In an effort to keep British possessions in the Caribbean loyal to the mother country rather than the much-closer United States, Canada agreed to offer steamship service to the West Indies. This was farmed out to Canadian National just about as soon as the railway was created in 1919. For a time CN also had ships from Canada to Australia, but these lost so much money that those routes were abandoned.

In addition to merchant marine, CN offered cruises to the West Indies. This booklet generally describes 11 of the most important Caribbean ports reached by CN ships from Halifax (in winter) or Montreal (in summer). The booklet is nicely decorated with some pages printed in red and silver and others in blue and gold.
