The Laurentian River System is an ancient river in southern Ontario, Canada.〔 〕〔 〕〔 〕〔 〕 The river predates the recent ice ages. The river valley was filled with glacial debris. Water still flows down this old valley -- underground. The source of the aquifer is the Georgian Bay, approximately away. In 2003 it was discovered that the southern section of the Laurentian aquifer reaches under High Park in Toronto, Canada.〔 This is believed to be where the Laurentian River System drains into Lake Ontario. ==References== 〔 ==See also== *List of rivers of Ontario
