Again, some of these details will be worked out as part of the regulations.
Right now, under the provisions of Bill C-49 the information gathered as part of random sampling or resulting from an incident or accident investigation conducted by the railway company may not be used for disciplinary purposes, competence, or for judicial proceedings unless it involved tampering with the equipment or there were a threat to safety determined as part of that sampling.
What constitutes a threat to safety remains to be determined under the regulations. This is why we are emphasizing that those regulations and the powers of enforcement have to be strong to make sure there's not inappropriate use or misuse of the data by those who have access to it.
