(NewsNation) — As California battles devastating wildfires, help is coming from unexpected quarters: incarcerated firefighters, Mexican emergency crews, and Canadian aircraft are joining forces to combat the blazes threatening Southern California.

The California Department of Corrections and Rehabilitation (CDCR) has deployed 931 incarcerated firefighters and 114 support staff through its Fire Camp Program as of Sunday.

These volunteers, who earn between $5.80 and $10.24 per day plus $1 per hour during emergencies, work alongside CAL FIRE personnel in 24-hour shifts.

“The work of our incarcerated firefighters and staff is an essential part of this effort,” said CDCR Secretary Jeff Macomber. “Their commitment to protecting lives and property during these emergencies cannot be overstated.”

International aid arrived as Mexico sent 72 firefighters and emergency personnel to Los Angeles. President Claudia Sheinbaum authorized the deployment as crews arrived at LAX carrying American, Mexican, and California state flags.

“Emergencies have no borders,” said California Gov. Gavin Newsom, thanking Sheinbaum for the support.

Canadian Prime Minister Justin Trudeau also dispatched aerial firefighting aircraft to assist with the emergency response, saying Canada is “always here to help our American friends.”

The Fire Camp Program, which maintains minimum-security camps staffed by approximately 1,800 incarcerated firefighters, requires strict physical and security criteria for participation. Some participants have gone on to careers with CAL FIRE after serving their sentences.
