Lawful access was a contentious issue on the Canadian agenda when it was initially introduced by the Martin government, and has become even more disputed as subsequent governments have introduced their own iterations of the Liberal legislation. Last year the current majority government introduced Bill C-30, the Protecting Children from Internet Predators Act. In the face of public outcry the government sent the bill to committee prior to a vote on second reading, and most recently declared the bill dead.
