Champlain Sea  Mer de Champlain
A cold, brackish and short-lived (12 000 – 9500 years ago) marine invasion of the St-Lawrence Lowlands and part of the Ottawa River Valley marking the end of the Wisconsinan Glaciation. The Atlantic Ocean invaded westward due to both the increase in sea level from the meltwater released by the waning glacier, and because of the isostatic depression of the recently glaciated land.
