42.Subsection (1) of section 26 enables the Commissioner to revoke a compliance notice if the Commissioner so wishes. Subsection (2)(a) provides that the revocation of a compliance notice can only take place before the steps specified in the compliance notice have been taken. This prevents a compliance notice from being revoked after completed action has already been taken specifically because the notice required it. Subsection (2)(b) provides that a compliance notice can only be revoked by the Commissioner by giving notice in writing to that effect to the person to whom the compliance notice was issued.
