Joseph Rowntree (Canadian)
Joseph Rowntree was pioneer in north Etobicoke village of Thistletown and established two mills on the banks of the Humber River. In 1843 he built a sawmill on the east bank of the river. Five years later, he built a grist mill on the west bank. His mills were known as the "Greenholme Mills" and operated until the end of the nineteenth century.
A park in the area was named Rowntree Mills Park in 1969 in honour of Rowntree.
Rowntree is not related to father and son Joseph Rowntree of the Rowntree's chocolate fame.
