Overview

Orphaned and abandoned mines are two types of legacy mines. Orphaned mines are defined as those for which the owner cannot be found and abandoned mines are defined as those for which the owner is financially unable or unwilling to carry out the clean-up. These mines exist within all mining jurisdictions in Canada and pose environmental, health, safety, and economic issues for communities, the mining industry, and governments.

Canada is a global leader in research and development to address environmental issues caused by legacy mine sites.

Orphaned and abandoned mine (OAM) sites are poorly documented in terms of their numbers and the physical, health, and environmental impacts and liabilities. Therefore, research, collaboration, and information sharing are crucial for informed decision-making, cost-effective planning, and sustainable reclamation. National, multi-stakeholder collaboration is essential to guarantee transparency in decision-making and access to information for governments, industry, Indigenous communities, and other stakeholders.

Annual Orphaned and Abandoned Mines Workshop

Inaugurated in 2023, the Annual Orphaned and Abandoned Mines (OAM) Workshop is a multi-day, working-level workshop aimed at facilitating information sharing, diverse and inclusive engagement, and broad collaboration on challenges related to orphaned and abandoned mines. This workshop replaced the National Orphaned/Abandoned Mines Initiative after its dissolution in 2022. It is hosted by the Canadian Minerals and Metals Plan (CMMP) Secretariat and the Task Team on Environment under the Mines Intergovernmental Working Group (Mines IGWG).

2nd Annual Workshop

Ended October 2024

The 2nd Annual OAM Workshop took place virtually on October 23-25, 2024.

The theme of this virtual workshop was “Foundations for Success: Building Capacity and Developing Exemplary Practices.” It included sessions focused on exemplary practices for remediation planning and implementation; potential economic opportunities and partnerships, including creating value from mine tailings, and their associated considerations, risks, and challenges; considerations and approaches in clean-up, restoration, and remediation science and practices; addressing capacity constraints, developing supportive relationships, and providing opportunities for Indigenous Peoples and communities; and building strong, collaborative, and effective partnerships.

The workshop saw a high level of engagement from a wide variety of individuals and organizations, who highlighted the importance of continuing to advance OAM remediation, as well as the importance of events such as the Annual OAM Workshop for fostering connections and sharing information.
