Keswick's first public library was founded in the 1960s, and housed in the Optimist International Hall before being moved to a former post office building beside the fire fighters and police stations.

In 1996, the Sutton branch was incorporated into a new shared facility with York Region's public and separate school boards on Black River Road.

Keswick's branch moved to a shared facility in the Georgina Ice Palace on Wexford Drive and Woodbine Avenue in 2002.

The library is growing to meet the demands of a developing community as Georgina becomes increasingly part of the expansive Greater Toronto Area.

The material collection includes fiction and non-fiction books for kids, teens, and adults, DVD's, audiobooks, e-books, magazines, newspapers, and video games.
