The "Jean-Baptiste Lainé" or Mantle Site in the town of Whitchurch–Stouffville, north-east of Toronto, Ontario, Canada, is the largest and most complex ancestral Wendat-Huron village to be excavated to date in the Lower Great Lakes region.

[4] In 2012, archaeologists revealed that they had discovered a forged wrought iron axehead of European origin, which had been carefully buried in a longhouse at the centre of the village site.

It is believed that the axe originated from a Basque whaling station in the Strait of Belle Isle (Newfoundland and Labrador), and was traded into the interior of the continent a century before Europeans began to explore the Great Lakes region.

The layout displays a uniquely high degree of organization (when compared, e.g., to the Draper Site), and includes an open plaza and a developed waste management system.

... it would appear that refuse was directed out of the interior of the village into a borrow trench situated on the outside of the palisade—thereby representing one of the first organic and inorganic waste stream management systems known in the northeast.

These are similar to ones found at on contemporaneous Oneida villages in New York State, indicating the cosmopolitan nature of the community that settled the Mantle Site.

[21] The consequent development of the west side of the creek in the Fieldgate River Ridge subdivision around James Ratcliff Avenue was delayed significantly.

[30] Radiocarbon dating of charcoal and short-lived botanical material late in the second decade of the twenty-first century and Bayesian analysis[3] has resulted in a re-dating of the Mantle Site to a fairly precise time period, to wit 1587-1623 (with 95.4% probability).

[3] This analysis has also resulted in the redating of the related Draper and Spang sites, with conclusions about the speed of change among the region's indigenous peoples in this period.

[31] The Huron, and other local First Nation peoples, have urged towns and developers in York Region to preserve indigenous sites so that they may "worship at the places where [their] ancestors are buried.

"[32] The discovery of a sixteenth-century European axe at Mantle is also of political importance for the Wendat First Nation, for its current negotiations with federal and provincial governments.
