The MacLaren Art Centre is the regional public art gallery serving the residents of Barrie, the County of Simcoe and the surrounding area. The Gallery has a permanent collection of contemporary Canadian art held in trust for the public and presents a year-round programme of world-class exhibitions, education activities and special events.

The MacLaren is housed in an award-winning building in downtown Barrie. This architectural landmark combines a renovated 1917 Carnegie library with a contemporary addition designed by Siamak Hariri of Hariri Pontarini Architects. The City of Barrie owns the building in which the MacLaren Art Centre operates. The complex includes multiple galleries, an education centre, a sculpture courtyard, café and gift shop. Admission is by voluntary donation. The building is wheelchair accessible. Adjacent parking is available.
