The Cantonica system, a star system situated within the Corporate Sector of the galaxy's Outer Rim Territories, encompassed the planet known as Cantonica.
As per the map featured in Star Wars: Galaxy's Edge: Traveler's Guide to Batuu, Cantonica's location is within grid square R-5, a designation found in Star Wars: The Force Awakens Beginner Game; nevertheless, this grid square diverges significantly from the Corporate Sector's mapped position. Jason Fry has advised viewers to "disregard that placement". Star Wars Galaxy Map positions Cantonica in the Corporate Sector, specifically at grid square S-4.
