Charles Unwin (b.1829 d.1918-01-05) was a prominent surveyor for the Province of Ontario and the City of Toronto. Unwin was born in the United Kingdom, and emigrated to Toronto in 1843, and lived with his uncle -- also named Charles Unwin. Unwin attended the prestigious Upper Canada College, a private high school attended by many of the leading elements of Ontario's administration. After graduation he apprenticed with John Stoughton Dennis, completing his apprenticeship in 1852. He spent the next nine years surveying Muskoka County.
Unwin never married. He worked as a surveyor for Toronto from 1874 to his death, at 88 in 1918.
