A public interest information project about nuclear waste burial in Canada.
Know Nuclear Waste
What is nuclear waste?
Nuclear wastes are the radioactive by-products of developing and using nuclear technologies, including nuclear power reactors and nuclear weapons. Nuclear fuel waste is also called "high level" waste, and is the most radioactive of the waste products generated by nuclear power production. Read more HERE

Important Links and Documents for Review Closing Feb 4
The Impact Assessment Agency web page about the NWMO DGR project review includes key documents and notices related to the review, as well as posting of public comments. The current comment period is on the Initial project description, and there are two versions: the summary document is 92 pages long, and the full document including the Initial Project Description is 1,322 pages BUT only the first 262 pages of that document is the detailed (well, more detailed than the summary) version of the Initial Project Description. There is also a 10 page summary at the beginning of the full IPD.
The NWMO had pronounced in August that the transportation of radioactive waste would not be part of the impact assessment process. It’s a weak argument – for 20 years the NWMO has been describing transportation as part of their project, the regulators have acknowledged that, and the Impact Assessment Act requires activities that are integral or – in the language of the Act - ‘incidental’ to the project be included in the assessment. There's no nuclear waste burial project if there's no nuclear waste to bury, and there's no nuclear waste in northern Ontario unless the NWMO transports it in from reactors in other regions.
NWMO's Nuclear Waste Project Milestones
2020 - In 2020 the Nuclear Waste Management Organization focused their investigation of potential burial sites for all of Canada's high level nuclear fuel waste on two remaining areas: the Revell Lake area, 45 kilometres west of Ignace, in northwestern Ontario, and an area just north of Teeswater in the Municipality of South Bruce in southwestern Ontario. In November 2024 they announced that they had selected the Revell site in northwestern Ontario
January 2026 - A federal review of the Nuclear Waste Management Organization’s nuclear waste transportation and burial project was launched on January 5th with a 30 day comment period on the Initial Project Description closing on February 4th.
The NWMO has excluded transportation from its Initial Project Description, proposing that transportation issues not be part of the federal review.
Nuclear Waste On-line is a series of on-line presentations about nuclear waste in Canada. For the 2026 line up and past recordings click HERE.
What is the nuclear industry looking for?
The nuclear industry - under the banner of the Nuclear Waste Management Organization - is looking for a community willing to become the "host" to all of Canada's nuclear fuel waste - approximately 50,000 tonnes to date. The NWMO plan is to place the waste deep underground. It includes the option of centralizing the waste in temporary storage at the site selected for a geological repository while research is still underway and prior to the site having been fully investigated.
2024 - On November 28th 2024 the Nuclear Waste Management Organization announced that it had selected the Revell site in northwestern Ontario as the location for their proposed deep geological repository for all of Canada's high-level nuclear waste. Read more HERE

IMPACT ASSESSMENT LAUNCHED OF NUCLEAR WASTE PROJECT - COMMENT BY FEBRUARY 4
Welcome to our information web site about nuclear waste.
This site has been created to provide ordinary people with information about an extra-ordinary challenge: the long term management of the highly radioactive waste that is created as a byproduct of using nuclear power to generate electricity.
In Canada - as in several other countries that use nuclear power - the nuclear industry is committed to the idea of burying the nuclear fuel waste deep underground in a rock formation. In 2002 the federal government gave the nuclear industry permission to organize themselves as the Nuclear Waste Management Organization and so relaunch their search for a suitable site and a willing community, and in May 2010 the Nuclear Waste Management Organization formally launched their search for just such a community.
As of August 2012 twenty-two communities were allowing themselves to be studied as possible end points for all of Canada's high level nuclear waste: three in northern Saskatchewan, thirteen in northern Ontario, and six in southwestern Ontario.
In November 2013 the NWMO dropped two from northern Saskatchewan and two from northern Ontario. In January 2014, two communities in Bruce County were dropped, and in June 2014 the town of Nipigon withdrew. The NWMO dropped Brockton in December 2014, and Spanish and the Township of the North Shore in January 2015. In February 2015, Creighton, Saskatchewan and Schreiber, Ontario were removed from the NWMO investigations. The Municipality of Central Huron and the Township of White River were dropped by the NWMO in June 2017, and in December NWMO announced that the area around Blind River and Elliot Lake, Ontario, will no longer be considered. In November 2019 the Townships of Hornepayne and Manitouwadge were taken off NWMO’s list, and in January 2020 NWMO announced that it had signed agreements with landowners in South Bruce , and would no longer consider Huron Kinloss as a potential host.
On November 28 2025 the NWMO announced that it had selected the Revell site between Ignace and Dryden in the heart of Treaty 3 territory in northwestern Ontario.
