Thanks.
We did two things.
We did some modelling a couple of years ago on the overall impacts of the carbon price as best we could, and those are on our website.
In the specific case of grain drying, we've done some internal modelling, but the results that are quoted come from submissions from a number of groups: the Grain Farmers of Ontario, Keystone Agricultural Producers in Manitoba, APAS in Saskatchewan and the Government of Alberta. The estimates are slightly different, and that's why we came up with a range. It's grain farmers. There's no broader number of farms included there.
