Built in Lauzon, Quebec by Davie Shipbuilding, this large tug was delivered to the Government of Canada in 1962 as the W.N. Twolan. The government operated the Twolan out of Churchill, Manitoba until 1986, when McKeil Marine acquired the tug and began using her on the Great Lakes. Buchanan Forest Products bought the Twolan from McKeil in 1995 and paired her with the lumber barge McAllister 132. Operations for Buchanan ended in 2008, and the tug and barge were laid up in Thunder Bay. In 2011, she was chartered out to Les Grains Lac Superior Ltee. and placed back in service handling grain barges, mostly on the Seaway, and laying up in Toronto when not needed.
The W.N. Twolan last operated in 2012 and has been laid up in Toronto ever since.
