The Aggregate Resources Act requires you to rehabilitate your pit or quarry during its operational lifetime.

You need to rehabilitate the parts of your site which you’ve completed work on, while you continue extracting aggregates in other areas. These areas can be rehabilitated into wetlands and habitat for wildlife, farmland, parks, fruit orchards, vineyards, subdivisions, golf courses and recreational fishing areas.

Most changes to site plans, which includes plans for rehabilitation, requires approval from the Ministry of Natural Resources.
