FirstOntario Centre (originally Copps Coliseum) is a sports and entertainment arena at the corner of Bay Street North and York Boulevard in Hamilton, Ontario, Canada.

The 1986 World Junior Ice Hockey Championships were held in Southern Ontario, with Copps Coliseum used as the primary venue.

Copps was the primary host for the 1987 Canada Cup, and the site of the famous Gretzky to Lemieux goal that beat the Soviets 6–5 in the final.

The arena hosted the 1990 Memorial Cup and set the single game attendance record, on May 13, 1990, with 17,383 spectators watching the Oshawa Generals defeat the Kitchener Rangers, in the final, 4–3 in double overtime on a Bill Armstrong goal.

Copps hosted the WWF pay-per-view Breakdown: In Your House on September 27, 1998, and the Billy Graham crusade that year, attended by 19,000 spectators each night.

On January 27, 2014, Hamilton City council voted unanimously to approve a $3.5-million deal to rename Copps Coliseum after local credit union First Ontario.

The renovations were delayed until December 2023 which allowed the Rock to play their first couple games of the 2023–24 season at the arena, before moving to the Paramount Fine Foods Centre in Mississauga, Ontario.

On June 7, 2007, the AHL Hamilton Bulldogs won their first Calder Cup Championship in franchise history at home in Copps Coliseum, defeating the Hershey Bears.

Copps Coliseum was built to National Hockey League capacity and specifications in the hope that it would allow Hamilton to acquire an NHL expansion franchise.

In 2007, Waterloo billionaire Jim Balsillie, co-CEO of Research in Motion, made an offer to purchase the Nashville Predators for $220 million US.

In the spring of 2009, the Phoenix Coyotes filed for bankruptcy and Jim Balsillie immediately offered a rumoured $212.5 million US, while stating he wanted to move the franchise to southwestern Ontario.

In 2007, from March 3 to 11, Copps Coliseum hosted the 2007 Tim Hortons Brier, the annual Canadian men's curling championship.
