A number of streets in Ottawa's Centretown that were on land originally owned by members of the Stewart family, south of the built up area of the city are, or were named for his family members. Catherine street was named for his wife, Catherine Stewart. James and McLeod Streets for his sons, and Flora, Isabella, Florence, and Ann streets were named for his daughters. Ann street was later renamed Gladstone for the British Prime Minister. Stewart street in Sandy Hill was not named for him, as that name predates him.
