Thank you.
It is correct that most Criminal Code offences—and the sabotage offence appears in the Criminal Code—are prosecuted by provincial prosecution services. Sabotage in its current form in the Criminal Code is prosecuted currently by provincial prosecution services.
The effect of this amendment would limit the consent for the commencement of a prosecution to the Attorney General of Canada, but does not specify that the ensuing prosecution would be conducted by the Public Prosecution Service of Canada. The effect would be that the consent would have to be provided by the Attorney General of Canada, and the ensuing prosecution in most cases related to matters within the provincial jurisdiction or that are normally prosecuted by provincial prosecutors then would continue to be prosecuted by a provincial prosecution service.
That's my reading of the effect of the provision.
I will also add that in section 2 of the Criminal Code, “Attorney General” is defined as both provincial Attorneys General and the Attorney General of Canada.
