9.3.2.1. — Grade Marking

(1) Lumber for joists, rafters, trusses and beams and for the uses listed in Table 9.3.2.1. shall be identified by a grade stamp to indicate its grade as determined by the NLGA, “Standard Grading Rules for Canadian Lumber”.

Editor's note

O. Reg. 503/09 amends Sentence 9.3.2.1.(1) of Division B by striking out '(Interpretation Included)' at the end of the quoted standard title, which leaves the closing quotation mark of “Standard Grading Rules for Canadian Lumber”; this map applies that wording. The e-Laws consolidation editorially also drops the trailing closing quotation mark, leaving the opening quotation mark unclosed, with no amending regulation making that change. This map preserves the as-filed wording.
