Appointment to the Order of Canada is the process by which citizens of Canada or certain foreign persons are inducted into the Order of Canada, the second-highest civilian honour within the Canadian system of honours. Any living Canadian or foreign national may be nominated for appointment; however, the advisory council of the Order of Canada and the Governor General of Canada make the final decision on appointments. Recipients of the order may also be promoted to a higher grade within it if they have continued to provide outstanding service to Canada, or to humanity in general, after their appointment. Eligibility Paragraph nine of the Constitution of the Order of Canada lists the criteria for appointment to the order. All living Canadians are eligible for any of the three levels of the order, except federal and provincial politicians and judges while they are holding office. Multiple people who have committed the same honourable act or deed are also eligible for induction; for example, all three members of the band Rush (Geddy Lee, Alex Lifeson, and Neil Peart) have been appointed as Officers of the order, the first time a group, rather than an individual, was appointed to the Order of Canada. All three members of the children's group Sharon, Lois & Bram (Sharon Trostin Hampson, Lois Lilienstein, and Bramwell Morrison) have also been made members of the order – although, since Lilienstein is an American citizen, she was made an honorary member. A new member whose appointment is approved during their lifetime but who dies prior to either the announcement of that appointment or their investiture, may be invested posthumously. The 2005 appointment of journalist Peter Jennings was announced under these circumstances; his daughter, Elizabeth Jennings, accepted the insignia on her father's behalf in October, 2006. The oldest person ever to be invested into the order was Cornelius Wiebe, who was 106 years old at the time of his investiture in 1999. Commonly, influential political leaders, such as former prime ministers, are appointed after they retire from politics. John Diefenbaker was the only living former prime minister not to be appointed to the Order of Canada; after losing the prime ministership to Lester B. Pearson in 1963, Diefenbaker remained a sitting member of parliament and died while still in office in 1979, never becoming eligible. Others, such as former New Democratic Party leader Ed Broadbent and former Prime Minister Joe Clark,
