Editor's note

In Sentence 4.4.4.1.(2), the title of CSA Standard Z91 is filed in O. Reg. 350/06 with a space after the opening quotation mark (“ Safety Code for Window Cleaning Operations”); this map reproduces the source as filed. The e-Laws consolidation removes that space. This punctuation difference was not enacted by an amending regulation.
