CALGARY, Alta. — Protestors are planning to block roads and shut down the City of Calgary during the upcoming G-8 Summit, according to the Calgary Herald.

The newspaper is reporting it has inside information regarding a planned Showdown at the Hoedown — a mass protest at a city-sponsored gala party for delegates and journalists.

The Anti-Capitalist Collective is apparently behind the protests, but the group has refused to comment. Mayor Dave Bronconnier, says there will be heavy security on-hand to prevent disruptions.

“Calgarians are not going to be intimidated by a group of people who think they are going to … blockade roads and not allow people to get to work,” Bronconnier tells local media. “Those who wish to disrupt the city do so at their own peril.”

Major protests are planned for Calgary during the G-8 Summit, which takes place next week in Kananaskis. A Web site has been rallying support for a “march to blockade downtown Calgary” on June 26. It says “Moving blockades (otherwise known as snake marches) will be used to disrupt business in the downtown core.”
