It's enforceable in two ways. One, granting police the same level of intelligence gathering and universal surveillance techniques granted to CSIS or making CSIS do it.
Two, and the most likely, deputize all citizens to report all instances of suspicious behavior to the local police, possibly providing incentives to do so, creating a network of trusted informants. If this sounds familiar, it should, we've seen it played out a few times in history.
In both cases we are creating the classic problem with Big Brother. If all illegal or unlawful acts are observed, the police may choose to either enforce all of them, none of them, or more likely, enforce them arbitrarily. This allows the suppression of "problem elements."
Obviously this is not the intent of this bill, but as history has proven, Intent is Irrelevant. All that matters is what the bill states.
