Port Franks is a small
Southern Ontario community in the municipality of
Lambton Shores,
Lambton County in
southwestern Ontario,
Canada. It is located along
Kings Highway 21 near
Pinery Provincial Park, about north of
Thedford, Ontario. Archaeological evidence suggests that human habitation and use of this site date back thousands of years, and that locally obtained flint was manufactured at the so-called 'flint chipping beds' in the vicinity long before the period of European contact with First Nations peoples in the
Great Lakes Basin. The "Port Franks" reserve (named for company official Charles Franks and not, as is commonly reported, a Lake Huron sloop captain) was initially laid out by the
Canada Company north of the present day village of Grand Bend. However, by 1851 its location was moved south to near the mouth of the
Ausable River.
