The Ratcliff or Baker Hill Site is a 16th-century Huron-Wendat ancestral village located on one of the headwater tributaries of the Rouge River on the south side of the Oak Ridges Moraine in present-day Whitchurch–Stouffville, approximately 25 kilometers north of Toronto.

The artifacts found on the site in the mid-19th century included stone-axes, flint arrows and spear heads, broken crockery, many earthen and stone pipes, bears' teeth with holes bored through them, polished teeth of beaver, deer and moose for decorative use; bone needles, and fish-spears made of deer shoulder-blades, as well as millstones used by the women for crushing corn.

"[4] The ceramics found on the site indicate that the local community must have had some contact with other Iroquoian groups living in present-day upstate New York and in the St. Lawrence Valley.

[2] The presence of some contact-period (European) artifacts, such as black glass and copper beads, suggest that the site was inhabited between the late 16th and early 17th centuries.

About 400 meters north of the Ratcliff Site on lot 10 in concession 8, a mass grave with "many hundreds" of Huron skeletons was discovered and removed in the late 1840s.
