Canada's First Gay Prime Minister?

Did Canada already have its first gay Prime Minister? In Canada's capital, there's a romantic statue of Sir Galahad on Parliament Hill. It was created in 1905 by then future prime minister, William Lyon Mackenzie King, in memory of a heroic act by his dearest friend. Former Member of Parliament, Bill Siksay, the first openly gay man to be elected to Canada's parliament (but not the first openly gay MP), spills some historical Tea about the late prime minister and a very curious - and likely queer - statue.
