Not all information and statements in the report necessarily ref lect the views of the Governments of Canada, Mexico and/or the United States, or the CEC Secretariat, IJC, PAHO and/or WHO, in part because the report is a compilation of information provided separately by the three different countries. [...] It is the culmination of many months of work by dedicated people from across the continent and globally, representing the governments of Canada, Mexico and the United States and the partner institutions, namely CEC, IJC, PAHO and WHO. [...] From the initial planning stage and feasibility study, through the creation of the country reports, and fi nally to the completion of this fi rst-ever North American report, this has been a truly collaborative endeavor involving numerous people from the Governments of Canada, Mexico and the United States, the Commission for Environmental Cooperation (CEC), the International Joint Commission (IJC), [...] It would be impossible to overstate the important contribution of the panel of experts who generously gave of their time and expertise to the development and improvement of the report. [...] Erica Phipps, former program manager for the CEC’s work on children’s health and the environment and now a consultant to the CEC, has coordinated the work of the Steering Group since its inception and was instrumental in getting the project off the ground.
