Laurentia

A New Latin formation named after the Saint Lawrence River: Laurentius (“Lawrence”) +‎ -ia (New Latin suffix for creating place names). Or, back-formed from Laurentian (from French laurentien), already in use to describe the Laurentian Mountains and their associated geologic complex (and by extension Canada as a whole). (Can this⁽⁺⁾ etymology be sourced?)
