Heading out from Gore Park on Saturday after a morning of workshops, hundreds of marchers head to the nearby Federal Building on Bay Street to deliver a message to the government: we want action on climate change, with a goal of 350 parts per million of Carbon Dioxide (CO2) in the atmosphere (currently at 390ppm).

At the Federal building, there were speeches and chanting, with an exuberant group of young people leading the vocalizations. at 3:50pm, a group photo was taken, to be included in the record of actions that spanned the globe this day.
