Toronto Roller Derby is stirring up some four-wheeled pandemonium with its Quad City Chaos tournament weekend. All day Saturday and Sunday, girls from Montreal, Ohio, Indiana, and Toronto will be tearing up the flat track. The headlining bouts take place Saturday night between Ohio Roller Girls A-Team and Bleeding Heartland Flatliners, followed by Montreal New Skids on the Block versus Toronto’s CN Power.
