Canadian Tigers could create a treaty battlecruiser category

How would history change if Canada acquired Tiger-class battlecruisers?

They would strengthen the wartime battlecruiser force and could produce a separate treaty category, though the United States would challenge the British Empire's apparent advantage.

Canadian Tiger-class battlecruisers would add fast capital ships to the British Empire's World War I force. Their continued existence alongside HMAS Australia could make battlecruisers a distinct problem at the Washington conference rather than an obsolete subset of battleships. A separate allowance might help bring the Netherlands and other smaller naval powers into the treaty structure. The United States would resist any arrangement that appeared to give the British Empire multiple additional capital-ship quotas.
