Editor's note

As filed in O. Reg. 350/06, Clause (2)(a) of this article reads 'reserved,' (lower case, ending in a comma that separates it from the following clause). The consolidated e-Laws text renders this clause as 'Reserved' (capitalized, with the comma omitted); this presentation difference was not enacted by any amending regulation, and the as-filed text is retained here.
