Editor's note
As filed in O. Reg. 350/06, Sentence (4) of this article reads 'reduced in accordance with Sentences (2) or (3),' (plural 'Sentences'). The consolidated e-Laws text renders this in the singular ('Sentence'); this wording difference was not enacted by any amending regulation, and the as-filed text is retained here.
