Canadian Bill C-22's legal future?
I'm pretty dumbfounded that a supposedly democratic government railroaded Bill C-22 through the house, arguably one of the most dystopian surveillance bills in a civil society.
As I understand it, it will compel companies to retain metadata on all users for at least six months, as well as permit the government to make tech companies install secret backdoors into hardware and software products as requested by the feds. These orders can't be disclosed at all.
My question is what is the legal future of this horrible bill? Many parts of the bill seem to contravene our rights and freedoms (specifically against unreasonable searches and seizures). The secrecy aspect is particularly troubling. How can you even use evidence in a trial if you can't disclose where you got it from? And doesn't prohibiting disclosure impact open justice and infringe on our freedom of speech? On the other hand, how will we challenge Bill C-22 if we don't know what to challenge? In other words, how do we challenge a secret backdoor that gave the government access to my messages, if we don't know that this secret backdoor exists?
Please give it to me bluntly and no need to be warm and fuzzy. The only thing that makes me feel better when I think about this bill is imagining this is going to be a slam dunk to tear this down in court. But I realize it's probably not going to be that simple.
How can a democratic government do this, and will we possibly be able to stop them?
Edit: also, in a practical context how will this bill affect the legal system? For instance, won't we know there's a secret backdoor somewhere as soon as evidence is used in a trial, because the crown/prosecution will have to disclose where and how they obtained their evidence against you? Or will we get into a situation where the government won't "waste" their backdoor by presenting evidence obtained from a backdoor until they get a "big enough" trial?
