The Gastown Riot. “The Battle of Maple Tree Square” drew more than 1,000 people to Gastown as a protest against the illegality of marijuana.
But police on horseback were called in to break it up, arresting 79 and charging 38. A later judicial inquiry headed by Justice Thomas Dohm criticized the action, characterizing it as a “police riot.”

A “Gastown Festival,” exactly one week after the riot, and meant to repair the area’s image, drew 15,000 peaceful participants.
