I will try to draw a rough map, although I doubt there will be any question in the fact that I will most likely be wrong.

They were located in south eastern Quebec and Ontario. Notice that a huge provincial park in southern Ontario bears their name, Algonquin Park, as well as some colleges and tourist agencies in the region.

The blue/green is where they would most likely inhabited. They would also lived a bit more south on lake Huron, I forgot to add it though!





Forget the green in the bottom right. and maybe they woudn't have lived as far east as that. But that is the general area.
