If I've understood your question correctly, you're asking whether the information is available, whether it can be made available, through, say, an access to information request. I would say that, generally, yes. Unless there is a particular security element or something, information can be made available.
One of the roles that Health Canada has helped FCSAP with is to communicate risks. The risks associated with a particular contaminate or with groups of contaminates are not always obvious. They can vary greatly depending on the length of exposure or the particular demographic or person, so I think it's just important to keep in mind that communicating responsibly is part of the role of the program and of government. It's to, yes, share and be transparent, but it's also to provide context. Otherwise, things can be more frightening than they actually are, in fact, once there's the proper context.
