=== Ojibway Phase: 9,160–8,480 YBP === [[File:7,900 Glacial Lake Agassiz & Glacial Lake Ojibway (7900) use fileTeller and Leverington, 2004.jpg|thumb|Map of Glacial Lake Agassiz and Lake Ojibway c. 7900 YBP. Designed from Teller and Leverington, 2004 (U.S. Geological Survey)]] The Ojibway Phase is named for the glacial lake along the ice front in northern [[Ontario]]. [[Lake Ojibway]] merged with Lake Agassiz at this time. Isostatic rebound of glaciated lands that were south of the ice sheet created a long linear lake from the [[Saskatchewan]]–[[Manitoba]] border to [[Quebec]]. This long lake drained through the eastern outlet at {{ill|Kinojevis River|fr|Rivière Kinojévis}}, into the [[Ottawa River]] valley.<ref name=Michalek/> Lake Agassiz-Ojibway drainage raised sea levels. The results can be seen in [[Nova Scotia]], [[New Brunswick]], and eastern [[Maine]]. Marine records from the North Atlantic have identified two separate episodes, linked to northern hemisphere cooling in 8,490 YBP and 8,340–8,180 YBP. These may be linked with the Ojibway Phase of Lake Agassiz and may indicate large amounts of drainage from the Ottawa River valley and the [[Tyrrell Sea]] (ancestral Hudson Bay).<ref name=Michalek/> The Laurentide Ice Sheet continued to recede. Continued warming shrank the ice front towards present day Hudson Bay. Here, the Lake Agassiz northward outlet drained into the Tyrrell Sea. This breach dropped the water level below the eastern Kinojevis outlet. The drainage was followed by the disintegration of the adjacent ice front at about 8,480 YBP. This brought on the end of Lake Agassiz. The ice sheet continued its northward retreat to [[Baffin Island]], leaving the North American mainland around 5,000 YBP.<ref name=Michalek/>
