Mill No. 4 was built in 1892, just 300 yards East of Mill No. 3 on the shore of the Ottawa River. Like Mill No. 3, it was steam-operated and equipped with the latest technology of its day. Mill No. 4 had a a 125-foot high "Iron Bottle" burner. It was the last mill built by the McLachlin Bros. Due to an economic downturn in the 1920s, only Mills 3 and 4 were still in operation by 1923. They ceased operation in 1929, and Mill No. 4 was finally demolished in 1936.
