Call Trace (*57)
The Call Trace service allows you to alert authorities against threatening or harassing telephone calls by tracing callers, even if they conceal their identity.
You must be prepared to contact the police so they can investigate. According to regulations, Videotron cannot provide you with this information.
Note: A $6 fee (up to a $12 limit) will be charged each time you use this service, even if you don't call the police.
