History
Arnprior was established around the timber industry in 1851, at the confluence of the Madawaska River and the Ottawa River in the Ottawa Valley. It was incorporated as a village in 1862 and as a town in 1892.
The town's location at the meeting of two rivers made it a natural centre for the lumber trade through the 19th and early 20th centuries, shaping its historic downtown along John Street.
Arnprior's first cinema opened on the site of the current O'Brien Theatre in 1906; the present building dates from 1919 and originally hosted both films and vaudeville performances, becoming a full-time cinema in 1929. It was restored to its 1930s appearance in 2000, with a second screen added upstairs.
Arnprior has continued to grow as a separate town within Renfrew County, with its 2021 census population of 9,629 representing a 9.5% increase since 2016.
