The Rock play their home games at the Paramount Fine Foods Centre in Mississauga, Ontario.

They were subsequently renamed the "Toronto Rock", and began play at Maple Leaf Gardens in the 1999 season.

On May 11, 2021, the team announced the relocation from Scotiabank Arena in Toronto to FirstOntario Centre in Hamilton, beginning with the 2021–22 NLL season in December.

The franchise was founded as an NLL expansion team in Hamilton, Ontario and began play in the 1998 season.

That game featured Kaleb Toth's dramatic game-winning goal with a second left on the clock, in the last-ever professional sporting event held at Maple Leaf Gardens.

2002 was also one of the most productive years for the Rock in terms of awards; in addition to winning the Champion's Cup, three players were honoured by the league.

[10] Shortly before the 2004 season began, head coach and GM Les Bartley announced that he was fighting colon cancer, and was stepping down.

After a 2–4 start to the season, Comeau and Keenan were fired, and the Rock hired Terry Sanderson to try to turn the team around.

In 2005, the Rock defeated the Rochester Knighthawks in the East Division Final by a score of 12–10 in front of approximately 17,200 fans at the Air Canada Centre.

[12][13] Colin Doyle was named league MVP, the second straight year that the award was won by a Rock player.

[25] At the end of the month, the team announced that the Rock had been sold to Oakville-based businessman James Dawick, with Waters saying the price was "in the seven figures.

Sanderson wasted no time in the rebuilding efforts, most notably re-acquiring Colin Doyle from Washington in exchange for Lewis Ratcliff, Tyler Codron and Joel Dalgarno.

[28] He also traded Luke Wiles to Washington and Bill McGlone to Philadelphia, and re-acquiring former Rock defender Sandy Chapman from Rochester.

In August 2011, Dawick broke ground on constructing the new $20 million-dollar, privately financed Toronto Rock Athletic Centre (TRAC) in Oakville.

[3] It was originally announced that beginning in January 2024, the Rock would need to temporarily relocate their home games to the Paramount Fine Foods Centre in Mississauga, Ontario, as following their home games in December 2023 Hamilton's FirstOntario Centre would close for renovations for approximately two years.

[40][41][42] This also forced the Bulldogs and Honey Badgers to temporarily and permanently relocate to Brantford and Brampton, respectively.
