Prince Charles Declared King Charles the Third

Summary#

This is the federal proclamation Proclamation Proclaiming that His Royal Highness Prince Charles Philip Arthur George Is Now, by the Death of Our Late Sovereign, King Charles the Third (SI/2022-42). It formally records that Prince Charles Philip Arthur George is now King Charles the Third. The proclamation was registered on September 10, 2022 and published in the Canada Gazette, Part II on September 14, 2022.

What it does#

• Announces the accession of Prince Charles Philip Arthur George to the throne and names him King Charles the Third.
• Publishes that announcement in the Canada Gazette so there is an official, public record of the succession.
• The notice itself does not list any new policies or changes beyond declaring the new sovereign.

Who's affected#

• All Canadians, broadly, because the identity of the sovereign is a constitutional fact for Canada.
• Organizations and public bodies that refer to the Crown (for example, governments, courts, schools, and places that use royal symbols) are the most likely to notice and act on the change.
• The proclamation text does not list specific groups or actions required.

Why it matters#

• It is the formal public step that confirms who is Canada’s monarch after the death of the previous sovereign.
• Where official documents, oaths, seals or other items name the monarch, authorities and organizations may need to update wording or symbols over time — though this proclamation itself does not set out those follow-up changes.
