There are definite risks with this language. In part, it's a cumulative effect. We already have a requirement that the use of this authority needs to be reasonable in relation to the gravity of the threat. That already specifies that the use of the power needs to be commensurate with the level of the threat, so it can't be used for no good reason or for trivial reasons or anything like that, given the nature of the power itself.
The word “systemic” is not defined or is not a technical term that is familiar. Given that the phrase “telecommunications system” is existing language, which this is a novel variant of, it appears that it could imply that only an attack on the entire system is what the power could be used for. An attack on an individual service provider could still affect millions of Canadians.
