In order for the act and regulations to be successfully implemented and achieve their original purpose, it is of utmost importance that they contain a good definition of “foreign interference” in various aspects, so that the general public, as well as the enforcement department, can hold foreign agents accountable based upon this.
At the same time, I think public education is also very important. I can look at the reason why Canada has become one of the most badly infiltrated countries by the CCP. There's hardly any meaningful sharing of information from CSIS or the RCMP regarding how Canadians in the general public can protect themselves when certain circumstances happen to them, or how they can report this effectively in a timely manner to the concerned department so that the enforcement department can follow up on it.
It really takes two-way communication to get this act and the regulations effectively implemented.
