As part of the CITT's process, I can speak to it a bit at a distance, because I'm obviously not involved in that process. Typically they would look at data over a three-year period and look for trends over that period, as well as looking at a more.... In the last finding, they did look at the first half of 2018 and compared it with the first half of 2017 to identify whether there were patterns that showed what looked like a significant increase.
I did mention previously, as well, that you can look not only at whether there's an absolute increase in imports but also at whether there's a relative increase in imports. So if the market's growing, you see something growing or similarly if the market is shrinking, maybe the imports are stable but they're taking up a larger share of the Canadian market.
The data they use is, I think, based on input they are getting from the questionnaires they issue as part of their process, so they could be relying partly on StatsCan information as well as on information supplemented by other participants in the process.
