Creighton (near Sudbury) has been one of the ghost towns featured in the CBC series. The site has 2 caches
(one near the memorial plaque). CCI3NH1, GCP339
The French River village that had a monsterous turn-of-the-century limber trade has 2 nearby.

The original Wabi settlement (New Liskeard) has NOGST030 nearby..
The idea of ghost town caches accompanied by some sort of local history is pretty appealing.
Another thing I find fitting would be to create caches with documentation, if necessary, near the original site of relocated graveyards. Ontario is rife with situations where small community graveyards have lost an expropriation battle to the mighty highway.
