And, whether HDenier likes it or not, Jewish citizens of Canada also have free speech and other rights, such as the right to file civil or criminal charges for adjudication in the courts.
It is my understanding that the groups that campaigned in Canada against Zündel were spearheaded by Holocaust survivors (e.g., Holocaust Remembrance Association, with one leader being Sabina Citron, a child survivor of Auschwitz). The HRA urged that Zündel be prosecuted for violations of the Canadian Criminal Code (section 177, the so-called false news section). Sabina Citron herself, in December 1983, swore an affidavit against Zündel. Her doing so led to the government prosecuting him, with Crown Attorney Peter Griffiths leading the state's case.
The trial of Zündel took place in an Ontario District Court in Toronto and went forward under Canadian law and trial procedures. The prosecution had to prove that Zündel had violated a specific law, and the defense had the ability to call witnesses, cross-examine prosecution witnesses, review evidence, and argue its case. Again, whether HDenier agrees or not, this is how legal disputes are decided - even when "the Jews" are involved.
Unfortunately for HDenier, after a trial conducted according to Canadian legal norms, on 27 February 1985 a jury - not "the Jews" - found Zündel guilty on the count of spreading false news.
This conviction was appealed in 1988, and the guilty verdict reconfirmed, and then, in 1992 the Canadian Supreme Court declared the “false news” clause to be in violation of the Canadian Charter of Freedoms. The Supreme Court specifically found that the clause endangered free speech and free debate on historical topics.
OTOH, around the time of the start of the Zündel case in Canada, in 1983, West Germany revoked Zündel’s passport on account of his activities having “damaged the reputation and image of the Federal Republic of Germany.” Not "the Jews," but the government of West Germany.
HDenier sounds off about free speech but shows exactly zero awareness of what free speech is, how a government of laws works, what the legal process is, and how claims and counter-claims are decided by courts.
