The Department of Human Resources and Social Development has been collecting these data going back to the early 1970s. We collect data on the number of work days lost, the number of strikes, wage settlements, and all that. These are data that we have been collecting for more than 20 years on the same technical basis as Statistics Canada collects all of their data. These data have been public, and they're available to everybody, and they've been used by many analysts.
