If the Royal Canadian Navy received four Renown-class battlecruisers, would it retain them into the Second World War?
Short answerThere is no single outcome. Retention, sale back to Britain and treaty disposal would depend on Canadian funding choices and the terms negotiated at Washington.
NotesThe first difficulty is timing, since the Renown class was ordered only after the First World War began. Assuming four Canadian ships were delivered and in service, their cost would make their disposal a substantial political decision. Canada could retain them or sell them back to Britain, with the Washington Naval Treaty affecting the available choices. The answer remains conditional on what Canadian governments would pay for and what negotiators would accept.
