Editor's note

In Sentence (2) of this article, the as-filed O. Reg. 350/06 writes the defined term as 'Post disaster buildings' (two words), whereas it appears hyphenated ('Post-disaster') everywhere else in the regulation; this map reproduces the source as filed. The e-Laws consolidation normalizes this single occurrence to the hyphenated form. This wording difference was not enacted by an amending regulation.
