Old Newmarket Town Hall and Courthouse, Heritage courthouse and town hall in Newmarket, Canada

The Old Newmarket Town Hall and Courthouse is a courthouse and town hall in Newmarket, Canada. The building features brick walls with Italianate architectural details and occupies a prominent location on Botsford Street in the downtown core.

The building was inaugurated on Dominion Day, July 1, 1883, as Newmarket's town hall, designed in the Italianate style by Mallory & Sons under Mayor William Cane. It housed York County offices from 1953, when they moved from Toronto City Hall, until York Region was formed in 1971. Town offices left in 1975, and from 1975 to 1980 it served as the municipal courthouse while a new one was built at 50 Eagle Street.

The building now serves as a cultural venue where theater productions, art shows, and music events take place regularly. The spaces bring together residents for performances and community celebrations throughout the year.

The building stands on Botsford Street in downtown Newmarket, with the main entrance giving access to the former council rooms and the second-floor theatre. Renovations completed after 2012 made the whole building fully accessible, adding an elevator and an atrium extension on the south side. The theatre, meeting rooms and cultural spaces host performances and community events.

A glass atrium extension connects the original building to contemporary spaces while respecting its initial character. This blend of historical and modern elements shows how the site has adapted to serve new purposes.
