Probably the largest ship-source spill that we responded to was the Queen of the North sinking. The other larger spill was the Inlet Drive spill in 2007 in Burnaby, where a backhoe ruptured a pipeline. That was around 100 tonnes.
How do we exercise or practise our capacity to handle larger spills? That is captured in the Canada Shipping Act requirements for a certification program. We do a tabletop exercise for 10,000 tonnes, where we're looking at all our assets and how they're deployed for that specific exercise. That's a two-day program that we run.
