Thank you for the question.
I'm not one to use acronyms, but in this case you're talking about PNCIMA. I actually know this process more by its acronym, which is rare for me.
The PNCIMA process is an ongoing one. It's not a decision-making process, but really an information-sharing process, and it will not play a role in deciding whether or not tankers make their way through. There's a regulatory system in place, and those particular questions are strictly in the purview of Transport Canada and its minister.
So I would not be nervous that the PNCIMA process would result in those kinds prescriptive decisions.
