The M.S. "Normac" began her scheduled route on July 16, 1931, taking the place formerly assigned to the S.S. "Manasoo", leaving Owen Sound at 11:15 p.m. Thursdays and returning at 4:30 am on the following Tuesday. Meanwhile, with the S.S. "Manitoulin" continuing her weekly Monday evening departures from Owen Sound, the OSTC also acquired the service of the Georgian Bay and Manitoulin Transportation Company and its steamer the S.S. "Henry Pedwell", which they renamed S.S. "Kagawong". The "Kagawong" was returned to the Tobermory - South Baymouth auto ferry route during the 1931 July to September season. During early and late seasons she operated on the Sault Ste. Marie route from Tuesday evening to Saturday morning, with weekend trips to Providence Bay.
