We encourage you to submit your comments. During the comment period, a link will be added in the comments column directing participants to a survey. The Technical Advisory Board (TAB) will review and consider all comments and proposed changes. Based on participants' input, modifications may be made to the Part B to which a proposal was made and/or to improve Part A. In the future, should a Part B require additional rules, this same process can be implemented and the Part B updated. We also encourage comments to be submitted outside of the official consultation period. Download the PCR comments template >
