The Peterborough graticule is at latitude 44, longitude -78. It includes Peterborough, Lindsay, practically the entire Kawartha Lakes region, and cottage country from Rice Lake almost up to Haliburton. It is likely that Ontarians from Bomanville eastward would use this graticule rather than the Lockport one.
