In the summer of 1996, 30 years after the original UBC baseball program was disbanded due to budget cuts, Athletic Director Bob Phillip along with former professional Jim Murphy and community baseball coach Mark Hiscott provided funding for the present day Thunderbirds baseball. Hiscott recognized student Terry McKaig, a former collegiate player and national team member, as the one to take over the program as head coach. Since 1997, McKaig has been the driving force behind the T-Birds with support and funding from such major leaguers as Jeff Zimmerman and Ryan Dempster. In 2015, Chris Pritchett was named the new head coach of the baseball team and Terry moved up to the position of Director of Baseball.

The Thunderbirds compete in the United States as the only Canadian member of the National Association of Intercollegiate Athletics (NAIA). In 2001, the program reached a new level as the New York Mets made Derran Watts the first ever Thunderbird to be drafted, when they selected him in the 12th round. Since then nine more Thunderbirds have been drafted including 2007 World Series starter Jeff Francis. T-bird baseball successes include their trip to the 2006 and 2025 NAIA World Series

The UBC Thunderbirds football team has won the CWUAA Hardy Trophy conference championship 16 times, which is third all-time among competing teams. On a national level, the team has won the Vanier Cup championship four times, in 1982, 1986, 1997 and, most recently, in 2015. The team has also lost three times in the title game, in 1978, 1987, and 2023. The Thunderbirds program has also yielded three Hec Crighton Trophy winners: Jordan Gagner in 1987; Mark Nohra in 1997; and, most recently, Billy Greene in 2011.

Father David Bauer coached the Thunderbirds for two seasons, and led the team to a Western Canadian Intercollegiate Athletic Association championship in 1963, and reached the final game of the Canadian Interuniversity Athletic Union men's ice hockey championship tournament for the CIAU University Cup, but lost by a 3–2 score to the McMaster Marauders.

Bob Hindmarch began coaching the men's ice hockey team during the 1964–65 season, and led them to the 1971 Western Canadian Intercollegiate Athletic Association championship. He accumulated a winning record in 11 of 12 seasons, and set UBC record with 214 wins by a coach in ice hockey. In December 1973, they became one of the first Western Bloc sports teams to tour China, and played a series of games focused on friendship and teaching hockey skills to local players. The trip was supported by the Government of Canada as part of a desire to normalize relations with China, and was not well-publicized at the time. The Thunderbirds won all seven games played by a combined scored of 56 to 5.
