Deadline Monday April 11 to apply to be an “intervenor” in the CNSC hearing for the giant Ottawa River nuclear waste dump

Note: If you are seeing this page for the first time and the April 11 deadline has passed, feel free to write to the CNSC to tell them what you think, and copy your Member of Parliament.

On April 1 the Algonquins of Barriere Lake joined the Kebaowek Algonquins and numerous elected officials and civil society groups in calling for a halt to the licensing hearings for the giant Chalk River/Ottawa River nuclear waste dump .

Unfortunately, the requests are falling on deaf ears as Canada has a woefully inadequate nuclear governance system that leaves the Canadian Nuclear Safety Commission free to steamroll ahead with licensing in defiance of common sense and the wishes of many Canadians and Indigenous communities. 

Please consider adding your voice to the many who are calling for a halt to the licensing of the giant, million tonne radioactive landfill, called NSDF by the proponent. You can “intervene” in the CNSC hearings that start on May 31 either by sending written comments or by making an oral presentation to the panel of the commision. Whether you choose to intervene with a written submission or an oral presentation, you need to apply by April 11.  It’s a simple process. See below for details.

5. Please cc your Member of Parliament on your request to intervene.

There is a ton of substantive material on why the case to approve the giant dump makes no sense whatsoever. If you would like to help highlight some of this information in an oral intervention, please get in touch.
