The route from NY up to Montreal that veers into Vermont for a bit may happen eventually but in the much nearer future there is a plan to extend the Vermonter from its current terminus in St. Albans up to Montreal. It's not high speed but it is happening.

Also for NH there is a chance of the Lowell Line extending up to just outside of Nashua NH soon and it could in the future follow that existing rail line up to Concord and with enough upgrades a Boston to Montreal route could exist running diagonally up through NH/VT with stops likely in Manchester, Concord, White River Jct., Montpelier, and Burlington. This would provide service to the state capitals and largest city of each state. The stop at White River Jct. I suggest because the tracks in the area all have rather sharp turns that would be prohibitively expensive or even impossible to straighten because of the hills, rivers, and existing development in the area. This would be a very expensive route to upgrade to high speed rail particularly while it crosses the mountains in NH and VT, but if it were created it would likely be a highly competitive and successful route.
