The only relevant piece of advice here. This is, after all, Canada: if it is indeed CSIS who setup backdoor the OP's computer, there is a paper trail. Lawyers know how to obtain this paper trail. I don't know Canadian law, but the worst I could possibly think of in any of US/UK/AU jurisdiction is that the paper trail says "confidential, pending investigation". I should add that while the malware in question may indeed talking to CSIS servers, this could be the case the CSIS servers themselves are hacked -- more likely by an automated worm in service of spammers (and honestly this is what the 'PG' person sounds like to me -- a scammer/spammer) than any scary entity. Regardless, this is a legal, not technical matter at this point. Get recommendations for a lawyer in your area (you could also try contacting the university staff for this -- they may well be required to help you find an attorney), talk to them. Avoid posting anything else to a public forum.
