During discussions connected with the U.S.-Canada Regulatory Cooperation Council, staff from the U.S. Consumer Product Safety Commission (CPSC) and Health Canada (HC) reaffirmed their commitment to collaboration in the development of the strongest possible toy safety requirements. Staff from both agencies participate in the ASTM International Toy Safety Subcommittee (ASTM F15.22), a standards development body of particular significance in North America. Most federal toy safety regulations enforced by the CPSC are, by law, derived from the ASTM consensus reference standard. In Canada, mandatory safety requirements for toys in the Canada Consumer Product Safety Act (CCPSA) and its associated regulations are established using various standards, including those set by ASTM. The aim of CPSC-HC collaboration in the F15.22 subcommittee is to maximize the potential for aligned positions at the highest possible level of safety between the two regulators as the ASTM standard is revised, thus increasing the likelihood of not only aligned approaches in the two jurisdictions, but also increased safety benefits for consumers.
