John Macdonald (December 27, 1824 – February 4, 1890) was a Canadian merchant, churchman, philanthropist, and politician in the late 19th century in Toronto. He was a major patron of YMCA and the Toronto General Hospital. In 1860, he built a mansion called 'Oaklands', which is now De La Salle College (Toronto), a private co-educational school in the Deer Park area of mid-Toronto.
