Continental glaciation is an interesting phenomena.
The trouble I have with this "It all got worn away" idea is why didnt the same thing happen to Aber and Diamet to the north and Mountain Province to the SE>
I can vaguely understand how a tree might get caught up and end up in a kimberlite a hundred or so feet down, but how would it get down kimometers? as your errosion theory predicts.
Assuming the earths crust is aproximately the same depth at all three sites then the pipe (feeder system) extents all the way down to the mantel, this would leave the aproximate same mining depth for all three sites (depending on cost and grade of course).
As far as I know the precambrian shield is the basement complex in the north and always has been. So if you set up a drill and drill straight down you continue in the shield untill you hit the mantel.
Unless you recon the center of the earth is hollow and has trees growing there Im a little confused as to your thinking here.
I'll be the fist to admit that geology is full of surprises but if your theory were true an awfull lot of geological tombs would have to be rewritten.
