THOMSON, ROGERS has issued a national Class Action lawsuit on behalf of Canadians with Parkinson's disease and/or Restless Leg Syndrome who allege to have developed compulsive behaviour, including a pathological gambling addiction, as a result of their use of the drug Mirapex, a dopamine agonist. The Class Action claim seeks millions of dollars in compensation from the Canadian drug manufacturer, Boehringer Ingelheim (Canada) Ltd., and two American corporations.

Please note that anyone who started taking Mirapex AFTER July 27, 2012 is not eligible to participate in the class action (as they do not fall within the Court approved definition of a 'class member')--those persons may wish to consult with a lawyer in relation to any claims they may have.


The tentative Settlement Agreement will be considered for approval by the Ontario Superior Court of Justice at 10:00am on February 18, 2015 at Osgoode Hall, 130 Queen Street West, Toronto.

If you have already submitted a completed Questionnaire as part of the Negotiation Process, you do not need to do anything further.  A letter will be coming to you shortly with respect to your individual claim. 

If you are a Class Member and have not submitted a Questionnaire then, as set out in the Settlement Notice, along with the required Doctor's Letter you must do so prior to December 10, 2014 in order to be considered for compensation.  If you fail to submit a Questionnaire by the deadline, you will be forever disentitled from making a claim for compensation (note that there is no guarantee that submitting a Questionnaire will result in any compensation).

Thomson, Rogers is pleased to advise that a tentative settlement has been reached in this class action. 

As this is a certified class action, any settlement proposal must first be approved by the Court.  Accordingly, we are now working diligently to formalize an agreement which will be submitted to the Court for approval.  More information will be provided on this website as soon as possible. 

We know that you are anxious to learn the details about any possible settlement and, just as importantly, discover when the Court might consider approval and allow the release of settlement monies to eligible claimants. 

Here is what we can tell you now: 

  1. The proposed settlement contemplates payments only to persons who began using Mirapex prior to January 1, 2007 (on the basis that warning information had been circulated and was generally available by then).
  2. Persons can expect to recover a fraction of documented losses directly related to compulsive gambling.  The numbers will vary depending on new claims coming forward.
  1. Those who suffered life impacts from gambling and persons who suffered from other compulsions (hyper sexuality, binge eating and excessive shopping) will be entitled to compensation for pain and suffering in relatively modest amounts, reflecting the many issues associated with proof and causation. 
  1. Direction from the Court will be sought so that a formal Notice can be circulated hopefully in the fall of 2014.
  1. An Administrator will be appointed to assist in making final decisions regarding a claimant’s compensation.
  2. A letter will be sent to all claimants who have provided materials to our offices providing further details as soon as those details are available. 
  3. Subject to the Court’s availability, we are hoping to have a Court review the settlement near the end of 2014 (or in early 2015) with settlement funds paid out thereafter (our best estimate would be that funds could be available in the spring of 2015 if the Court approves the settlement in a timely way).
An update regarding the outcome of the mediation in June of 2014 will be posted here within the next few weeks. Please wait patiently for that update.
A mediation in this matter has now been scheduled to take place on June 24 and June 25, 2014. We anticipate being able to provide information regarding the outcome of the mediation in early July.

The parties will be meeting near the end of November, 2013 to discuss these claims. A further update will follow thereafter.

The deadline for the submission of Questionnaires under the Negotiation Process has now past.

We are in the process of sharing the information that has been received from class members with the lawyers for the defendant.

We expect to have meetings with the defence lawyers over the next several months to discuss the possibility of a negotiated resolution.

We intend to send an update letter to class members at the end of August, 2013 and ask that you wait for our letter rather than call for updates.

We will also post any public update information here as well.


We are pleased to announce the Certification of the Mirapex class action by Order of the Honourable Justice Strathy dated July 27, 2012.

To review the official Certification Notice please click here.

We are also pleased to announce the agreement between the parties to develop a Negotiation Process aimed at determining whether the claims of Class Members can potentially be resolved without further litigation.

If you are a person resident in Canada (other than Quebec) who was prescribed and ingested the drug Mirapex prior to July 27, 2012 (a "Class Member") and claim, as a result, to have suffered damages relating to an impulse control disorder (meaning pathological gambling, hyper-sexuality, compulsive shopping and/or binge eating) we strongly encourage you to participate in the Negotiation Process.

To participate in the Negotiation Process, you must submit a completed Negotiation Process Questionnaire to Thomson, Rogers, by Wednesday, February 27, 2013.

Below you will find the following important documents:

  1. Order of Justice Strathy dated July 27, 2012
