Propecia and Proscar
The class action seeks to compensate every person who suffered an injury following the use of Propecia or Proscar (scientifically known as finasteride) for the treatment of male pattern hair loss.
The motion alleges the liability of Merck Canada and Merck Frosst Canada due to the fact that they promoted their medication as a treatment for male pattern hair loss while they were aware, or should have been aware, that their product warnings regarding side effects were inadequate.
On March 28, 2019, the Supreme Court of Canada dismissed Merck Canada and Merck Frosst Canada’s application for leave to appeal. This decision confirms the judgment of the Quebec Court of Appeal authorizing the class action against Merck Canada and Merck Frosst Canada in this matter.
The authorization of the class action means that Mr. Baratto and its lawyers will represent all class members in the class action.
The Honourable Christine Baudouin of the Superior Court was appointed to hear the case.

The Class Action
In April 2013, Mr. Baratto filed a motion seeking authorization to institute a class action (the “motion seeking authorization”) against Merck Canada Inc. and Merck Frosst Canada & co.
On December 21st, 2016, the Honourable Claude Dallaire dismissed the application for leave to institute a class action against Merck Canada and Merck Frosst Canada, which was argued on January 27 and 28, 2016.
Your representative Camilo Baratto and we, your prosecutors, have decided to appeal this judgment, which, in our view, contains several errors of fact and of law. The hearing at the Quebec Court of Appeal was held on January 23, 2018.
On July 26, 2018, in a unanimous judgment, the Quebec Court of Appeal authorized the class action.
On October 1, 2018, Merk Canada and Merk Frosst Canada applied to the Supreme Court of Canada for leave to appeal the judgment of the Quebec Court of Appeal granting authorization.
On March 28, 2019, the Supreme Court of Canada dismissed Merck Canada and Merck Frosst Canada’s application for leave to appeal.
