I don't think any party will take an active stance on HFR. Very few people outside of forums like this actually know it exists and given other ongoing issues, most would likely not care. The easiest thing to do will probably be to say nothing and quietly wind down HFR and I expect this is the most likely outcome.
It will be more prominent than that. The Liberals will want to take credit for bringing the plan this far (yeah i know, they haven't been all that speedy, but this is electioneering...) and may be willing to promote it in some way (short of a spending blowout) - if not to solve a need, but at least to differentiate themselves from the Cons on willingness to invest on infra, and also on being more green. And woo voters with nice things (the Liberal way, with or without JT).
And if they didn't, the NDP and Greens would seize on it as a Liberal promise unfulfilled.... and point to all the money spent in study, and try to drag out all the data that the government has collected to date and show that the Liberals have been dithering. And because it fits their platform. And - see nice things, above.
How the Cons respond will be interesting The jury is out, personally I wonder if they might offer some de minimus investment in the CN corridor on the premise that they can promise improved trains (doesnt matter if that has validity) at a fraction of the cost. I seriously doubt they will duck the issue altogether.
And even if they did duck, as incoming government they would face the lobbying by the consortia who have built proposals. I bet those business interests (which consist not only of the consortia, but all the trickle down businesses that hope to land sub contracts) seed many all-candidate meetings with questions. Businesses don't owe Pierre any loyalty when their own self interest lies with the project. Same with Conservative candidates in ridings along the corridor, for that matter.
The good news in my view is, the debate is no longer escapable for any of the parties. That's a lot of progress since 2015, even if no shovels have hit the ground.
