You're thinking of the Fair Credit Reporting Act of the USA which federally regulates credit reporting. In Canada, credit reporting is provincially regulated by the various provincial consumer reporting acts. We don't have reverse onus here, at least, not effectively. You are guilty unless you can prove otherwise - and even then. Read the earlier posts by Footloose and DanielBl on the stuff that goes on for details.
By reverse onus, I mean the onus has been reversed on the consumer to prove that what the bureaus have on file is incorrect; the bureaus' standard of proof is to accept whatever info creditors and collection agencies send them as correct. Obviously, this priority has allowed a lot of abuse to occur by collection agencies and debt buyers through their deliberate misuse of reporting dates and hard inquiries as punitive tools instead of information gathering tools.
