A lot of news and online users are talking about the political timeline/nature of it but this is a culmination of a years-long project phase. It's not a pie-in-the-sky campaign pledge that Trudeau dreamed up on the back of a napkin (like Ford's 401 tunnel). Though it is still at a stage it can still be shut down and we'll be back to square one again.
It should be obvious that because the government is prorogued, Trudeau cannot go out and commit funds to these projects if they were not already approved during his term.
Maybe people don't see the link because of the sudden branding change, but this is what became of what was originally the High Frequency Rail proposal. The three consortiums passing the Request for Qualifications were tasked to propose a solution weighed what speeds the trains should go at. High-frequency without being competitive with driving and flying would not spur that much demand. Note that hfr-tgf.ca now redirects to altotrain.ca.
This consternation is a bit infuriating to me. With the mindset of the timing always being too "political", no big project that is over 4-5 years in timeline is ever going to get done. I would like to see the three proposals publicly released so it can be proved that options were presented based on things asked far before this campaign, and the most sound option was selected.
