Is actually turning in to a bit of a campaign. There is a
http://www.facebook.com/pages/Help-nominate-William-Shatner-for-Governor-General-of-Canada/102216946483989?ref=ts&v=info">Facebook thingy with more than 10k people signed up. Although the creator of the page lists some reasons of his own, including how much fun it would be (just imagine the speech from the throne - Kirk style) here are my top 10 reasons:
1) He would instantly be the best known Canadian statesman internationally, at the very least since Trudeau - but in many places he would be better known than Pierre ever was.
2) From his start at the Stratford Festival Shatners career in stage, screen and television has spanned 6 decades so far. He is probably the best known Canadian actor and the best known Canadian pop culture figure of the 20th century.
3) In addition to his acting career he's written over 20 books, fiction and non fiction and even released a few albums further strengthening his arts and culture credentials and having done podcasts he even has some grasp of the internet.
4) I haven't heard many political statements from him (except in character as Denny Crane) but from what I have heard he strikes me as non-partisan, well informed and reasonable.
5) He would be a great ambassador not only for Canada but for Canadian arts and culture.
6) Although he has spent much of his career working in the United States he has always been proudly and vocally Canadian when the topic came up.
7) Foreign leaders would line up for Canadian visits and Canadian embassy events if only so they could meet Captain Kirk
8) As an actor William Shatner could pretend those foreign dignitaries were interesting
9) With his own cult following and Hollywood connections he could fund raise for charity like no GG before him
10) He has a sense of humor, which can't hurt given the job description
