If there is a first rule of the Internet in Canada, it is "thou shall not block." Canadian Internet service providers face a wide range of policies that have implications for accessing content including net neutrality rules and the copyright notice-and-notice system. Yet in virtually all cases, blocking or removing content is simply not done (the lone exception is a limited, private sector led initiative to block child pornography images). My weekly technology law column (Toronto Star version, homepage version) notes that unlike other countries which have dabbled in mandated takedowns or Internet filtering, Canada has largely defended an "open Internet". Canadian law does not mandate that Internet providers take down content due to unproven allegations of copyright infringement or allow them to alter or change content. In fact, the Telecommunications Act stipulates that "a Canadian carrier shall not control the content or influence the meaning or purpose of telecommunications carried by it for the public."
