The purpose of the Act is to encourage: - prospecting - online mining claim registration - exploration for the development of mineral resources

## Mining Act forms You may be required to submit a form to notify the ministry or get certain permissions required by the [Mining Act](https://www.ontario.ca/laws/statute/90m14). [Access all Mining Act forms](/page/mining-act-forms). ## Policies We developed a set of policies to help you understand the requirements under the [Mining Act](/laws/statute/90m14) and its regulations. To view a listing of the Mining Act policies, visit the [policies website](http://www.geologyontario.mndm.gov.on.ca/mines/lands/policies/default_e.html). ## Duty to consult with Aboriginal communities We made changes to the Mining Act in 2009, including new regulations to promote mineral exploration and development in a manner that recognizes Aboriginal and treaty rights. [The Consultation framework](/page/consultation-framework-implementing-duty-consult-aboriginal-communities-mineral-exploration) gives information and direction to proponents and Aboriginal communities on how the ministry implements the consultation framework set out in the Mining Act and regulations.

The program ensures that prospectors and exploration proponents are informed before engaging in prospecting and exploration activity. The MAAP covers topics such as: - the purpose of the Mining Act and its regulations, including the operational policies that outline how early exploration activities must be carried out in Ontario - Aboriginal and treaty rights - the rights of private landowners, and other users of the land when planning for early exploration activities - the requirements for carrying out early exploration activities - resources to help you with online mining claim registration and early exploration activities If you are completing MAAP to conduct business with the ministry and/or to satisfy a mandatory requirement under the Mining Act, you should complete MAAP through MLAS. Register for MAAP in your [MLAS account](https://www.one-key.gov.on.ca/iaalogin/IAALogin.jsp). ## Who must take the MAAP You must complete the MAAP if you: - are applying for or renewing an existing prospector's licence - hold a lifetime prospector's licence - are listed as a "qualified supervisor" on an exploration plan or permit - are a private landowner or a member or representative of an Indigenous community that may engage or work with prospectors and the mineral exploration industry You can also complete the MAAP if you are interested in the mining sequence or the Mining Act topics covered by the MAAP.

## Class Environmental Assessments A [Class Environmental Assessment](https://www.ontario.ca/page/class-environmental-assessments-approved-class-ea-information) (Class EA) describes a planning and decision-making process for groups (or classes) of activities where a proponent must conduct an environmental assessment. The classes of activities eligible for review under a Class EA must be routine in nature, with predictable and manageable environmental effects. A [Class EA for Activities of the Ministry of Northern Development and Mines](https://www.geologyontario.mines.gov.on.ca/mmd/mines/lands/class-ea/class_ea_approved_minor_amendments.pdf) (PDF) was approved under the Environmental Assessment Act on December 12, 2012. It was amended on July 3, 2014 and February 28, 2018. The Class EA applies to activities where the ministry has a discretionary decision-making ability. The classes of activities subject to the Class EA under the Mining Act includes: - discretionary tenure decisions related to surface rights, mining rights and chattels - discretionary mine hazard rehabilitation activities carried out by the ministry This publication is available in English only.
