A crematory expert from Calgary, Alberta, who had been responsible for the disposing of 10,000 bodies in his career, Lagace finally sorted out - publicly and in open court - all the fanciful lies about the Germans supposedly "cremating multiple corpses in single corpse retorts" in Auschwitz, Birkenau and elsewhere. Lagace's testimony put an end to the wild claims by so-called "death camp survivors" about ". . . cremating bodies in five minutes" etc. His testimony - together with Fred Leuchter's findings as well as the lab results presented by Dr. James Roth of Alpha Laboratories from the soil and rock samples Leuchter had brought from Auschwitz to the USA - spelled the death knell of fanciful "survivor" claims. Lagace was raided by the Royal Canadian Mounted Police in his crematory office where he was making notes and keeping photographs taken for future court cases hidden in a container for human ashes. Zündel witness in the Great Holocaust Trial of 1988.
Became the target of several Royal Canadian Mounted Police raids. Resigned from his job as crematory director after receiving endless threats by anonymous callers and from thugs claiming to be the Jewish Defense League.
