I didn't know that William Lyon MacKenzie King was involved with this. He is famous in Canada for having had a great belief in seances, wherein he would consult his late mother for advice about running the country. I seem to recall that he was a fanatic about his little dogs too.

His mom's ghost apparently didn't have much military knowledge, as she failed to warn him about Dieppe.

It is ironic that he would have had a connection with helping Rockefeller put down workers' unions. His ancestor was William Lyon MacKenzie, a journalist (and eventually the leader of an armed rebellion) who had his printing press chucked into Lake Ontario for writing tirades against the Powers That Be.
