Canada Shipbuilders and Boatbuilders
Although there are 131 Canadian shipbuilders and boatbuilders documented in these pages, there are many more that were too small to make it. Some of these may deserve inclusion and will make it eventually. Note that the use of "closed" and "suspended" in the "Notes" column of these pages: these terms simply mean that a vessel is no longer in the Canadian Registry: it may have been lost or scrapped and no longer exists, but it could have been laid up or transferred to another flag. Most of these tables have gaps in them.
