Evelyn Gregory was the Chief Librarian of York Township Public Library from its inception in 1945 to 1969. During her time with the library, she ran a main branch located on Eglinton Avenue, oversaw four additional branches, and started a bookmobile to support the borough. Her leadership was lauded, with local press noting that the bookmobile had an annual circulation in 1950 of 60,000. In 1959, Gregory reported to a Toronto Daily Star reporter that the library had four copies of Lolita, available upon request, and had no plans to remove it from circulation, although many local library systems had refused to carry the novel.
