This is an excerpt from recent legislation in Ontario Canada for 2006.
Restrictions on advertising of certain Internet websites
17.1 No person shall print, publish, distribute, broadcast or telecast an advertisement or representation that includes an Internet gaming business website address unless the person believes in good faith that the Internet gaming business has been licensed or otherwise granted permission to operate in Ontario or Canada by the appropriate authority and is operated in accordance with the applicable laws of Ontario and Canada.

Does this apply to people from outside of Canada/Ontario? I would interpret the first words…..”No person” to encompass anyone and everyone. But will the Canadian mounted police show up at your door on a horse and haul you back to Jail?? I doubt it…..
