In 2008, Canada became the first country to complete a comprehensive human and environmental risk assessment of BPA, in consultation with industry and other stakeholders, and to announce it would take regulatory action to reduce the chemical's presence.
As preliminary data from that assessment was released, Canadian health officials said that the endocrine-disrupting chemical posed the greatest risk to newborns and infants up to 18 months of age. The main source for infant exposure to BPA was reported to be through baby bottles containing the chemical as an interior lining and the migration of BPA from cans into infant formula.
An April 2008 news release from Health Canada officials announced the government's intention to ban the sale, import, and advertising of polycarbonate baby bottles containing BPA.
The final assessment report concluded that bisphenol-A should be "considered as a substance that may be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health."
But the first step toward banning the chemical was for Health Canada to deem it a "dangerous substance" and list it on the country's the toxic substances list under the Canadian Environmental Protection Act. However, no action was taken to designate BPA as a listed toxic substance until now, due to a formal notice of objection brought by the American Chemical Council (ACC) in 2009.
ACC, which maintains that BPA does not pose a significant risk to human health, demanded that the Canadian government establish a board of review to reconsider the proposed toxic listing of BPA. In a letter to Environment Canada, executive director of ACC Steven Hentges said permitting BPA to be designated as a toxic substance would not be "based on the best available data and scientific knowledge."
Despite the ACC's efforts to challenge the designation, Canadian Minister of the Environment, Jim Prentice, rejected the industry group's demand. In a July 2010 response, Prentice stated "I am of the view that your notice does not bring forth any new scientific data or information."
After the 2-year delay, Canada is now poised to include BPA on its toxic substances list by November.
