For governments accustomed to wielding their power to regulate local activity, the Internet has long been a source of frustration. From music sites to Uber to AirBNB, online services represent an enormous challenge to conventional government regulation, which typically relies on a jurisdictional hook to compel compliance. While most reputable global companies can ill-afford to simply ignore laws or court orders, there are still websites that operate largely beyond the reach of government regulation. In response, some governments have attempted to regulate online behaviour, ordering Internet providers to block access to offending websites. My weekly technology law column (Toronto Star version, homepage version) notes that Canadians have generally been spared website blocking initiatives due in part to the Telecommunications Act, which prohibits carriers from controlling "the content or influence the meaning or purpose of telecommunications carried by it for the public." That rule means that Internet providers are effectively prohibited from unilaterally blocking content.
