If you look at a mushroom farm, basically we have a super structure. The super structure is four inches thick with insulation. Within the super structure we'll have all the growing rooms, and those growing rooms are another four inches of insulation in each room, so they're very well insulated to try to mitigate extra costs. The problem we have is basically the fresh air that's needed. Come winter, we have to bring the outside air temperature up to about 14°C or 15°C. Here in Ottawa, we have winters of -30°C, so I have to take the -30°C fresh air coming in and bring it up to +15°C. That's huge.
About three years ago, my brother and I invested in basically bringing our own natural gas into our facility, which cost us almost $2 million. We were on propane before. Propane isn't as efficient as natural gas. We did that to sustain our future, basically.
We've also changed our routes of delivery, so we deliver four times a week to our retailers versus the traditional six times a week, which saves about 20,000 kilometres per vehicle, so that's another 100,000 kilometres saved to help mitigate the use of fossil fuels.
We're trying our best to do that. The figure I gave earlier was just the carbon tax we're paying on our natural gas and diesel—coloured diesel. All our input costs have gone up, and some of our suppliers have said—
