Crews from Saint John Fire remain at the Saint John Transit building on the east side after workers could smell natural gas.
The building has been evacuated as a precaution.
District Chief Joe Armstrong tells CHSJ News the smell was strong in the main boiler room and the gas has since been shut off to the building.
Crews using detection equipment have not been able to get any strong readings in the building and the smell is dissipating.
Enbridge Gas is en route to the area and Armstrong tell us they are in a holding pattern until they arrive.
