Protesters showing solidarity with people arrested during the G20 summit in Toronto interrupted Canada Day celebrations in Winnipeg's Osborne Village on Thursday.

More than 100 protesters marched through a neighbourhood street festival at about noon and formed a circle, chanting "our passion for freedom is stronger than their prisons."

Activist Jodi Proctor said the march was in support of hundreds of people arrested during the summit last weekend.

"We're saying 'Thank you for speaking out on our behalf, for these issues that are important to many of us,'" Proctor said. "'And we absolutely denounce the fact you are being criminalized for it.'"

David Jacks of the Canadian Federation of Students said he was in Toronto for what was supposed to be a peaceful protest.

Federation members felt helpless watching police treatment of "our brothers and sisters," Jacks said. "My hand's shaking just thinking about it."

Jacks said 14 of those arrested in Toronto were from the student group.

The Winnipeg demonstration was one of several being held across the country Wednesday and Thursday.

Proctor said she supports calls for a public inquiry into the G20 arrests, which the Canadian Civil Liberties Association has described as unprecedented, disproportionate, arbitrary and excessive.
