When the St. Lawrence Seaway project is opened to shipping, a type of ship, long familiar on the St. Lawrence River and in the Great Lakes, to all intents and purposes, will become obsolete. There are presently in existence about 180 Canadian registered St. Lawrence River canal vessels or "Canallers" as they are familiarly known from the Gulf of St. Lawrence to the Head of the Lakes, and the history and development of this type of ship are closely related to the development of Canada.

It is, therefore, appropriate on the eve of their relegation to a minor from a major role in Canadian shipping that a survey of these interesting vessels should be made. The specialized type of ship known as the "Canaller" is, of course, the result of the difficult geographical features of the St. Lawrence River and the limitations of the canals built to overcome these difficulties and the first part of this paper will deal with the development of these canals and the corresponding types of vessels leading to the emergence of the present day "full" Canaller.

The water route from the lakehead to the open sea is divided into three main parts; open water navigation on the lakes themselves, river and canal navigation on the upper St. Lawrence River between Kingston and Montreal, and almost unrestricted navigation on the lower St. Lawrence and the Gulf. The upper St. Lawrence section is, of course, the portion most closely associated with the canaller and the part which has restricted free navigation since Canada was first visited by Europeans.

When Jacques Cartier was exploring the St. Lawrence in 1535, he arrived on what is now the Island of Montreal after more than 1000 miles of fairly easy river navigation which, he believed, would eventually lead him to the middle of the then newly discovered continent. His hopes suffered a setback however, when he climbed Mount Royal and saw the Lachine Rapids blocking his path to the west.

These rapids are the first of a series between Montreal and Lake Ontario which have seriously hindered navigation ever since the days of Jacques Cartier and although a succession of canals has been built over the past 270 years the rapids will not be completely overcome until the Seaway is opened.

(Maps of the Great Lakes and St. Lawrence River, and the rapids and canals from Lake St. Francis to Lake St. Louis, are shown, respectively as Figs. 1 and 2.)
