Martin might want to comment as well.
Mr. Arseneault, the drafting here is on the advice of the Department of Justice, which, in the creation of these powers, always expresses it in terms of permission. CBSA has, by virtue of proposed subsection 92(1), the authority to collect. The precise details, as per Monsieur Dubé's question in terms of the modalities of that collection, will be laid out in regulations, and that is also a public process that brings with it due scrutiny.
The choice of the word “may” is the best considered advice of the Department of Justice that this is the proper way to give the agency the authority it requires to take the actions that are laid out in Bill C-21.
