The results of the screening assessments conducted by the Ministers of the Environment and of Health pursuant to Section 74 of the Canadian Environmental Protection Act, 1999, for Bisphenol A was published in the Canada Gazette Part I on October 18, 2008.

In 2006, Bisphenol A was used in Canada in the range of 100,000 to 1000,000 kilograms and approximately half a million kilograms was imported into Canada, either alone, in a product, in a mixture or in a manufactured item, The screening assessment concluded that Bisphenol A has been found not to degrade slowly under low oxygen or no oxygen conditions. It has been detected in surface waters, sediment, groundwater and soil. While Bisphenol A has low bioaccumulation potential, the studies have confirmed that it is bio-available and can accumulate in tissues, to some degree. The screening assessment concluded that it is acutely toxic to aquatic organisms and has been shown to adversely effect growth and development in both aquatic a terrestrial species.

Human exposure to Bisphenol A is primarily through dietary intake. A critical effect for characterization of risk to human is reproductive and developmental toxicity. Limited human studies have indicated potential sensitivity of pregnant woman. The screening assessment concluded that as a result of the potential for long-term adverse to organisms and humans within the range of concentrations currently being experienced, the application of the precautionary principle suggest that it may constitute a danger in Canada to organisms as well as human life or health.

In response to the screening assessment, the Government of Canada announced that it would immediately proceed with drafting regulations to prohibit the importation, sale and advertising of polycarbonate baby bottles that contain Bisphenol A and would take action to limit the amount of Bisphenol A that is being released into the environment. Proposed regulations are expected to come into effect in 2009.
