I'm really happy that you raised the issue of the source, because we do need to identify the source of any contamination, and that is the reason that I will be reaching out to my provincial counterpart as soon as possible. I spoke with my deputy minister and asked him to draft that letter and to arrange that communication, so that is in process right now.
I also spoke with Minister Guilbeault, who indicated to me that on the other sites that were contaminated, there was a nine-month period during which the Alberta regulator did not notify the communities. That's an issue I will bring up with my provincial counterpart as well. There are many possible sources. We need to determine the source, and it will be with multiple levels of government and departments, but I will stay on top of it.
