The federal government is moving to add Per- and Polyfluoroalkyl Substances (PFAS) to the official list of toxic substances. Due to their ability to repel oil and water, PFAS are used in a range of products and commercial applications, as well as in industrial sectors. These chemicals are found in packaging, cosmetics and textiles, and industrial products such as water-repellent coatings and firefighting foam. In humans, PFAS exposure can affect multiple organs and systems, including the liver, kidneys, thyroid, immune system, nervous system, metabolism and body weight, and reproduction and development. In the environment, the effects of PFAS on wildlife include toxicity to the immune and nervous systems, and general effects on growth, reproduction and development. It has also been shown that certain PFAS may build up in living organisms and magnify up the food chain.

This announcement will not immediately ban any new PFAS but will start a process to restrict them in the future. The government has started a 60-day consultation period, which is required before adding PFAS to the toxic substances list.The government will first focus on restricting PFAS in firefighting foams. Then, it will look at PFAS in cosmetics, non-prescription drugs, food packaging, textiles and certain building materials, cleaning products, and waxes and polishes. Addressing the widespread use of these chemicals has become a global concern due to the significant exposure humans have already experienced.

Canada collaborates with other countries to address PFAS and will continue to rely on the best available science to protect the health of people and the environment. Learn more on the Government of Canada’s website.
