RE:RE:http://www.mrn.gouv.qc.ca/english/publications/mines/environWhile a nice thought that HQ may influence the decision. The determining factor will be the plan and the ultimate responsibility of the civil servants working to approve that plan. If I were you I would count on a minimum of 8 months for approval. The time frame will depend on the details included in the original submission and the number of questions the Ministry has. These plans are never approved at cabinet level, the politicians rely on the experts and take their advice.
