Born at L’Assomption, Quebec, on March 21, 1810, Joseph Aumond arrived in Bytown (Ottawa) at the age of 18. In the 1830s he entered the timber trade and acquired a large number of properties and buildings. He became a prosperous merchant and made his fortune in the timber trade along the Ottawa River, where he employed up to 1,000 men. Known as Big Jos or Colonel, Aumond was a lieutenant in the first regular Bytown Fire Company in 1838, and a lieutenant-colonel in the 4th Batallion, Carleton Militia. In 1842, he was one of the first members of the board of school trustees, and in 1847 he was appointed to the original Board of Health. Joseph Aumond was successively president of the Bytown and Montreal Telegraph Company (1849), founding member and director of the Bytown and Prescott Railway (1850), and a director of Consumers Gas (1854) and of the City Passenger Horse Railway (1866). He ran as a Conservative in the 1874 federal election but was defeated. Joseph Aumond, one of the leading citizens of his time, and his wife Jane Cumming were active supporters of the community of Grey Nuns (Sisters of Charity), which was established in Bytown in 1845. Aumond died in Ottawa on November 9, 1879.
