I started watching a Canadian TV series which Netflix bought called "Intelligence" which you guys might find very interesting. It's about the intelligence wing of the Vancouver Organized Crime Unit (OCU), their relationship with CSIS (Canadian CIA) and their informants In organized crime. It seems like they are doing investigations that would be FBI jurisdiction in the USA (I thought RCMP investigated organized crime in Canada but according to this show, it is the jurisdiction of OCU, which may or may not be something that is due to Vancouver being such a huge port). Anyway, one of the ideas floated on the show is that the United States Drug Enforcement Agency (DEA) is doing covert operations in the Vancouver port regarding drugs being shipped into or out of Canada, which the Canadian LE knows nothing about. The OCU eventually learn that the DEA is doing surveillance on one of their informants and fucking up one of their operations. The DEA guy on the show is undercover, but they figure out what he is up to through informants and arrange a meeting with him. They don't seem to ever question his ability to surreptitiously perform surveillance on a Canadian citizen inside Canada- they just say "knock it off dude, he is our informant and you are fucking up our investigation, so cut the fucking shit." And he is cool with it, and cuts the shit. Later on, the Canadian OCU characters are like, "WTF?????? Are we the 51st State??"
One of my best friends is an FBI Special Agent in New York City and I knew he had some prior interactions with Canadian LE and I mentioned this show to him and what is being portrayed. He told me they always "try" and contact their Canadian counterparts and give a heads up if they have to interview witnesses. Of course, where a covert operation is going on, I do not know what rules actually apply and whether a "heads up" can or should be given. But there is at least an implication that the DEA is operating covertly in Canada without telling anyone of authority in Canada. Whether that is real or not I do not know.
Later on in the series the OCU does involve the DEA guy in their own investigations and attempt to work out a scheme by which one of the subjects of investigation is to be lured into the USA and then arrested.
It is a good show and I can see why Netflix invested some money in this TV series. It has some similarities to the US TV show The Wire and it seems to have been produced in the same time frame. Not as dark as The Wire but many similar attributes.
