3-Your client, J.W. Hart, president, and CEO of Hart Industries Inc., is having a party to which both adults and children will be invited. The client intends to serve champagne and would like to serve not only the adults but the older children (the 17-and 18-year-olds), too, with their parent's permission. The legal drinking age in Ontario is 19. The client wouldn't be consulting you if the party was being held in his own home, but he's concerned because the party is being held in a big tent on the grounds of a well-known public garden. A large area around the tent will be roped off to keep out uninvited people. Can the client legally serve wine to anyone under 19 at the party? Explain, quoting the relevant statute and regulation.
