MGM Resorts International Data Breach – Quebec Class Action

MGM Resorts International Data Breach – Quebec Class Action

Date of Initial Application: June 15, 2020

On August 3, 2022, the Superior Court of Quebec authorized a Quebec Data Breach Class Action against MGM Resorts International in this case.  The authorization judgment is available on this page.


Lex Group Inc. has launched a national Canadian class action against MGM Resorts International regarding the data breach that involved the theft of the personal and/or financial information of approximately 10.6 million MGM Resorts International clients (guests), including clients in Canada. This data breach occurred on or before July 7, 2019 but was only publicly reported on by the media in February 2020.

MGM Resorts International is a Las Vegas (U.S.A.) based company primarily known for managing numerous resorts and hotels in Las Vegas but also in other locations of the United-States and around the world. MGM Resorts International informed a limited number of its clients affected by the data breach by email in August 2019 but sent notices to its Canadian clients only in June 2020.

The stolen information includes without limitation the MGM clients’ names, email addresses, postal address, telephone number and date of birth.

The data breach involves clients having stayed at one of MGM Resorts’ hotels, including but not limited to the following locations:

  • MGM Grand (Las Vegas);
  • Aria (Las Vegas);
  • Bellagio (Las Vegas);
  • Circus Circus (Las Vegas);
  • Excalibur (Las Vegas);
  • Luxor (Las Vegas);
  • Mandalay Bay (Las Vegas);
  • The Mirage (Las Vegas);
  • New York-New York (Las Vegas);
  • Park MGM (Las Vegas);
  • Signature at MGM Grand (Las Vegas);
  • MGM Grand Detroit (Detroit, Michigan);
  • Beau Rivage (Biloxi, Mississippi);
  • Gold Strike Tunica (Tunica, Mississippi);
  • Borgata (Atlantic City, New Jersey);
  • MGM National Harbor (Prince George’s County, Maryland);
  • MGM Springfield (Springfield, Massachusetts).

Accordingly, if you have been a client of MGM Resorts International and if you reside in Canada, your personal information may have been stolen or compromised and you may be part of the proposed Class defined by the class action initiated by our office.

Should you be defined as a member of the class, you may be entitled to compensation should the Court authorize and grant the class action on the merits, or should a settlement be reached (and approved by the Court).

Please fill out the form below if you wish to be kept informed of the progress of this case.

If you wish to be kept informed and/or receive notification of major judgments rendered or notices in this case, please complete the form below.  Please note that providing your information in the form below creates no financial obligation for you and it does not create a lawyer/client relationship between yourself and Lex Group Inc. (or any of its attorneys).  You will not be charged any fees or costs for signing up to this class action since our firm is only paid on a contingency basis from the potential compensation recovered in this file, if the class action is successful by way of final judgment or settlement approved by the Court.

Please be advised that the group definition of the people to be included in this class action may be changed or modified in the future by Court decision or by way of amendment filed by our firm.  We will not inform you or other members of the public if and when the group definition is changed.  It is therefore your sole responsibility to ensure that your own personal rights and recourses are being protected at all times during the course of these proceedings.  You may therefore wish to seek independent legal counsel in order to determine whether it would be in your best interest to pursue independent litigation in this matter (or any other matter), and to determine if you can potentially be included in this case if a final judgment is rendered or if a settlement is reached and approved by the Court.

By signing up to this class action, you are merely asking our firm to include you in our list of potential members in this class action, but our firm is not agreeing to represent your personal interests.  If a final judgment is rendered in this case, or if a settlement is reached (and approved by the Court), an e-mail may be sent to you and the relevant information may be posted on this website.  The Court will determine the manner and extent of any future notifications to class members.

Be advised that the information you provide will be included in our list of potential class members for this case, which list may be shared with and disclosed to the Courts and/or other parties in this action (at our discretion).  Rest assured that any such disclosure will be done in such a manner as to protect your personal information and confidentiality from unauthorized use, disclosure or publication.

Finally, be advised that the above-description and summary of the case is being posted on this website for your convenience.  However, in case of conflict between the information on this website and the actual proceedings, documents, and/or judgments in the Court record of this case, the official Court record documents will prevail.  We have for your convenience posted on this webpage certain scanned copies of the several relevant documents from the Court record, including the initial application for authorization to institute a class action which describes the case in much more detail.  You should therefore consult these documents as well as consult this website periodically in order to be kept informed.
