We are exporters of potash, and we are the largest producers of potash in the world. We have the most significant reserves in the world. As I mentioned, we also produce it in the most sustainable fashion, so we should be the most desired producer and seller of potash in the world. The vast majority of potash that we produce is for external markets. Obviously, there are big markets in Canada, but the majority of it is for export.
It's important to understand that we also import about 50% of the fertilizer that we need for farms across Canada; it is imported because we don't produce any phosphate fertilizer in Canada. This is all imported. We still import a great deal of nitrogen fertilizer, especially to the east coast. We've even imported, in the past, potash to the east coast because of the cost of transportation. Right now, we have a tariff on Russian potash, so there is not a lot of Russian potash coming into Canada. It's being supplied mostly domestically. Because of that situation, it's very important for us to have open trade. It's important for every farmer in Canada, as we are seeing.
I raised the war in Iran because it's an example of how something that happens globally can impact the availability and the price of fertilizer in Canada. For this spring, there doesn't seem to be any kind of problem with the supply of fertilizer in Canada, even nitrogen-based fertilizer, a great deal of which is produced in the Middle East. However, next year, depending on what happens with this war, it could be a different situation.
