The first settlement was created in 1800 across from Ottawa in Hull by a New Englander named ‘Philemon Wright’. The community, called Wrightsville, became a pioneer in the Ottawa Valley timber trade. Bytown (later Ottawa) was founded in 1826 due to work being done on the Rideau Canal. Barracks and a town were set up, and the population reached 1,000 as the Canal was being finished in 1832. It was renamed Ottawa in 1855 and incorporated as a city.
