Editor's note

As filed in O. Reg. 350/06, Sentence (3) of this article reads 'For the purpose of Clause (2)(c) and Clause 2(d),' - the second reference appearing in the malformed form 'Clause 2(d)' as enacted. The consolidated e-Laws text rewrites it as 'Clause (2)(c) and (d)'. The headnotes of Tables 3.3.1.5.A. and 3.3.1.5.B. are also filed in bold with a space following the footnote marker '(1)'; the e-Laws text removes the bold weight and that space. None of these differences was enacted by any amending regulation, and the as-filed text is retained here.
