The Order of Ontario () is a civilian honour for merit in the Canadian province of Ontario. Instituted in 1986 by Lieutenant Governor Lincoln Alexander, on the advice of the Cabinet under Premier David Peterson, the civilian order is administered by the Lieutenant Governor-in-Council and is intended to honour current or former Ontario residents for conspicuous achievements in any field.

Structure and appointment

The Order of Ontario is intended to honour any current or former longtime resident of Ontario who has demonstrated a high level of individual excellence and achievement in any field, demonstrating "the best of Ontario's caring and diverse society and [whose] lives have benefited society in Ontario and elsewhere." Canadian citizenship is not a requirement Since appointments to the Order of Ontario rely in part on ministerial advice, records of such proceedings are not publicly revealed, as affirmed in court proceedings undertaken in 2002 by an individual who had been mistakenly informed that she had been appointed to the order. The name of the member is engraved on the reverse, along with the date of their investiture.
