However, another popular sandwich chain is on the rise, and it’s ready to take over the market with its latest expansion plan, potentially threatening Subway’s long-lived reign in the sector. Â

Firehouse Subs seals deal to open multiple restaurants in Mexico
Firehouse Subs announced it has signed a multi-year development agreement with the Mexican restaurant operator Foodplay to open 100 restaurants in Mexico over the next five years, accelerating its expansion in the country.
Foodplay has also helped Yum! Brand’s (YUM)  KFC and Firehouse Subs’ sister brand, Tim Hortons, to expand across Mexico. Â
Although not all locations have been revealed, it was disclosed that units will open in Mexico City and other major cities, with the first Firehouse Subs restaurant out of the 100 set to open in Monterrey, Nuevo León.
This agreement will allow the brand to grow by expanding its presence across national, Latin American, and other international markets. It will also create hundreds of jobs and boost the country’s economy.Â
“We believe Firehouse Subs has tremendous potential in Mexico’s growing sandwich market,” said Restaurant Brands International LAC President Duncan Montero in a press release. “We’re excited to bring Firehouse premium subs, heartfelt service, and community-centered mission to new guests throughout the country,” he added.
However, Mexico is not the only foreign country on Firehouse Subs’ radar, since it also plans to open restaurants in Brazil and Australia for the first time later this year.
