Our Story
The idea to begin a history room for the County began in 1974, when Mrs. Marion Ellwood (a librarian in Mandaumin) committed her Tuesday and Thursday mornings to the organization of a collection of “old pictures of buildings, streets and historic events". The Lambton Room as it was originally known, was housed in a small room in what was the old library headquarters building on Niagara Street in Wyoming (currently the Plympton-Wyoming municipal office.)

The collection continued to grow and in 1992 was moved to its present environmentally controlled location. In 2013, our name was updated to Lambton County Archives to better reflect the growth of the county's archival collection into a vibrant repository and research centre.
