Have they?
I like to think that I'm pretty well connected in the industry, and I have never once heard of CN entertaining the thought of selling the line outside of railfan speculation on forums like this.
There was a "demonstration run" a few years back (more than I may be recalling, but even so...) where CN ran an executive train along the line with a load of local politicians. This was widely reported as a sales pitch indicating CN's willingness to sell the line, and has been remembered ever since. (It may have been an attempt to secure funding, without considering sale, but the train run was more than CN usually expends on pure local goodwill absent an agenda).
Today's position at CN may be different....but....it's all about the purchase price. I'm sure CN realizes that the line is strategically located as a competitor to QEW and a logical GO extension. And looking at their own operation, we don't really know how rates are divided between CN and NS/CSX on the traffic interchanged at the border, or how many car-miles CN earns from that traffic. The traffic may be close to a losing proposition that CN can't shed but may not contribute much to fixed costs. It's not unreasonable to speculate that the line is a) expensive to run and b) not very remunerative, and if that's how CN sees it, there's a plausible connection. But a good theory is not proof.
It should be pointed out that they have been regularly investing in their fixed plant along the line as well, including recently wrapping up a multi-year program to rebuild the lift bridge over the Canal. If they were really so gung-ho on selling it, those are the exact types of costs that they would avoid if they could in order to pass them on to the future owners. They have certainly done exactly that in the past.
You read my mind, sort of. I was about to post a comment about how we don't know where the line sits in CN's capital and life cycle programs. There is aging heavy infrastructure on the line (bridges, etc) that may need a lot of work. It may be a good time to have someone else pay for that work.
So, speculating about CN selling the line has face validity, even if we don't know the management position.
As usual, a big bag of money could change things.
