I am giving my opinion, but its not altogether uninformed. Im happy to be corrected with facts and citations.
The 7x figure comes from the G&M article I linked. If it's wrong, can someone explain how? And you should probably also inform globe & mail of the error... They will be compelled to correct it, no? Serious question.
With due respect, I know a bit about the industry and the risks. I worked for several maritime organizations auditing and investigating safety systems and incidents. I also worked in the engine room on both deep sea and closer to home vessels. You can go on Gcaptain.com and search "accidents" to give yourself an idea of what happens with disturbing regularity in this industry, in spite of the most ambitious SMS plans and reports. The brand new CG vessel backed into the breakwater just the other day, remember ? That was with a contracted local Master at the controls, similar to a pilot. And from what I hear, was not a systems malfunction...
My opinion: The chances of a spill of recoverable crude are non-zero already with the current tanker traffic. Those odds increase significantly when you add more vessels- except dilbit is not recoverable. It sinks.
If (when) it goes, it goes down to the bottom. What will be the ecological impact of that? Do we even know? The first ENv Assessment didnt look at a single marine impact. Thats how flawed this process has been.
My opinion again: If you like seeing killer whales, or fishing for salmon, or catching crabs in the strait, you may want to get your fill now. Because one "minor" incident during the next 50 years might completely collapse those ecosystems. That is a legitimate risk, and one that we cannot afford.
DNV - a classification society responsible for setting vessel design standards (so they can be insured) - acknowledges the risks. Their mitigation report here is worth reading:

My opinion again: the dollar value cost of a spill is far less important than the ecological cost of a spill. Nobody- not Alberta, not the classification society or insurer, not the shipper, not Justin Trudeau- will pay the true cost of a potential spill.
You and me and everyone who lives here will pay the cost. And it might be realllly bad.
Again, correct me with facts where ive got it wrong, please.
