A citizens' committee filed a lawsuit. TCE is carcinogenic, so the citizens' group sued the federal government, seeking recognition of the causal link between drinking water contaminated with TCE and cancer cases in Shannon, but the Shannon sample was too small to prove it.
Did national defence admit to being at fault, in the sense that it admitted it had contaminated the water? My understanding is that, yes, it did. I don't think the contamination was deliberate. In the 1950s, when they were using these solvents, they didn't know how harmful they could be. The fact has been acknowledged.
However, should national defence, in good conscience, have notified people sooner that contamination had occurred? We know that, by the time it was detected, the department had known about it for several years. I don't want to get into those details, because I don't know why nobody said anything. I don't know if it was knowledge or communication that was lacking. I have no idea.
However, I know that the courts recognized the federal government's responsibility and held the federal government to account for the contamination. Then, from 2023 to 2025, financial compensation was awarded to people who lived there, particularly in places where there were plumes of contaminants. The compensation was awarded primarily for the inconvenience caused by the contamination.
However, the federal government has not acknowledged a link between disease or cancer cases and contamination. In addition, the link could not be scientifically demonstrated because the sample size was too small.
Does that answer your question?
