The 1970s saw significant change for Vaughan, with the amalgamation of various communities within York County. In 1971, the Township of Vaughan became the Town of Vaughan, with the Village of Woodbridge being incorporated into the latter. The Regional Municipality of York was also created during this time, replacing the former York County. With the creation of a Regional Government administration, the Police Village of Thornhill ceased to exist, and management of the community reverted to the newly created Towns of Markham and Vaughan.
