Quebec's access to information legislation does indeed set out restrictions protecting the information provided by third parties and private enterprises under certain conditions. If the disclosure is likely to reduce the enterprise's competitive margin or result in profit for a competitor or third party, a person can request access to the document provided that it is held by a public body that entered into a contract with a private enterprise. But the public body can check with the enterprise to see if it consents to the disclosure in question. If not, the public body can invoke those restrictions, and it will be up to the third party or private enterprise to show that it can refuse to grant access to the document under the restriction conditions. The enterprise must demonstrate that to the commission.
