Saint John Tool Library (Image from Facebook) The Saint John Tool Library wants to help fill the need for construction workers in the region. The library launched a job readiness program Monday at its new training centre on Princess Street. Brent Harris, the founder of the tool library, said the program will be aimed at people facing barriers to employment. “We’ll be offering four training modules: working with concrete, roofing, general carpentry, and drywall and crack-filling,” Harris said. Harris said Saint John is reinventing itself and it is being fueled by a construction boom, particularly in the uptown core.
