That answers my question

Apparently it’s Chevron, not BP, that has been seeping oil from a Burnaby refinery into the Burrard Inlet for the past month without really telling anyone.

And I guess its not really clear what the Conservatives really think about offshore drilling. I think Prentice wants to sound like moratoriums exist (at least in the Arctic) but doesn’t really want to rule out any drilling once the fuss over a little spilt oil subsides.
