The impact assessment act provides oversight for all projects on federal land, so that would include port lands, and they would be required to undergo a rigorous assessment.
The port authorities would be required to look at whether a project is likely to cause significant environmental impacts. They would need to consider adverse impacts on the rights of indigenous peoples. They would need to consider indigenous traditional knowledge, community knowledge, and public comments as well as mitigation measures that would mitigate any significant adverse environmental effects.
I'm going to ask the president of the Canadian Environmental Assessment Agency to add to that.
