Here's their conclusion :
"The Agency concludes that, taking into account the implementation of mitigation measures, the Project is not likely to cause significant adverse environmental effects as defined in CEAA 2012.
The Agency has identified key mitigation measures and follow-up program measures for consideration by the Minister of Environment and Climate Change in establishing conditions as part of the Environmental Assessment Decision Statement, in the event that the Project is permitted to proceed.
In addition, it is the Agency’s expectation that for the Project to be carried out in a careful and precautionary manner, all of the proponent’s commitments, as outlined in the Environmental Impact Statement and its supporting documents, including the document titled “Addendum to the Environmental Impact Statement - Mitigation, Monitoring and Commitment List” and available on the Canadian Environmental Assessment Registry’s Internet Site, would be implemented as proposed."
