The Ottawa Genealogical Society has put a note on it's site at http://ogsottawa.on.ca/ that they will not hold a Gene-O-Rama in 2012. The reason is because the Ottawa Branch will be co-hosting the annual OGS Conference 2012 in Kingston on 1-3 June 2012.
They also say that "Ottawa Branch will also be hosting the 2012 Region VIII Genealogy Day. It’s on a smaller scale with three lectures, the Regional Annual General Meeting and a small Marketplace on a Saturday in March or April 2012. We’ll start planning it later this year and details will be available on the website."
