Yes. Under the Mining Act, all mining companies are required to place the necessary funds to cover rehabilitation and restoration work in trust within the two years following the date of approval of the rehabilitation and restoration plan by the Ministère de l’Énergie et des Ressources Naturelles [Québec department of energy and natural resources] (50% within the 90 days following allocation of the funds, then 25% on the first anniversary and the remaining 25% on the second anniversary of allocation). The rehabilitation and restoration plan must be approved before construction begins.
