Early life and the Queen’s Rangers
Simcoe was the son of Captain John Simcoe, a naval officer who died on the Quebec expedition of 1759, and Katherine Stamford. After his father’s death the family moved to his mother’s home in Exeter. He attended Exeter Grammar School and Eton College, spent a year at Merton College, Oxford, and was admitted to Lincoln’s Inn. In 1770 he became an ensign in the 35th Foot.
His regiment reached Boston in 1775, two days after the battle of Bunker Hill. Simcoe later bought a captaincy in the 40th Foot and was wounded three times during the American Revolutionary War, the first and most serious time at Brandywine. On October 15, 1777, he took command of the Queen’s Rangers, a loyalist corps, with the provincial rank of major. He was captured in an ambush in 1779 and held for six months, and in 1781 he was invalided home shortly before the surrender at Yorktown. His account of the corps, the Journal of the operations of the Queen’s Rangers, was published at Exeter in 1787.
On December 30, 1782, he married Elizabeth Posthuma Gwillim. They had 11 children. A separate article covers Elizabeth Simcoe and her diary of the Upper Canada years.
Appointment to Upper Canada
Simcoe was elected to the House of Commons for St Mawes, Cornwall, in 1790. His commission as lieutenant governor of Upper Canada was issued on September 12, 1791. The governor-in-chief, Lord Dorchester, kept authority over both Upper and Lower Canada. Simcoe entered Upper Canada on June 24, 1792, and gave his first speech to the legislature at Newark (now Niagara-on-the-Lake) on September 17, 1792.
Founding York
In August 1793 Simcoe began laying out York, which he intended as a temporary capital. The site was the one earlier called Toronto, and sources place the renaming in late August 1793. Accounts differ on the exact day and on the reason. The Ontario Heritage Trust ties the name to the Duke of York’s victory over the French at Famars, while a study of Niagara place names questions that popular explanation and points to documents dated August 24 and 26, 1793. The older name is discussed in the article on the origins of Toronto’s original name. The town took the name Toronto again in 1834, according to the Ontario Heritage Trust.
Simcoe’s successor Peter Russell kept the move of the capital to York and met the first parliament there in June 1797. Russell’s years are covered in his own biography.
Roads and the Queen’s Rangers
Simcoe treated roads as a matter of defense and settlement. Work on Dundas Street began in May 1793. The road he named after Sir George Yonge, whom the Canadian Encyclopedia describes as secretary of war in the British Cabinet and a family friend, was cleared by the Queen’s Rangers working with the surveyor Augustus Jones, starting at Holland Landing and moving south toward York. The Dictionary of Canadian Biography adds that William Berczy had built the southern half and that the Rangers extended the road north to the Holland River in February 1796. Sources differ on the completion date: the Canadian Encyclopedia gives February 20, 1796, while the Ontario Heritage Trust plaque and a Toronto Public Library blog post give February 16, 1796. The later history of the street is told in the article on Yonge Street. The Rangers were disbanded in 1802, having served mainly as road builders.
The 1793 slavery act
In May 1793 Simcoe sought immediate abolition of slavery in the province. The assembly required gradual abolition instead, and the act received royal assent on July 9, 1793. It barred bringing more enslaved people into Upper Canada and provided that children born to enslaved mothers would be freed at age 25, according to the Ontario Heritage Trust. It freed nobody who was already enslaved, and slavery continued in the province after it passed. Enslaved people lived in York itself, including in the household of his successor. The article on Black history in Toronto gives the longer story.
Land policy and criticism
Simcoe granted large tracts of land, including the contested grant to William Berczy, and was criticized for weak administration of land titles. The district land boards set up in 1788 were abolished in 1794 after Simcoe secured it. His family held its Upper Canada lands until 1832 and then sold them over the next 21 years. Castle Frank, the Simcoe summer house on a slope above the Don Valley, was unfinished when the family left, and accounts say it burned in 1829.
Departure and death
Neuralgia and gout forced Simcoe to leave Upper Canada on a leave of absence in July 1796, and he resigned in early 1798. He was promoted to major-general on October 3, 1794, and to lieutenant-general on November 10, 1796. He left his post as governor of St Domingo (Haiti) in July 1797 and took command of the Western District at Exeter in December 1797. In July 1806 he was named commander-in-chief in India, fell ill, and died at Exeter that October.
