October 7, 2021
to December 6, 2021

Proposal summary

We are proposing to update aspects of the regulatory framework for mineral development in Ontario for activities that have been identified as having a lower potential for environmental impact which in turn may correlate to a lower potential for impact to Aboriginal and/or treaty rights.

Proposal details

We are proposing opportunities to update aspects of the regulatory framework for mineral development in Ontario. In reviewing these opportunities, Ontario is considering how it can create a more flexible regulatory environment for exploration and development for all proponents, particularly for early-stage and startup proponents and/or proponents targeting newer commodity markets, in a manner consistent with the recognition and affirmation of existing Aboriginal and treaty rights in section 35 of the Constitution Act, 1982, including the duty to consult, and to minimize the impact of these activities on public health and safety and the environment. The proposal outlines the Ministry’s preliminary thinking on opportunities to improve Ontario’s graduated approach to advanced exploration and mine production rehabilitation and closure requirements.


The Ministry appreciates the significance of mining regulation, and will keep the following principles in mind when making decisions:

  • Any impacts on public health and safety, and the environment must be minimized.
  • New global investment, and expansion of the mining industry, which will create new jobs and support partnership opportunities for Indigenous communities must be promoted.
  • There must continue to be transparent, meaningful engagement of the public, stakeholders and rights holders.
  • The Crown must continue to meet its constitutional obligations to Aboriginal peoples.

To this end, the Ministry is seeking input on:

  • rehabilitation and regulatory requirements for closure plans, and
  • financial assurance.

We pose a series of questions in the proposal. Your feedback on these questions is critical as Ontario considers how it will proceed with the development of the framework.


Commenting is now closed.
