Okay.
We don't see any immediate volatility due to carbon pricing in Canada. In fact, if you look at months when the tax actually goes up—so in April, May and June—there's actually little volatility, so we don't see evidence of that. However, like I said, over time, over several years, we could actually force companies to see their costs increase and become less competitive. Because we do have access to firm-level data—we can't share that, unfortunately, for obvious reasons—we do see that some companies struggle financially a lot more because of the low margins.
You're referring to the petroleum industry. Margins there, as I'm sure you know, are much more significant than in the food industry. From farm gate to plate, margins are extremely low, so the carbon-pricing policy can have a huge impact on an industry where margins are incredibly slim.
