This weekend was the Canadian Grand Prix, and that brought with it a whole host of interesting bits and pieces. From drivers stepping in for other drivers, to a new winner for 2011, to drivers entertaining their guests during the red flag stoppage time. It's all go in Christine's Rankings this week.

Here's how I've handed out the points for the past seven days.
