Where multiple dates were run on the same short-lived sample, we used the weighted average (R_Combine in Ox Cal) but added an additional 8 ). Where there is an internal sequence within the site Phase from archeological investigation, we also considered models incorporating these known archeological Sequences within the relevant site Phases (figs.

Otherwise, an assumed refined chronology for the late prehistoric period has been based on the initial appearance and then the abundance of types of European trade goods (for example, presence/absence of types of metals and presence/absence of types of glass beads).

de Champlain in 1615–1616 CE, yields a compatible radiocarbon-based age.

However, a well-known late prehistoric site sequence in southern Ontario, Draper-Spang-Mantle, usually dated ~1450–1550, yields much later radiocarbon-based dates of ~1530–1615.
