I've read and re-read that article, it's interesting, but I can't find where it states your claim. Could you copy and paste it in?
Nothing here either:

I do believe it is inevitable that CP comes to a pending agreement on The Link, but it might be a month or so until we read something more definitive on it.
Let's flip this over for the sake of argument, ditto with Brampton extra tracks: Suppose there are discussions going on right now on the Missing Link, serious ones, and perhaps not even going smoothly in some respects, but the Feds (the only ones with the legal hammer to swing on this, as well as the cash to sweeten it), won't be proposing steps that will suddenly become redundant when the Link becomes extant. Time taken to build the Link? Roughly the same as doing the otherwise necessary improvements on the K/W and Milton lines. There's not much time to be lost by waiting a little longer and getting this right.
I may be wrong, but there might me method to the madness we're seeing on this. What we're reading today (and the next few days) are 'appetizers' for the real meal. We might have to wait even months yet, but the appetizers are served to keep the patrons entertained before the really big ones are announced. And the Feds are talking multi-Billions$ over the next ten years in terms of investment, and that's their money (our taxes) alone. Some $30B (IIRC) is to be used for seed money in the Investment Bank. Apply the leverage ration of 4:1, and that's $150B, mostly for "transportation".
Also bear in mind that the Feds need to show "bargaining in good faith" to potential investors in terms of 'priming the investments' for a more specific large project to be easier to define and negotiate as a result of many smaller steps.
Keep your fingers crossed, and enjoy those appetizers. I think the movie is about to start.
