Regions of Ontario

[King of Kensington]

Obviously there's the big two, Northern and Southern Ontario which are different worlds though whether Parry Sound and perhaps Muskoka belong in Northern Ontario is a point of contention.  But then Northern Ontario can be split into NE and NW Ontario (the former being much more Franco Ontarian) and southern Ontario itself has southwestern, eastern, central etc.?  How would people divide up Ontario's regions?
