I see that the Provincial Policy Statement (PPS) has been amended again by the current Ontario government. Among other changes, the revised PPS specifies that the Ontario Municipal Board is empowered to refuse appeals by developers to rezone employment lands to residential lands.

That should make it easier for Orangeville and other Dufferin County municipalities to reject zoning appeals from residential developers, and to retain employment lands for their intended purpose.
