The current act states that companies—and that includes social networks and search engines—have the obligation to develop procedures. However, there is nothing about the nature of those procedures or the rules that might underlie them. Principle 10 in provision 4.10 of PIPEDA states that it is incumbent upon the companies to create procedures to ensure the respect of substantive rights such as the right to accuracy of information. However, there are no regulations at all and that is a problem.
