I explained my point below in more detail regarding the equation and why I think it should be remembered.

When someone is scanning your system and you haven't authorized it, you will definitively treat it as malicious. In a given moment, you don't care about attacker's inside motives, because your system is under attack and you better act accordingly.

I know a story about a guy who lost his job because of the unauthorized Nessus scanning in his company. Every story with a convicted hacker has some kind of a scanning tool (at least nmap) that was used in scanning phase, you can bet on it. Every scanning tool is an attack tool. In fact, scanners are most useful tools for any kind of attack, because they minimize amount of manual effort needed.

I don't know much about Canadian law, but most current laws forbid unauthorized access and _atempts_ of doing it.
