[9] The franchise has started to return to prominence after qualifying for the post-season in eight of the 10 years of the 2010s, including appearances in the 101st, 102nd, 107th and 108th Grey Cups, where they lost each time.

On January 2, 2022, the club reorganized its ownership under the newly announced Hamilton Sports Group, an entity that also owns Forge FC and the master licence for Tim Hortons Field.

Bob Young continues to serve as chairman and the largest shareholder while also welcoming new investment from Hamilton-based steel company Stelco (represented by its chairman and CEO Alan Kestenbaum), club CEO Scott Mitchell, and local sports executive Jim Lawson.

[12] In late 2024, American steelmaker Cleveland-Cliffs acquired Stelco, including their 40% share of Hamilton Sports Group.

In the following season (1913), the Tigers won their first of five Grey Cups when they beat the Toronto Parkdale Canoe Club by the lopsided margin of 44–2.

It is believed by some that the failure of the Tigers is what caused the IRFU to be dissolved, and the Eastern Rugby Football Union (ERFU) to be formed.

In 1943, the Hamilton Flying Wildcats, stocked with Royal Canadian Air Force personnel, won the 31st Grey Cup.

At this time, the Tigers and Wildcats competed for fans, talent and bragging rights so vehemently that neither team could operate on a sound financial level.

Players, such as Angelo Mosca, Bernie Faloney, Joe Zuger and Garney Henley became football icons in the Steel City.

Beginning in 1957 under coach Jim Trimble (who left the team after the 1962 season), the Tiger-Cats played in every national final through 1967, except for those of 1960 and 1966, winning 4 Cups (1957, 1963, 1965 and 1967).

The Cats' 1972 Grey Cup win, 13–10 over the Saskatchewan Roughriders, was led by two sensational rookies, Chuck Ealey who had an outstanding college career at the University of Toledo and Ian Sunter, an 18-year-old kicker who booted the deciding field goal that gave Hamilton the cup on their home turf.

[23] The Tiger-Cats contended on and off during the rest of the 1970s and 1980s (reaching the playoffs in every year of the latter decade), reaching the Grey Cup game again in 1980 and winning the East Division by a mile in 1981 with an 11–4–1 record under head coach Frank Kush, but were stunned by the Ottawa Rough Riders, who finished a distant second at 5–11, in the East final.

The Tabbies' defence was very stout, talented and hungry that decade, led by standouts Grover Covington, Ben Zambiasi, Howard Fields and Mitchell Price.

They were complemented very well on offence with quarterbacks Tom Clements and Mike Kerrigan throwing to Rocky DiPietro and Tony Champion leading to three straight trips to the Grey Cup in 1984, 1985 and 1986, the latter resulting in winning the title over the Edmonton Eskimos by a score of 39–15.

[23] After the Tiger-Cats beat the Toronto Argonauts in the 1986 Eastern Final, Ballard said "You guys may still be overpaid, but after today, no one can call you losers.

Quarterback was a weak spot for the Ti-Cats, as the first half of the decade had names like Don McPherson, Damon Allen, Timm Rosenbach, Matt Dunigan, Lee Saltz and Todd Dillon taking their turns at the pivot.

Despite the excellent play of Eastern All-Star Earl Winfield rewriting the team's record books for pass catching, Hamilton struggled to attract crowds to Ivor Wynne Stadium.

It was not until 1998 with the arrival of head coach Ron Lancaster and the pitch-and-catch duo of Danny McManus and Darren Flutie plus the pass rush abilities of Joe Montford that led Hamilton back to the CFL's elite, reaching the Grey Cup finals in 1998 and winning the cup the following year.

[27] Native Hamiltonian Bob Young has owned the Tiger-Cats since 2004, and although the team had a resurgence in home attendance, corporate sponsorship plus a brand new "Tiger Vision" scoreboard at Ivor Wynne stadium, it struggled with its on-field performance.

On November 24, 2013, the Hamilton Tiger-Cats lost to the Saskatchewan Roughriders 45–23 in the 101st Grey Cup at Mosaic Stadium at Taylor Field.

The game had star appeal as actor Tom Hanks attended with comedian Martin Short, a Hamilton native.

Early in the third quarter, Hanks was shown replacing a Ti-cats toque with a Riders hat, drawing a loud roar from the crowd.

The artwork for the original "leaping tiger" was designed by Jake Gaudaur,[30] a former Tiger-Cat player, President, and CFL Commissioner.

The first meeting took place on October 18, 1873 at the University of Toronto where the Argonauts defeated the Hamilton Football Club by a Goal and a Try to Nil.

Other Tiger-Cats rivals include the Montreal Alouettes, the Ottawa Redblacks, and recently the Winnipeg Blue Bombers after a pair of Grey Cup matchups.

[31][32] Hamilton Tiger-Cats games broadcast on CHML were anchored by the announcers team of Rick Zamperin, John Salavantis, and Matt Holmes.

(CHML continued to carry The Fifth Quarter as an unofficial postgame show, with Rick Zamperin as host, until the station's closure.)

[33] Through the 2015 season, former McMaster Marauders quarterback Marshall Ferguson offered sideline analysis of all Tiger-Cats games, along with a post-game show on TSN 1150 Hamilton.
