Editor's note

The notes to Table 3.1.13.2. are reproduced here as filed in O. Reg. 350/06. The consolidated e-Laws text applies editorial formatting changes to these notes that were not enacted by any regulation; this map preserves the notes as filed. The differences are: the heading "Notes to Table 3.1.13.2.:" appears in bold as filed and is rendered in regular weight on e-Laws; a space follows each note number ((1) and (2)) as filed, which e-Laws omits; and the reference in note (1) reads "Articles 3.1.13.8. and 3.1.13.10" as filed, to which e-Laws adds a trailing period ("3.1.13.10.").
