The Government of Ontario (French: Gouvernement de l'Ontario), formally Her Majesty's Government of Ontario, is the body responsible for the administration of the Canadian province of Ontario. A constitutional monarchy, the Crown—represented in the province by the lieutenant governor—is the corporation sole, assuming distinct roles: the executive, as the Crown-in-Council; the legislature, as the Crown-in-Parliament; and the courts, as the Crown-on-the-Bench. The functions of the government are exercised on behalf of three institutions—the Executive Council; the Provincial Parliament (Legislative Assembly); and the judiciary, respectively. Its powers and structure are partly set out in the Constitution Act, 1867.
The term Government of Ontario (French: Gouvernement de l'Ontario) refers specifically to the executive—political ministers of the Crown (the Cabinet/Executive Council), appointed on the advice of the premier, and the non-partisan Ontario Public Service (whom the Executive Council directs), who staff ministries and agencies to deliver government policies, programs, and services—which corporately brands itself as the Government of Ontario, or more formally, Her Majesty's Government of Ontario (French: Gouvernement de l’Ontario de Sa Majesté).Owing to the location of the Ontario Legislative Building on the grounds of Queen's Park, the Ontario government is frequently referred to by the metonym "Queen's Park".
