Let's not get too paranoid.
While it is true that you can be charged with using anything for a weapon if you don't really need it, it is also true that you are perfectly entitled to use force, even lethal force, to protect yourself from harm in Canada.
I think the laws regarding self protection (not the gun laws) are quite reasonable. You must be facing a legitimate threat to persons, not property. You must use only that force necessary to negate the threat. That means, once you no longer fear for your safety, you must stop. But the truth is, there are several cases in Canadian law where people used lethal force and were ruled to have been justified.
I suspect, however, that if 2K met an intruder in that outfit, he would be hard pressed to prove he couldn't possibly have had time to try something else. As much fun as it would be, I think you need to appear just a little less premeditated.
