TEA’s CRTK campaign was launched in 2004. Over the course of the campaign, the popular Toxics in Toronto map captured the attention of Torontonians. It raised awareness of toxic chemical releases across Toronto and encouraging City Council to pass a Community Right to Know Bylaw to give residents access to information about toxic chemicals used, stored, and released in their neighbourhoods.  

The campaign was a success, and the bylaw, officially called the Environmental Reporting & Disclosure By-law was passed in December 2008 and came into effect in January 2010. June 2012 marked the first year chemical use and release data was publicly disclosed online through the ChemTRAC Program
