Answer 2

"Canada’s fleet of wooden vessels began to disintegrate during the 1800's with the advent of the steel ship. A long quiet period followed until Canada once again became a major player on the high seas when World War I necessitated the urgent construction in Canada of a proud new fleet. These WWI-built vessels operated during the 1920's, but with the Great Depression of the thirties and extremely low freight rates, they too were abandoned. After another brief period of inactivity, the outbreak of World War II in 1939 precipitated the building of a vast new Canadian fleet of steel deep sea ships. With this merchant fleet, all under Canadian Flag, Canada was once again a major international shipping power. By 1946 our nation had some 785 deep-sea cargo vessels on its register. Between 1946 and 1966, there was a gradual disappearance of these ships from the Canadian register. Since about 1970, Canada has been without its own ocean-going merchant fleet and we have depended on vessels flying the flags of other nations for the carriage of our international import and export trade."
