Presuably to counteract the effects of the Information and Privacy Commissioner's decision that bans siping licenses at bars in the province (Alberta Commissioner forbids license scanning), the Alberta legislature is considering Bill 42 which permits the collection of similar information:
Legislative Assembly of Alberta - Bill 42: Gaming and Liquor Amendment Act, 2009
Collection of personal information by licensee
69.2(1) A licensee may, before allowing a person to enter licensed premises, collect the person’s name, age and photograph.
(2) If a licensee has personal knowledge or reasonably believes that a person referred to in subsection (1) has, at any time within the preceding year, engaged in an activity referred to in section 69(1) or (2), the licensee may, in good faith, disclose the person’s name, age and photograph to other licensees for the purpose of allowing them to determine whether they wish to allow the person to enter licensed premises.
(3) A licensee must, as soon as possible after a request is made by a police officer, disclose to the police officer any information collected under subsection (1).
