As was reported in Torys' December 2008 EHS Bulletin, City of Toronto By-law 1293-2008, Environmental Reporting and Disclosure, came into effect on January 1, 2010. It requires certain businesses and facilities to track and report annually on their uses and releases of 25 specified substances. Different mass thresholds – ranging from 10 to 200 kg per year – apply for the reporting of the listed substances. Reporting will be introduced over the next three years in three phases. By June 30, 2011, facilities covered by phase one, including chemical manufacturing, power generation and wood industries, must submit a report to the City of Toronto about their uses and releases of the specified substances in 2010.
