When a deed near Bellville says lot and block, look up the Ontario plat map it refers to. Covered here for Ontario: where plats are filed, plat versus tax map, and what to look for on the sheet.
Who keeps the Ontario plat map
Around Mansfield, recorded plats sit with the County Recorder, usually in a plat book or cabinet.
Getting to the right map
Go first to the Richland County Beacon site; it maps every assessed parcel around Bellville and Shelby. Around Mansfield, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Lucas, write down the parcel ID before closing the panel; every office in the county asks for it first.
Taking the map into the field
