It's because we've seen this grain crisis and the impacts it's had on farmers. We've heard testimony about how people would like something that is more long-term to guarantee that this will not happen again. We would like to have that part of the piece repealed to make sure this does not happen again, so that there is more long-term assurance that this problem will not be reproduced. It's to make sure that it is in fact a long-term solution and not something that will sunset after two years.
