On August 17, 2026, the Commission de coopération environnementale (CCE / ACEUM (Canada–United States–Mexico Agreement)) Secretariat issued a historic affirmative determination (26-2-DET2) requiring a response from the Government of Canada regarding the non-enforcement of its federal environmental laws in the face of Stablex's expansion into Grande Tourbière de Blainville (Great Blainville Peat Bog).
On October 16, 2026, Canada filed its 59-page official response (72-RSP), requesting the procedural closure of the file by invoking the municipal judicial review of Blainville and federal environmental petition No. 0546 (BVG/CEDD). As of October 17, 2026, William Guindon (15 years old, first minor in the history of the SEM process since 1994 to complete these stages) sent his brief of observations demonstrating that no court is examining federal inaction and requesting the creation of a factual file (art. 24.28 ACEUM — deadline of 60 working days).
Next deadlines: November 10, 2026 (mandatory ministerial response to BVG petition no. 0546) and parliamentary meetings in Ottawa in November 2026 with Nadine Le Gal (Office of the leader of the Bloc Québécois) and Senator Madeleine Chenette.

📺 William Guindon — TVBL studio interview (July 2026)
Citizenship, Loi 93 and legal recourse: “The results of this are made to affirm the truth, provide evidence, then have a follow-up. But with this law, we cannot give our citizen point of view. At the UN, it is the right of every person to a healthy, long-term environment for future generations. According to the Charter of Rights and Freedoms, any human can legally express their point of view. In my opinion, it is not normal that it is impossible in Quebec to have legal recourse. »
Operation of the SEM citizen mechanism and federal scope: “For the SEM, basically, it is a process where all citizens and also organizations can undertake an environmental approach when, in their opinion, federal law is not respected. So it doesn't apply to a plant as is, nor to the provincial government, but really to the federal government. It is the federal government that must properly apply its laws. This exchange really allows citizens to tell the truth about what is happening, and then we can choose whether it is confidential or not. In my opinion, it allows us to tell the truth to the world and show that Canada is not perfect. »
Citizen role and responsibility for legal investigation: “In quotes, I do the work that the ministry should do. In my opinion, it is not normal that it becomes a workload for me, when the government has thousands of people who are paid $250 an hour to cite articles of law. I do it for several articles. Then, I have to go deeper to take the steps and provide proof, of course. Then the most difficult point is that I have to prove the legal recourses that fall to the federal government. It’s some in-depth work that needs to be done to prove the truth. Whether the factory complies or not, I just want the truth, that's my goal. »
Approaches to the Federal Ministry of the Environment: “At the Federal Ministry of the Environment, unfortunately, I have had no response. It's a bit disappointing on their part. A person wrote to me on June 28 to say: “Hello William, we will send this to the minister's office, it is at their discretion to answer your questions. » But they must act, they must not wait for the file to come out in the media to make a move. »
Respect for laws, territory and transparency: “I am not asking that the factory close, because in my opinion it is unrealistic, even if it could be possible to a certain extent. But the goal is not to take endless territory for waste. Basically, I just want her to respect the laws and for us to stop claiming that everything is correct. It is not normal to always tell citizens “everything is perfect, everything is correct”. Give us proof, because without proof, we cannot believe you, and citizens begin to lack confidence. »
🎬 William Guindon — Official video capsule & Social networks (October 2026)
Alert on the October 16 deadline and quest for truth: “The Government of Canada has until October 16 to explain itself in an international investigation. My goal is just to get the truth. »
Intergenerational equity and fish habitat (222 technical evidence): “If I understand correctly, there were a lot of words in your question. The principle of intergenerational equity, quoting: "it is important to meet the needs of the present generation without compromising the ability of future generations to meet their own needs", is also federal. Concerning fish habitat, I documented this inaction with 222 technical evidence and submitted the case to CCE, the official arbiter responsible for enforcing environmental laws. »
Historical determination and Ottawa's legal obligation: “The result is a historic determination. The international secretariat judged my citizen survey. Ottawa is now legally obligated to respond by October 16. The entire file is on my website. Share this video en masse to follow the rest. »

💧 Dr Sonja Behmel (Water Specialist and Researcher, WaterShed Monitoring)
Contaminant Migration and Wetland Value: “There are areas where we are virtually certain that contaminants are leaving the site, either by air, groundwater or surface water runoff. Wetlands are our most valuable source of biodiversity. To make sure we have them when heavy rains bring flooding risks, and for areas that put water back into the environment in times of drought, and for ecosystems that filter out our contaminants, it's like we're destroying ourselves. »
Citizen concerns and environmental governance: “I have the impression that the people of Blainville are extremely worried and that they want answers. I think that beyond wanting answers, my feeling is that they really want the government to comply with the mechanisms that it is supposed to put in place. We know we need industry, we need places where we can dispose of our waste and everything else, but it should be done according to the governance mechanisms, and we should respect them at every step, because otherwise we will destroy our environment. »
🏛️ Jorge Daniel Taillant (outgoing Executive Director of CCE / ACEUM)
Binding force of the treaty and integrity of the ACEUM: “It was a surprise, at first we said to ourselves, well, maybe it's a mistake, maybe we shouldn't be on this list, and the more we look, maybe it was a mistake. We are treaty based. We are part of ACEUM. One cannot withdraw or cease participation in part of the treaty without undermining the entire treaty. »
Tripartite funding context and transition: “We have not received new funds from the United States for 2026, which has created problems because without funding the CCE cannot function. Canada and Mexico, while remaining committed to CCE, have also suspended their financial support. We are in a period of transition, awaiting clarification on how this will unfold. »
Ecological emergency and power of citizen action: “The most important things are the challenges we face today, the urgency of fighting climate change and the urgency of what is perhaps the sixth extinction of biodiversity which is taking place before our eyes. People want to know, want to get involved and have more say than ever in their environment. The survival of CCE is essential to our cooperative work, but more importantly, public policies must be attentive to communities, and communities will increasingly demand action. »
⚖️ Paolo Solano (Director of Legal Affairs of CCE)
Operation and resources of the legal unit: “Last year we had a team of four people; a staff member left. Structurally, there is a position for someone else, but in the current circumstances we are not hiring more; It's a question of budget. »
