A/HRC/45/12/Add.1 (p) Include workers as a vulnerable group under its Chemicals Management Plan and expeditiously re-evaluate previously assessed substances from the perspective of individual workers’ exposure to toxics; (q) Ensure that mine-related regulatory structures incorporate robust planning for mine closures before projects have been developed or assessed, and enforce strict financial penalties to ensure industry accountability for the long-term care of mines; (r) Take stringent measures to halt economic and political support to business enterprises operating abroad where human rights abuses are reported; (s) Respect concerns expressed regarding the risk of harm, including where host countries have established no-go zones for resource extraction, to guarantee accountability and ensure access to justice for people affected by the activities of Canadian enterprises abroad; (t) Implement legal requirements for robust mandatory human rights due diligence and provide redress where activities of business enterprises both at home and abroad are associated with impacts of toxic exposure, with a cause of action for victims both in the host country and in Canada; (u) Expand the mandate of Office of the Canadian Ombudsperson for Responsible Enterprise to include other economic sectors, providing additional investigative powers, including the ability to compel the provision of documents and testimony, and providing the resources required for it to carry out its mandate; (v) Revise the avenues available to access justice, to give full effect to the justiciability of economic, social and cultural rights through the court system in Canada, engaging civil society and indigenous peoples in that revision; (w) Conduct continuous national and regional cumulative environmental and socioeconomic assessments, including environmental health inequality assessments, and facilitate environmental justice mapping; (x) Establish a sound environmental justice framework based on the principles of procedural justice, geographic justice and social justice; (y) Involve indigenous peoples and other population subgroups in selfassessments to complement assessments by members of other population subgroups. 112. The Special Rapporteur recommends that business enterprises in Canada: (a) Invest in technologies to phase out chemicals of concern and increase the traceability and transparency of chemicals in products, especially consumer products; (b) Take proactive measures to prevent environmental harm and respect concerns of risk of harm, including where host countries have put in place no-go zones for resource extraction; (c) Implement robust and transparent human rights due diligence and provide redress when activities, whether carried out in Canada or abroad, cause, contribute to or are linked with impacts of toxic exposure. These processes should oblige business enterprises to undertake human rights risk assessments in respect of their activities throughout the supply chain. 23
