Background on the Deep Geologic Repository
Since the 1970s Ontario Power Generation has maintained a record of safely storing waste from the Pickering, Darlington and Bruce nuclear stations.
In 2001, the Municipality of Kincardine approached OPG to jointly develop a long-term disposal facility for low and intermediate level waste at the Bruce nuclear site.
The result was the Deep Geologic Repository (DGR), an initiative with community support, regulatory backing, and a solution supporting Ontario’s long-term energy needs.
An Independent Assessment Study identified three options that were technically feasible and capable of safely storing the waste:
- A deep geologic repository (DGR)
- An enhanced processing, treatment and long-term storage
- A covered, above ground concrete vault
In 2004, the Municipality of Kincardine - by resolution - endorsed moving forward with the DGR because of its higher safety margins.

Memorandum of Understanding
Following the Municipality of Kincardine’s resolution, OPG and the Municipality of Kincardine signed a Memorandum of Understanding (MOU) in April 2002, which set out the terms to develop a plan for the long-term management of low and intermediate level waste at the Western Waste Management Facility (WWMF) located on the Bruce site.
Kincardine endorses DGR
After the Independent Assessment Study Report, Kincardine Council passed a resolution on April 21, 2004 (Kincardine Council #2004-232) to:
"...endorse the opinion of the Nuclear Waste Steering Committee and select the "Deep Rock Vault" option as the preferred course of study in regards to the management of low and intermediate level radioactive waste"
This was because the DGR had the highest margin of safety and is consistent with best international practice.
Surrounding municipalities that also expressed support for the DGR proposal include:
- Saugeen Shores
The Kincardine Council indicated they preferred the Deep Geologic Repository because:
- It provides the highest level of safety of any option.
- There will be a rigorous environmental assessment and Canadian Nuclear Safety Commission regulatory process.
- The DGR will permanently isolate the low and intermediate level waste stream, much of which is already stored on site.
- No high level waste or used nuclear fuel would be allowed.
2004 Hosting Agreement
Hosting agreements are commonly used in jurisdictions across Canada and internationally for communities that support the location of a long-term waste management facility.
The Hosting Agreement was signed on October 13, 2004. It includes the following provisions:
- OPG will design, license, construct and operate a deep geologic repository for low and intermediate level waste streams currently stored at the WWMF.
- Kincardine, Saugeen Shores, Huron-Kinloss, Arran-Elderslie and Brockton will be paid over 30 years subject to achieving key milestones.
- No used fuel would be stored in the DGR.
- Kincardine Council obtains endorsement from Kincardine residents.
2018 Amendment to Hosting Agreement
Community input: taking the poll
Kincardine Council sought endorsement for the hosting agreement from Kincardine residents through a community poll.
A community education plan put in place provided all residents an opportunity to obtain information about the DGR concept and the hosting agreement.
Telephone polls by an independent party took place in January and February 2005, and efforts were made to contact each household and each eligible resident by either telephone or mail. Seasonal residents were mailed a copy of the question and asked to respond by mail.
Of the 5,257 households deemed eligible to contribute to the poll (according to 2001 Statistics Canada Census), 3,763 participated. This represented 6,778 individual votes, and Kincardine Council accepted the results as indicating sufficient support to move forward with the Hosting Agreement for the DGR.
