From the CBC obituary:

"During an April 2008 visit at his home from Canadian Veterans Affairs Minister Greg Thompson, Babcock mentioned that he'd like to get his Canadian citizenship back. Thompson encouraged him to contact Prime Minister Stephen Harper.

Babcock did so immediately, writing a note on the nearest sheet of paper, which happened to be decorated with pictures of American flags and teddy bears, according to a Canwest News report. "Dear PM," the note said, according to the report. "Could I have my citizenship restored? I would appreciate your help. Thank you, John Babcock."

Thompson presented the note to Harper at a cabinet meeting, and Gov. Gen. Michaëlle Jean agreed to grant Babcock his citizenship. Canadian officials flew to Babcock's home for an official swearing-in ceremony.

"We are proud to welcome Mr. Babcock back into the Canadian family and to honour the service he gave our country," Harper said in a release at the time. "He symbolizes a generation of Canadians who, in many ways, were the authors of modern Canadian nationhood.""

He gave service to both Canada and the United States. What a guy.
