106. Modification, variation or revocation of a mandatory standard

The Commission may determine the modification, variation or revocation of a mandatory standard, in accordance with section 55, if it is satisfied that the mandatory standard is no longer consistent with all the matters listed in paragraphs 105(1)(a), (b) and (c).

Any modification or variation of a mandatory standard under subsection (1) shall be deemed to be a new standard for the purposes of this Chapter and shall be subject to the provisions of this Chapter.

If a new mandatory standard deals with the same standard as an existing mandatory standard, then the existing standard is taken to be invalid to the extent of any conflict with the new mandatory standard.
