Editor's note

The note to Table 3.1.13.7. is reproduced here as filed in O. Reg. 350/06. The consolidated e-Laws text applies editorial formatting changes that were not enacted by any regulation; this map preserves the note as filed. The differences are: the heading "Note to Table 3.1.13.7:" appears in bold as filed and is rendered in regular weight on e-Laws, which also adds a trailing period to the table number ("3.1.13.7."); and a space follows each note number ((1) and (2)) as filed, which e-Laws omits.
