E. L. Ruddy & Co

E. L. Ruddy & Co was a Canadian outdoor advertising company founded by Ernest L. Ruddy that operated from 1904 to 1973. It was initially known as the Connor-Ruddy Company and later merged into Mediacom and later CBS Outdoor Canada.

In its early years the company made wood signs, but evolved into neon signs after the Second World War, primarily large ones, for major corporations and large retail operations across Canada.
