Surely Justin Trudeau knows about the unofficial 10-year rule: The one that says Canadians allow prime ministers a decade or thereabouts at the helm, before they want change. The latest example was Stephen Harper, who tried to extend his stay in 2015, only to be sidelined by Mr. Trudeau.
A 10-year time frame is fair. It is a lot of time – more than enough, actually. It gives a leader ample opportunity to put his or her priorities in place. Then fatigue tends to set in and the time-for-change chorus grows.
