History & History Related Items

Ontario was founded June 11, 1883 by William Morfitt, James W. Virtue, Daniel Smith and Mary Richardson. They chose the site because they knew the railroad was coming through the area and felt it would be a great investment. Naming the town proved to be difficult. Mr. Morfitt wanted to name it for his daughter, Ione. Mr. Virtue wanted to name it after his home in Canada. Some say a coin was flipped and others say it was drawn out of a hat, But, in the end, Ontario won out. It was incorporated in 1896.
