Governor General Mary Simon will formally announce the queen’s death and the accession of a new sovereign in a proclamation to be published in the Canada Gazette, the government’s official newspaper, Nathan Tidridge said. He wrote a background on the death of the reigning monarch for the Institute for the Study of the Crown in Canada. Charles automatically became King of Canada after the death of Queen Elizabeth. But the declaration of accession is issued by the Governor General on the advice of the federal office of the Privacy Council, according to the book Canada’s Deep Crown, co-authored by David E. Smith, Christopher McCreery and Jonathan Shanks. The ceremony will begin at 10 am. ET. In the UK, the Queen’s death will trigger 12 days of official national mourning. Canada, however, is unlikely to officially mourn for the same length of time. Much of how Canada marks the Queen’s death will depend on the current government. At some point, according to the Government of Canada Official Procedure Manual, the government will issue a statement about the period of official mourning. The House of Commons adjourns for the summer and is not scheduled to reconvene until September 19. However, protocol states that the prime minister should reconvene Parliament and proceed with a joint speech of faith and support and any messages of condolence. The Prime Minister will also see to the secondment of the proposals by the Leader of the Opposition.
