Is an Oshawa address in the Greenbelt or the Oak Ridges Moraine?

The Province's Greenbelt map series names the City of Oshawa on two Protected Countryside sheets shared with Clarington, Scugog, Whitby, Pickering and Ajax, and on Urban River Valley sheets for Oshawa Creek and Harmony Creek; additions in 2022 extended the Oshawa Creek valley and added Darlington Provincial Park, in Oshawa and Clarington. The Province notes that in Urban River Valley areas the Greenbelt Plan's policies apply only to publicly owned land. In 2017 land northwest of Winchester Road East and Ritson Road North was removed from the Protected Countryside.

The Oak Ridges Moraine Conservation Plan's sectional Map 6 covers Scugog, Whitby and Oshawa, and the moraine's boundary sheets 8 and 9 list Oshawa; the City's zoning by-law has moraine zones of its own, such as OS-ORM and AG-ORM. The Greenbelt Plan's Schedule 1 counts the Oak Ridges Moraine Area as part of the Greenbelt Area. A result from the provincial layers says whether an address falls inside a mapped area and which designation; it is a planning boundary, not a statement about what a particular lot may be used for.

The Greenbelt, Moraine and Escarpment check runs for any Ontario address, in the free check and in the full report, from the Province's layers, and names the designation where one applies. It reads the mapped boundaries; it doesn't say which parcels in a creek valley are publicly owned.
