On December 11th 2000, following the announcement of the water table contamination feeding private wells, mostly on the south-east side of the Jacques-Cartier river in the municipality of Shannon, talks were already brewing to create a defence committee. On February 14th 2001, the Shannon Citizens’ Committee was formed. The aims of this Committee were and still are to inform and defend the Citizens who are suffering or have suffered in the dossier of the contamination by TCE and its degradation products (MCE (CV ou VC), DCE et PCE).

In December 2003, the Committee notified its intention to sue (as a class action) the liable organisations for the contamination. From January to November 2011, we were in Superior Court with a verdict rendered in the summer of 2012. Following our reading and analysis of this 2012 judgment and our conviction of errors of law and fact and mixed errors, this judgment was carried in Québec Court of Appeal. The appeal was heard, pleaded and questioned on the weeks of 22nd and 29th of October 2018 for 8,5 days. The judges’ decision is expected in a future going to several months following this audition of the Appeal.

If you believe that you are suffering or have suffered or if you know of a person suffering or that as suffered of this situation, the Committee invites you to fill out the online form describing your situation or the situation of another person. The aim of this form is to obtain the most complete register of the cancers and other medical situations that could have a link with the TCE contamination. All information on the form will be confidentially treated by the Committee, our lawyers and experts.

This form describing medical situations is not a registration for the Class Action. We cannot presume the outcome of the Appeal’s Court judgement, so, all affected Citizens and former Citizens, already registered or not, must wait for the Appeal’s Court judgement to know the events that will follow. Whether you have joined or not the Class Action, a period of registration could follow after and according to the declarations that will be in the judgement of the Appeal’s Court. Instructions will follow.

On the other hand, to help you complete the descriptive questionnaire of your medical situation, here is a situation in the United States. In an American law, “The Janey Ensminger Act of 2016”, eight medical situations were recognized by the US government as having possible links to TCE contamination. Here is an enumeration :


(1) Kidney cancer

(2) Liver cancer

(3) Non-Hodgkin’s lymphoma

(4) Adult leukemia

(5) Multiple myeloma

(6) Parkinson’s disease

(7) Aplastic anemia and other myelodysplastic syndromes

(8) Bladder cancer

The Committee adds to this list a 9th and 10th case, a brain cancer and a male breast cancer.

(9) Brain cancer

(10) Male breast cancer

It is to be noted that a medical situation or cancer that you want to describe is not restricted to the 10 cases listed. From time to time, the Committee will publish historical and actual information “here” on this site, but also at the following addresses (URL) :
