McKenzie Lake Lawyers LLP is working cooperatively with a national consortium of lawyers to pursue a class action lawsuit against Monsanto Canada ULC (now Bayer CropScience Inc), Monsanto Company, and Bayer Inc (the “Defendants”) on behalf of all individuals in Canada who (a) had “Significant Exposure” to Roundup® prior to December 8, 2023, and (b) were diagnosed with non-Hodgkin’s lymphoma after their Significant Exposure but before December 8, 2023.
The claim alleges that Significant Exposure to Roundup® products and their active ingredient, glyphosate, is associated with an increased risk of developing non-Hodgkin’s lymphoma. The claim further alleges (1) that the Defendants knew or ought to have known about this increased risk and distributed and sold Roundup® products anyway; (2) that the Defendants misrepresented the safety of their Roundup® products and their active ingredient, glyphosate, to consumers; and, (3) that the Defendants failed to properly, adequately and fairly warn consumers about this increased risk of developing non-Hodgkin’s lymphoma.
For the purposes of this lawsuit, “Roundup®” means any herbicide containing glyphosate that was made, marketed, sold or distributed by the Defendants, even if it was not marketed with the “Roundup®” brand name. It does not include “Roundup® Advanced” herbicides, which do not contain glyphosate.
“Significant Exposure” means the application of glyphosate-based herbicides made, marketed, sold or distributed by the Defendants on more than two occasions in a 12-month period and more than 10 occasions in a lifetime.
