Who we are

The Thunder Bay Roller Derby League is an exciting and fast-growing group of die-hard roller derby enthusiasts, comprised of skaters, referees, Non-Skating Officials (NSOs), volunteers. Our two home teams (the Grizzly Madams and the Elle Capones) generate an exciting buzz with the at-home bouts during the summer, while our travel team, The Babes of Thunder, compete at home and throughout Canada and the United States.

Where we practice

All the sweat, blood, and tears happen in our secret practice space. This is where our veterans, referees, and freshmeat train year round to bring our fans a nail-biting roller derby experience during our summer season. Insured skaters visiting from other leagues are welcome to join our practice for a $5 drop in fee, which we wave if you share a technique or drill.

Where we play

When it comes to bout season, our rough and tough skaters hit the tracks at Thunder Bay venues such as the Delaney arena, Fort William Gardens, and the Neebing arena. These venues have ample seating, as well as snacks, beverages and a beer garden for your derby-viewing pleasure. (Don’t forget to bring your fave-skater-signs!)

Our Season

The Thunder Bay Roller Derby League’s home bouting season runs from May – July, where you can catch the Grizzly Madams take on the Elle Capones in teeth-gritting action. The Babes of Thunder compete and play throughout the winter, spring, and summer seasons. Never a dull moment if you’re a derby lover! (And who isn’t, really?)
