The Season 2 finale is called Kali parts 1 & 2 according to the Syfy schedule.

More sort of news on Season 3, whilst in Paris on a promotion tour for Syfy, Amanda Tapping answered a question about a Season 3 for Sanctuary :

"I believe there will, there's a lot of interest so its a matter... because we're sort of an anomaly, we're an independent television show, we don't have a major network or studio backing us so... Syfy has been hugely supportive which has been great but we need, you know, we need to get the financing together so that's, that's  what we deal with every season."

Episode 10 Haunted, the Druitt episode, will be airing in the USA on January 8 but will air in the UK on December 21. For some reason Syfy has switched the airing order of Haunted and Sleepers.

ITV has released an episode synopsis for Haunted and I've included it on the episode page for 2x10 Haunted.
