Previous Environmental and Indigenous Experience

Prior to joining Willms & Shier Environmental Lawyers, Amanda worked for the Government of Canada.

At the Impact Assessment Agency of Canada, Amanda led Crown consultations with Indigenous communities on major resource development projects in Ontario. Prior to that, at Crown-Indigenous Relations and Northern Affairs Canada, Amanda provided policy support for Canada’s negotiation of modern treaties and self-government agreements with Indigenous communities across Canada.

Amanda graduated from the joint JD/MES program at Osgoode Hall Law School/York University. In law school, Amanda took part in the Environmental Justice and Sustainability Clinic and interned with a BC-based public interest environmental law organization. In this role, Amanda provided legal support for the organization’s efforts to enhance new federal legislation relating to impact assessment. As a research assistant to an environmental law professor, Amanda conducted legal research on litigation across Canada involving the Crown, resource development companies, and Indigenous communities to understand the ways in which the assertion of Indigenous jurisdiction has been understood by the courts. 

During law school, Amanda spent a summer with the Ontario Ministry of Environment, Conservation and Parks, and provided legal support on environmental prosecutions and on hearings before administrative tribunals. Amanda also spent a summer with a BC-based public interest environmental litigation organization, and assisted with ongoing litigation for First Nations clients relating to a major hydroelectric development in BC. 
Amanda has provided research and editorial assistance for multiple environmental legal publications, including book chapters, loose-leaf publications, and academic journal articles.
