Your question has two components. One component is outside our jurisdiction.
If we were dealing with pure fraud involving other criminal activities, we would then need to work with our police officer colleagues, such as the Royal Canadian Mounted Police or another agency.
If we see this type of promotion and the people involved intend to take money from investors, for example, in a situation where someone has invented or found a vaccine or a drug, we can take action in order to stop the activities and prevent them from continuing. We can even obtain cease and desist orders to ensure that investors don't lose money. We have ways of taking action very quickly and preventing the fraud from continuing any longer.
