The William Rest is a tugboat built for the Toronto Harbour Commission in 1961 for $150,000 CAD. She was built in Erieau, Ontario by the Erieau Shipbuilding and Drydock Limited. She displaces 61 gross tons. She was named after the commission's recently deceased director of planning. Rest had worked for the Commission for 46 years.
She is powered by a Caterpillar 379D which can supply 560 horsepower (420 kW).
In 1975 the tugs William Rest, the Lac Como, the G.W. Rogers and the Bagotville tried to free the lake freighter George M. Carl.
The Toronto Harbour Commission occasionally employs the William Rest to break ice on the lower Don River.
Port authorities retired the William Rest when they commissioned its replacement, the Iron Guppy, in the summer of 2016.
