Editor's note
As filed in O. Reg. 350/06, Sentence (8) closes 'shall conform to Clauses 12.2.1.1.(2)(a) or (b)' with the plural 'Clauses'; the e-Laws consolidation renders the singular 'Clause 12.2.1.1.(2)(a) or (b)', with no amending regulation making the change. This map preserves the wording as filed.
