Laurentian River System (Ontario)
- Laurentian River System (Ontario)
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 thought to be near Georgian Bay, approximately 200 km away.
In 2003 Toronto city workers discovered deep, powerful artesian springs in High Park. This is believed to be where the Laurentian River System drains into Lake Ontario.
