The Ontario Toxics Reduction Act, 2009 and Ontario Regulation 455/09 requires Ontario companies to annually track and quantify the amount of toxic substances used, created and contained in product, report actual amounts annually, and develop voluntary reduction plans on a facility-wide basis. Our quantification methods include monitoring, source testing, approved and generally-accepted emission factors, and engineering estimates.
