You're right.
The same question seemed reasonable to me in my discussions with my colleagues from the department or security agencies.
There will obviously be prosecutions and criminal prosecutions as the years go on. The courts will properly define the elements of a criminal offence. That's how the law in Canada evolves, and it is entirely appropriate. There are also new tactics. The threat is literally changing month by month, year by year, because of technology.
A definition would have been a way to limit the ability to interfere, but I understand the concern of some if it's not defined. It can go in two directions. I have full confidence in the courts, in the Canadian Charter of Rights and Freedoms and in our national security agencies.
