In 2021, the province of Ontario changed the name and created guidance for Regulation 240/00 of the Mining Act: Advanced exploration, mine development and closure. These changes clarify closure plan requirements demonstrating that the requirements through the mining sequence are gradual, scalable and proportional to the activities and impacts associated with each project. These changes help to build a competitive regulatory framework for all minerals, including critical minerals.

The regulation provides guidance on improving transparency in mining development through public notice. The regulation also established a mandatory consultation process with Aboriginal communities before submitting closure plans or amendments related to mining activities. Proponents must notify the Director, conduct consultations as directed and follow written directions that may include preparing a proposed plan, submitting consultation reports and providing interim reports. Additionally, the act outlines a dispute resolution process for conflicts related to Aboriginal consultation, involving referral to a designated individual or body for facilitating consultation and providing non-appeal recommendations to the Minister.

The life of a mine begins on the date that the mining closure plan is filed or deemed to be filed. Section 24 of the Regulation lists the minimum rehabilitative measures that must be taken upon mine closure. Technical specifications for mine closure are detailed in Schedule 1: Mine Rehabilitation Code of Ontario under the following categories:

Part 1: Protection of mine openings to surface

Part 2: Open pits

Part 3: Stability of crown pillar and room and pillar operations

Part 4: Tailings dams and other containment structures

Part 5: Surface water monitoring

Part 6: Groundwater monitoring

Part 7: Metal leaching and acid rock drainage requirements

Part 8: Physical stability monitoring

Part 9: Revegetation

Big Oil Eyes Record Profits but Keeps Spending in Check

Oil supermajors have been raking it in since the war in the Middle East began. They are now set to report another robust quarter, even as some jurisdictions where they operate plan to slap windfall taxes on them. The question now is what Big Oil will do with these profits. The answer: it probably won’t be a spending spree. They sure have the money for a spree. If the second quarter is any indication—and it is—oil and gas majors are having a really strong year. Out of all S&P 500 sectors, Energy booked annual growth of 128.2%…
