Over the years, a number of prominent Canadians became members of the Privy Council of the United Kingdom and thus were entitled to use the style Right Honourable, either because of their services in Britain (e.g. serving as envoys to London) or as members of the Imperial War Cabinet, or due to their prominence in the Canadian Cabinet. These included all but three of Canada's early prime ministers (Alexander Mackenzie, John Abbott, and Mackenzie Bowell), who governed before the title was used domestically.
