The predictions of a Conservative majority on the front page are a bit out of date (she says optimistically), but this is a very useful organizing tool: Project Democracy.
Put in a postal code (or click on a map) to see projections for a riding, broken down by party. From there, you can see the projections from all different polls, plus past voting. It's quite an extensive tool.
Many thanks to James for sending, and to Margaret Atwood for tweeting!
