Confederation of Canada in the context of George Frederic Matthew

The following is a list of lieutenant governors of Ontario and the lieutenant governors of the former colony of Upper Canada. The office of Lieutenant Governor of Ontario was created in 1867, when the Province of Ontario was created upon Confederation. The predecessor office, lieutenant governor of Upper Canada, was a British colonial officer, appointed by the British government to administer the government of the colony, from 1791 to 1841. (Prior to 1791, the territory which is now Ontario was part of the old Province of Quebec, which was administered by the colonial governors of the Province of Quebec.)

In 1841, the two provinces of Upper Canada and Lower Canada were abolished and merged into the new Province of Canada, with a single Parliament and Governor General. Upper Canada was known as Canada West, but did not have a separate government or lieutenant governor. It was simply an administrative division of the Province of Canada.

The Anglican Diocese of Newfoundland was, from its creation in 1839 until 1879, the Diocese of Newfoundland and Bermuda, with the Cathedral of St. John the Baptist at St. John's, Newfoundland, and a chapel-of-ease named Trinity Church in the City of Hamilton in Pembroke Parish, Bermuda (not to be confused either with the Parish church for Pembroke Parish, St. John's, or with Holy Trinity Church, the parish church of Hamilton Parish).

Newfoundland and Bermuda had both been parts of British North America until they were left out of the 1867 Confederation of Canada. In 1842, her jurisdiction was described as "Newfoundland, the Bermudas". In 1879 the Church of England in the British Overseas Territory of Bermuda (since 1978, an extra-provincial diocese of the archbishop of Canterbury re-titled the Anglican Church of Bermuda) was created, but continued to be grouped with the Diocese of Newfoundland under the bishop of Newfoundland and Bermuda until 1919, when Newfoundland and Bermuda each received its own bishop.
