A few hundred people gathered outside the Ontario legislature for the second Saturday in a row to protest police action during the G20 summit in Toronto.
The rally is calling for a federal public inquiry into police conduct during the summit.
During the rally, there was face painting, street theatre and music, as organizers described the day as a fun, healing event.
About 60 demonstrators started their protest with a soapy twist - a "bubble-in" inspired by a viral video of a killjoy police officer.
The video, first aired by online alternative media organization The Real News and widely available on Youtube, shows a Toronto officer threatening to arrest a young woman for blowing bubbles during G20 protests.
As the video starts, the protester is conversing with a female officer in a police line near Queen St. W. One of her male colleagues then cuts in.
"If the bubble touches me, you're going to be arrested for assault," he tells her.
When the protester puts away the bubbles and questions him about his warning, he tells her sternly:
"You want to bait the police. You get that on me or that other officer and it gets in her eyes, it's a detergent. You'll be going into custody."
The video ends with the woman handcuffed and flashing a peace sign as she is later loaded into a police van by a different officer.
Protesters gathered outside the Ontario legislature at noon Saturday and blew clouds of bubbles in a cheeky salute to the officer's notoriety.
The original version of the video had more than 90,000 views on Youtube Friday evening and had been re-posted several times.
It had also inspired a short cartoon, also posted on Youtube, titled "Officer Bubbles." The cartoon shows a muscle-bound officer resembling the one in bubble fracas arresting a young woman for dancing in the street.
"I'm touched by your expression of love," he tells her. "You are under arrest for assault."
The video finishes with a title card reading: "Next week…Officer Bubbles shoots kitten stuck in tree."
More than 1,000 people were arrested over several days last month when world leaders descended on the city.
On Wednesday, police released a 10 "most-wanted" list of G20 protesters still at large. Since then, they've made two new arrests and have issued warrants for three more people from the list.
