Alberta's Personal Information Protection Act is a bit clearer than PIPEDA is, but not much. Across the board, even going back to 1990 with the Freedom of Information and Protection of Privacy Act, when it was passed at that time, it had a clearer definition or direction as far as what destruction is and that personal information shall be destroyed when it is discarded, but no definitions of what destruction is, and destruction could be interpreted as many things.
