MKULTRA's work in collaboration with a McGill researcher, in which they put psychiatry patients into a coma against their consents and tortured them : https://en.m.wikipedia.org/wiki/Montreal_experiments

This is an interesting small documentary:

Not sure how true it all is.

It's very difficult to know. Weirdly, while the CIA released a lot of the data about général MKULTRA, no data about the Montréal operations were released. There are certainly even more facets to the program we don't know about.

If you wanted to know, the CIA decided in 1973 to burn all documents about MKULTRA, fearing Watergate would lead to the Church Committee. One cache of documents had been incorrectly stored, which later came to light giving us all we are certain of about the project.

There are sources in the description. It seems legit:

What I've read so far is horrible :(

Oh, the Duplessis Orphans are a completely separate and just as tragic catastrophe of Quebec history :(

That said, yes we do actually know about the MKULTRA Montreal Programme, because of testimonies. We just don't know what more there was, and there is certainly more.

That's crazy, I never heard about that program. The CIA did a decent cover-up after the fact.

An outstanding cover-up. They convinced McGill and the Canadian government to completely shut up and not a single document relating to their actions in Montreal leaked. We don't even know the half of it.
