The Canadian Nuclear Safety Commission (CNSC) is Canada’s nuclear regulator. The CNSC conducts their own environmental sampling through their initiative called the Independent Environmental Monitoring Program (IEMP). This program verifies that the public and the environment around licensed nuclear facilities are safe.
The IEMP involves taking samples from public areas around facilities and measuring and analyzing the amount of radiological and hazardous substances in those samples. CNSC staff then collect the samples and send them to their laboratory for testing and analysis.
The CNSC recently released results from their 2025 IEMP, which details sampling from areas around BWXT’s Toronto facility at 1025 Lansdowne Avenue.
The CNSC’s IEMP is conducted in addition to BWXT’s environmental program which demonstrates that the public and the environment are protected from emissions related to our facility’s activities.
As noted by the CNSC, “IEMP results from 2014, 2016, 2018, 2019, 2022 and 2025 are consistent with the results submitted by BWXT NEC, supporting our assessment that the licensee’s environmental protection program is effective. The results add to the body of evidence that people and the environment in the vicinity of BWXT NEC – Toronto are protected and that there are no anticipated health impacts from the operation of the facilities on the site.”
The 2025 results are available on the CNSC’s website here: Independent Environmental Monitoring Program: BWXT Nuclear Energy Canada Inc. – Toronto.
