Thousands of Montrealers took part in Sunday’s People's Climate March.

The route took participants from the starting point at Lafontaine Park to Jeanne-Mance Park.

The march was one of hundreds that took place Sunday around the world, including a mass march in New York City that attracted upwards of 100,000 people.

There were scores of events planned in communities across Canada.

In Quebec, marches also took place in Baie-Comeau, Gaspé, Rimouski, Quebec City, Trois-Rivières, Drummondville and Saint-Jean-sur-Richelieu.

The marches were planned to coincide with the UN Climate Summit at the organization’s New York headquarters on September 23.

Heads of state will gather there in preparation for the decisive Conference on Climate Change in Paris in December 2015.

Canada's Prime Minister Stephen Harper is facing criticism for the fact he will not be attending the UN Summit, despite the fact that he'll be at the UN later in the week to address the General Assembly for the first time since 2010.

Environment Minister Leona Aglukkaq will represent Canada at the Climate Summit.
