- October 18, 2013: The CNSC has approved a plan submitted by Shield Source Incorporated (SSI) to clean-up and decontaminate the area where tritium was processed in the facility.
Once this work is complete SSI will submit a final report describing the end-state of the facility. The report is to include clean-up activities taken, summary of any tritium releases into the environment and radiation monitoring results for workers.
CNSC staff expect to receive an application from SSI to release the facility from our regulatory oversight, noting that SSI intends to return the building to the landlord for future industrial use. This licence application will be informed by monitoring results in SSI's final report.
The CNSC will continue its enhanced regulatory oversight of the facility until it is returned to unconditional industrial use.
- March 4, 2013: Shield Source Incorporated (SSI) announced that they will not be renewing its nuclear processing licence and plan to apply for the necessary licensing to decommission the facility. The CNSC will provide regulatory guidance to the licensee throughout this process and continue its increased oversight at SSI to ensure the public and environment are protected.
- December 27, 2012: Following a hearing in Ottawa, Ontario, the CNSC renewed Shield Source Inc.'s (SSI) operating licence for a 12 month period. Under SSI's renewed licence they are still prohibited from processing tritium gas for the purpose of producing gaseous tritium light sources. This short-term licence extension is to allow SSI to complete programs and processes before they apply for a licence renewal to resume full operations. The Commission would consider a future application during a public hearing once SSI has completed its investigation to the satisfaction of CNSC staff.
- August 24, 2012: Shield Sources Inc. submits a root cause analysis report (in English only) (Source: SSI) as requested by the CNSC in its letter of April 18, 2012 to SSI. The report is an investigation of the technical and organizational factors behind the discrepancy in tritium gas (HT) emission data that led to SSI's voluntarily suspension of its tritium operations on March 28, 2012. The CNSC staff is currently reviewing the report.

- July 17, 2009: CNSC Announces its Decision to Renew Shield Source Inc.'s Nuclear Substance Processing Facility Operating Licence for its Peterborough Facility
Situated in central-eastern Ontario about 125 km northeast of Toronto, the city of Peterborough is home to two nuclear facilities regulated by the Canadian Nuclear Safety Commission (CNSC).
Nuclear fuel facility
Peterborough Nuclear Fuel Facility is owned and operated by GE Hitachi Nuclear Energy Canada Inc. (GE Hitachi). It receives uranium dioxide pellets from GE Hitachi's Toronto facility and loads them into tubes that are sealed and assembled into fuel bundles for nuclear power reactors. For more information, see GE Hitachi Nuclear Energy Canada Inc.'s Web site.
Tritium light source processing facility
Shield Source Incorporated operates a gaseous tritium light source processing facility. The facility receives tritium gas in sealed containers from a CNSC-licensed facility and then inserts the gas into glass tubes to create luminescent exit and aircraft signs. For more information, see Shield Source Incorporated's Web site.
CNSC personnel perform periodic inspections of these licensed facilities to evaluate the licensee's operations, compliance with regulatory requirements, and performance in areas including environmental protection, radiation protection, quality assurance, emergency preparedness and security.
CNSC also reviews safety program documentation, procedures and performance data to verify compliance with site-specific licence conditions, as well as with the Nuclear Safety and Control Act and its regulations.

Several other facilities licensed by the CNSC are located in Port Hope, about 50 km south of Peterborough.
