Toronto-Montreal cheap one-way travel?

[viaski3]

Train, bus, plane.. doesn't matter. I'm traveling from Toronto to Montreal departure date July 05 or 06, are there any good deals or promos currently out there?

greyhound has a 40% discount if you book 21 days in advance
or a 25% 14 days in advance

it ran me 75ish with tax with a 21 day... plus free wifi so the trip wasn't unproductive!
