Colourful gadfly? I think you mean "Infamous German deported from Canada and incarcerated in Germany for inciting racial hatred who had close ties with one of Kathy (The Hutt) Ford's paramours".
P.S. On a personal note, my mother forbade me to deliver the newspaper to a customer in our neighbourhood that held a fundraiser for Zundel's legal fees who was visiting. My mom wasn't Jewish but man she had a hate for Nazi's, especially Toronto/Waterloo Nazi's.
P.P.S. Her fave scene in the Blues brothers movie was "I hate Illinois Nazi's" which was actually a sly reference to "National Socialist Party of America v. Village of Skokie"
