"In 1991, archaeologists Patrick Julig of Laurentian University and Peter Storck of the Royal Ontario Museum in Toronto led new expeditions to Sheguiandah, and, armed with advances in dating techniques, re-evaluated Lee's claims. They determined that the site was roughly 10,500-years-old, instead envisioning Paleo-Indians as the site's first and only inhabitants after the conclusion of the Ice Age. At the time, Manitoulin Island was almost certainly connected to what is now mainland Ontario, and the inhabitants likely traded their stone tools far and wide."

And after Julig and Storck re-excavated Sheguiandah, Wilson and Burns reviewed all the pre-glaciation sites in Canada at that time.

Wilson and Burns referenced the publications by Lee and his son (1957-72 and 1986) and rejected all sites that predate the last glaciation. The only exception was Bluefish Caves which are not south of the ice sheets so are not relevant to the claims made for the Sheguiandah Site or all the others.
