Introduction

CA2 serves as Notice Administrator in the V.T. v Aurora Cannabis Inc. & Aurora Cannabis Enterprises Inc. class action before the Ontario Superior Court of Justice.

The Class Action alleges that the Defendants were negligent because they failed to warn consumers, patients and their treating professionals about the risk of developing cannabinoid hyperemesis syndrome (“CHS”) posed by the regular use of their Cannabis Products.

The Class is defined as:

All persons in Canada who purchased a Cannabis Product from one or more of the Defendants on or after February 1, 2014 to the date the order for certification of this action becomes final (the “Class Period”) who were diagnosed or differentially diagnosed with cannabinoid hyperemesis syndrome during the Class Period after consuming one or more Cannabis Products, where “Cannabis Products” or “Cannabis Product” means cannabis and/or synthetic cannabinoid resins, pills, lozenges, concentrates, oils, edibles, beverages, vapours, and raw and adulterated plant material cultivated, designed, manufactured, packaged, labeled, distributed, marketed, and/or sold by the Defendants.

The Ontario Superior Court of Justice (the “Court”) authorized the publication of this notice to let you know that the Court has allowed this action to proceed as a class action, and to tell you that the Class Action may affect your rights.
