You can check out this page: https://community.canvaslms.com/community/instcon/2016/pages/schedule which has the schedule of all of the sessions (nicely broken down into focus areas). When you log in, you can click yes, no or maybe about the sessions you want to attend. Closer to the start of the conference, I believe that they will have times and locations available for the sessions. (It looks like right now they are trying to see how many people will be at the sessions for space planning). Sessions like the Canvas Roadmap or Mobile Roadmap are almost always at capacity, but well worth it.
Hope this helps!
