Unwanted or fraudulent calls: how to block them

Recognizing a suspicious or fraudulent call

Some calls may seem legitimate. Here are some signs to look out for:

urgent or threatening call
a request for personal information
pressure to act quickly
unknown or unusual number

If you're unsure or have already interacted with a call, see the steps to follow in the event of fraud.

Blocking or screening calls

The options for blocking or screening calls vary by device. If you receive suspicious calls, you can block them or turn on screening options to reduce their frequency.

Select your device to see the steps to follow:

Good to know

Calls from blocked numbers will no longer ring and may be sent to your voicemail or appear in your call history, depending on your device.

Home phone

On your home phone, you can block unwanted calls, including from anonymous numbers. Options such as Call Screening, Anonymous Call Rejection, and Call Trace allow you to significantly reduce unwanted calls.

Learn more about these options for screening incoming calls.

Another option is to purchase a call blocker. This type of device connects to a landline phone and blocks robocalls, calls from unknown international numbers, and calls from known telemarketers.

Automatic screening (network)

Telecommunications companies block some calls from non-compliant numbers, which is a first barrier of protection.

However, it is not possible to block all unwanted or fraudulent calls, as fraudsters regularly find new ways to circumvent these measures.

Limiting telemarketing calls

Telemarketing calls are different from fraudulent calls.

Telemarketing calls usually come from companies that want to offer you a product or service. Fraudulent calls, on the other hand, are made with the aim of obtaining your personal information or deceiving you.

If you repeatedly receive telemarketing calls, here’s what you can do to reduce them:

Register with the National Do Not Call List (DNCL) to stop receiving calls from most telemarketing companies.
Register to the Videotron Do-not-call List to avoid receiving calls from Videotron or to exclude yourself from one of our communication methods. Manage your communication preferences in the Customer Centre.
Note the date and time of the calls, as well as the phone numbers that are displayed. If you don’t have Call Display, dial *69 to get the last caller’s number. 
If the problem persists, contact Technical Support, as needed.

If you have a fax machine and Call Display, you can send a fax asking the caller (sender) to stop calling you.
