In Canada, Thunberg participated in climate protests in the cities of Montreal, Edmonton and Vancouver including leading a climate rally as part of the 27 September Global Climate Strike in Montreal. The school strikes for climate on 20 and 27 September 2019 were attended by over four million people, according to one of the co-organisers. Hundreds of thousands took part in the protest described as the largest in the city's history. The mayor of Montreal gave her the Freedom of the City. Prime Minister Justin Trudeau was in attendance, and Thunberg spoke briefly with him. While in the United States, Thunberg participated in climate protests in New York City with Alexandria Villaseñor and Xiye Bastida, in Washington DC with Jerome Foster II, Iowa City, Los Angeles, Charlotte, Denver with Haven Coleman, and the Standing Rock Indian Reservation with Tokata Iron Eyes. In various cities, Thunberg's keynote speech began by acknowledging that she was standing on land that originally belonged to Indigenous peoples, saying: "In acknowledging the enormous injustices inflicted upon these people, we must also mention the many enslaved and indentured servants whose labour the world still profits from today."
