Posted on May 23, this powerful black and white film shows protesters of all ages, races and hues taking to the streets to protest Canada’s emergency law Bill 78, a draconian attempt to quell massive student protests over tuition hikes that have taken over Quebec for more than 100 days.

The nightly “casseroles” march began with a Facebook callout on May 19 from a politics professor outside Montreal, the Guardian reported. People were told to meet on the street at 8 pm with pots and pans and make as much noise as they could. The pots-and-pans protest has its roots in Chile, where people have used it for years as an effective, peaceful tool to express popular defiance.

It appears to be taking off as a new symbol of resistance and solidarity and it’s reinvigorated the Montreal student movement.
