Well, when you read the existing bill, as passed down to us from the House, the subclause in question, subclause 2(4), called the exclusion paragraph, reads: “An electronic message described in subsection (2) or (3) that is sent for the purposes of law enforcement, public safety, the protection of Canada, the conduct of international affairs or the defence of Canada”.
You're proposing to replace “the defence of Canada” with “a body established by an Act of Parliament or a provincial or territorial legislature to regulate a profession, or an affiliated entity of such body”. That's a substantial change to the interpretation clause, clause 2.
