It is illegal to intercept a private communications unless authorized by the Code (e.g. with a warrant or as part of maintaining the communications system) or unless the consent of one of the parties is obtained.
A lawful party to a call that starts and ends in Canada can record that call if they are doing so for a personal or journalistic reason and not a commercial purpose. If recording is to be carried out in connection with a commercial activity, check out “Focus on Privacy – Call Monitoring“.
