At least 28 mass graves containing the remains of indigenous children who died in the 'care' of religious and government institutions have been discovered in Canada, prompting calls for an independent inquiry from First Nation leaders across the country. One of the sites is the notorious Allan Memorial Institute at McGill University, where Donald E Cameron conducted research as part of the MKULTRA program including LSD experiments and 'electroconvulsive therapy at 30 to 40 times the normal power' (Wikipedia).

Montreal: Allan Memorial Institute, McGill University, still in operation since opening in 1940. MKULTRA experimental centre. Mass grave of children killed there north of building, on southern slopes of Mount Royal behind stone wall.

Although some of the horrors of this program are already well-known, these revelations indicate that there is much, much more that remains classified: this information has come to light only through archaeological investigation, and it will be interesting to see whether the First Nations are successful in their quest for an independent inquiry into North America's genocidal (recent) past.
