According to organizers, an estimated 500, 000 people marched in the streets of Montreal, marking it the largest strike in the city's history, said Mayor Valerie Plante.

With homemade signs in hand, a group of Montreal seniors marched behind an orange banner reading: “A liveable planet for our grandchildren.”

The Montreal rally drew hundreds of thousands of protesters in the fight against climate change.

Justin Trudeau and Elizabeth May will take part in Montreal's climate change march on Friday, while NDP Leader Jagmeet Singh will join a similar event in B.C.

Dawson College is showed solidarity for the movement by finding ways to lessen its carbon emissions and impact on the planet.

Some Montreal school boards cancel classes on Sept. 27, allowing students to attend the climate march.

The rally attracted concerned citizens and Indigenous leaders from British Columbia and Quebec who are opposed to the Trans Mountain expansion pipeline.
