And The Last Ship, or at least it was during the first two seasons. Haven't had to watch the current one online yet, though the commercials do indicate you can watch it online. I would be very surprised if Dark Matter wasn't also. I don't watch that show, so I don't know for certain.Only Killjoys and Dr. Who.
But I would be very surprised if Discovery wasn't available to watch on their websites. That's kind of a bog standard for all shows on any channel, as it allows those who can't catch it on TV to watch it in a manner which still supports the channel. If Space really isn't going to have this show on their website, they're giving the middle-finger to anyone who can't watch the show live and encouraging the audience to consider alternatives.
Crave having exclusive streaming rights is not the same thing as Space won't have the show online. Presumably the hook for Crave is that you don't have to put up with commercial breaks and can watch the season whole, since they're waiting until after its done. When Space has episodes online, they still have commercial breaks (which are rigged so you can't fast-forward through them) and the episodes only stay available for a few weeks.
