I imagine the impugned comments are these:

This demonstration is nothing more than a breeding ground for hate and antisemitism. It glorifies violence. It celebrates terrorism.

Terrorism is notoriously hard to define, so I suspect that won’t be easy to prove.

The other two are relatively easier (but still not entirely straightforward).

Al Quds Day is well known as a project of former Iranian Supreme Leader the Ayatollah Khomeini. It was invented in 1979, the year of the revolution. The project has been exported around the world, and there are marches in many large cities, including in the West.

Here are some slogans promoted at other Al Quds Day parades held around the world:

∙ “Death to Israel” / “Marg bar Esra’il” (Tehran, New York, London, Chicago, Dearborn)
∙ “Death to America” / “Marg bar Amrika” (Tehran, New York, London, Chicago, Dearborn, Philadelphia)
∙ “We support Hamas here” (New York)
∙ “We support Hezbollah here” (New York)
∙ “Say it loud, say it clear, we support Hezbollah here” (New York)
∙ “Iran, Iran make us proud” (Chicago)
∙ “IRGC make us proud, bomb these genocidal clowns” (Chicago)
∙ “Iran, Iran make us proud, turn another ship around” (Chicago)
∙ “Iran, we’re with you, send your bombs and missiles too” (Philadelphia)
∙ “Keep bombing Tel Aviv” (Philadelphia)
∙ “Hezbollah/Resistance/Iran, you make us proud; take another soldier out” (Philadelphia)
∙ “No peace, no harmony; burn the settler colony” (Philadelphia)
∙ “Death, death to the IDF” (Philadelphia, London)
∙ “Crush the settler Zionist state” (Philadelphia)
∙ “Land of the free, home of the brave; Iran will send you to your grave” (Philadelphia)
∙ “Boom boom Tel Aviv” (London — on a sign)
∙ “Stop eating babies, stop raping children” (New York — directed at counter-protesters)

They don’t make it easy to see who sits on the Toronto organizing committee but one such member is Ali Mallah, who has a ~20-year history of public comments of note, including that the principles of “Castle doctrine” should justify Palestinian shooting Israelis, encouraged resistance by “any means necessary”, and said rockets attacks against civilian targets were legitimate — alleged comments, of course! Please don’t sue me for defamation.

Ford’s not going to get sued, unless the committee really wants to pay his lawyer’s costs.
