In Canada, law enforcement agencies ask companies to voluntarily disclose data under the personal information protection and electronic documents act or obtain a warrant. the government has proposed updating the telecommunications lowas to oblige communications service providers to retain data and provide law enforcement agencies with systematic access to communications data. After concerns over expanded government surveillance were raised in the media, the plans were shelved.
