The science hasn't been done yet. The science is still very much in flux.
The federal government would need to do a risk assessment to determine what the impacts are. A draft science assessment was conducted by Health Canada and Environment Canada. It was primarily a review of the state of science, and it identified the fact that plastics are problematic in the environment, but there are no material impacts at this point because the science is just not available yet in terms of human health. More work needs to be done there.
The confusion is if you have campaign organizations that say that plastics are toxic and are sharing that information with the public. Plastics are ubiquitous. Your headset is made of plastics. There are plastics in your clothing. It becomes a problem in terms of trying to ensure that consumers are comfortable with products.
