Video shows protest against Trump in New York?

A video showing a large crowd with flags is misrepresented as a protest against Donald Trump in New York. In reality, it depicts an Iranian diaspora demonstration in Toronto, Canada, advocating for the recognition of Reza Pahlavi as a democratic leader. The event, reported by CBC, attracted around 350,000 participants, not the claimed seven million. The video is confirmed to be false regarding its location and context.
