Okay...fair comment.
Let me go to the general issue here, which is that depreciation or capital cost allowances are supposed to reflect the economic life of an asset.
This is to the folks in Calgary. We as a committee had the opportunity to be in Fort McMurray. We saw some of the equipment. It's pretty impressive equipment, and they're going 24 hours a day, 365 days a year. For that equipment in the oil sands, does that capital cost allowance actually reflect the economic life of that particular asset, and in particular, those big shovels, those big trucks, etc.? Is the industry in fact turning over that equipment once a year?
