No.  COR certification is awarded to an individual company based on their implementation of an appropriate health and safety program.  However, we recognize that it is possible for more than one company to fall under the umbrella of a single health and safety program, particularly when there is common ownership, management and/or workers.  If this is the case, you can apply for Multiple Company status.  The Multiple Company Application form is available online.  In order for the COR certification to extend to the new company, the NLCSA will have to conduct an External Audit on the operations of that company.
