Mining Matters

About Mining Cases at the OLT

Mining cases at the Ontario Land Tribunal (OLT) relate to matters under legislation administered by the Ministry of Energy, Northern Development and Mines (MENDM) and the Ministry of Natural Resources and Forestry (MNRF). These matters can include the resolution of mining and lands disputes and appeals of decisions made by conservation authorities, which involve property owners who want to develop lands in floodplains and wetlands.

History of OLT mining cases

The OLT was formed with the proclamation of the Ontario Land Tribunal Act , 2021 on June 1, 2021. Before the formation of the OLT, mining cases were dealt with by the Mining and Lands Tribunal (MLT), whose role and jurisdiction has been assumed by the OLT.

With origins dating back to 1906, the purpose of establishing a Mining Commissioner was to resolve disputes under provincial mining legislation. In carrying out its functions under the Mining Act, the Mining and Lands Commissioner had exclusive jurisdiction over any matter arising under the Mining Act, and proceedings involving private civil and property rights, relating to or arising out of matters governed by the Mining Act.

Over time, additional powers and duties were assigned to the Commissioner, who became the Mining and Lands Commissioner, to make decisions on matters under a number of other statutes, including the Conservation Authorities Act, the Oil, Gas and Salt Resources Act, the Aggregate Resources Act, the Lakes and Rivers Improvement Act, and the Assessment Act.
