On the BGG page of Tryopoly it sayes
The properties in this game were meant to be local and recognizable to the players, so there is no "official" version of this game. Each version features a different city (such as Cleveland, Kansas City, and Washington D.C.) and the businesses and organizations found there.
There are severals editions (different citys) listed here on BGG, but your´s is missing and I guess there are more.
As Canton is not that big, the Canton edition might be quite rare, but thats just an assumption.
