Liberal Leadership Convention

When will there be a new Liberal leadership convention? Assuming Harper gets a minority tomorrow, I wonder how long Dion will stay on. Perhaps he'll stay on until the next election. At the AGM, whenever that will be, I assume he needs to get a majority of delegates approving him. It is unclear if he'll be able to get that. Maybe Rae or Iggy will be able to get the Libs out of their funk.
