The petition raises concerns about the growing environmental and human health risks posed by microplastics in Canada. According to the petition, these particles are widespread in water, soil, air, wildlife, and humans. The petition argues that although some health effects remain uncertain, the level of exposure and potential risk warrant engaging the precautionary principle under subparagraph 2(1)(a)(ii) of the Canadian Environmental Protection Act. The petition highlights Canada’s existing commitments to reducing plastic pollution and emphasizes that addressing microplastics would support federal responsibilities under legislation such as the Fisheries Act and the Species at Risk Act.
The petition claims that a major source of microplastic pollution is synthetic textile microfibres that shed during laundry cycles and contaminate aquatic ecosystems through wastewater and the land application of biosolids. The petition highlights that microfibre filtration technologies for laundry appliances are an effective upstream solution. Citing a recent unanimous decision from the Federal Court of Appeal affirming the government’s authority to list plastic manufactured items under Schedule 1 of the Canadian Environmental Protection Act, the petition calls on the government to address microplastic pollution and its impacts.
The petition asks whether the federal government will:
- integrate microplastics into the Canada-wide strategy on zero plastic waste
- enhance wastewater treatment facilities to improve microplastic removal
- fund the research and development of biodegradable textiles and dyes
- introduce regulations that require all new washing machines and dryers to have built-in microfibre filters
- undertake long-term research on the health impacts of microplastics on vulnerable populations
- launch a public education campaign on microplastics
- include microplastic pollution literacy in school curriculums
