members, Marcia Crocker Noyes, writes of Margaret Charlton as follows: In November 2000, Charlton was proposed to the Historic Sites and Monuments Board of Canada as a "person of national historic significance". This board, created in 1919, is responsible for making such recommendations to the Canadian government, and in late 2002 it supported the proposal. In September 2003 the Minister of Canadian Heritage, Sheila Copps, approved the Board's recommendation, and Charlton has been added to the list of approximately 600 other "persons of national historic significance". In 2006 a Government of Canada plaque honouring her accomplishments was unveiled at the McGill University Life Sciences Library and this was erected outside the in November 2012 where it is close proximity to similar plaques to her contemporaries William Osler and Maude Abbott.

Later life
In 1922 she left the Academy of Medicine, also under less than happy circumstances, and returned to Montreal to live with her sisters. She died there on May 1, 1931, and is buried, with her mother and two of her three sisters, in Mount Royal Cemetery.
