From the time that a company receives its COR^® certification it is another year before the Internal Audit is due and three years before another External Audit is due. That’s a long time between audits. Is there an opportunity for another External Audit before then?

Yes, six months after the initial External Audit NLCSA may conduct an interim audit at no charge, if in the opinion of the auditor, the company would likely need assistance.  Also, a COR^® company can request extra External Audits at any time outside of their normal audit cycle, however, it would be at cost, plus all travel expenses.  (The standard flat fee for an External Audit, that is part of the normal audit cycle, is $525 plus HST including all travel expenses, as it is subsidized by the construction industry levy.)
