    Bomb Girls

    GECO was a shell filling factory – empty shells were sent to GECO, and its workers would have the dangerous task of turning them into explosives, and shipping them overseas.  The workforce comprised mainly young women with no factory experience, and at times, no work experience at all. Dubbed “Munitionettes,” “Fusiliers,” or “Bomb Girls”, they had a half day’s training and took a secrecy oath before being put to work. 

    An estimated 21,000 people worked at the factory during its four years of operation, creating a unique community. The company had its own newspaper, called the GECO Fusilier, and for $1 a year workers could join the GECOcites Recreation Club which hosted softball games and built a mini-putt green and a lawn bowling area. There were sold out monthly dances, Victory bond drives and gardens, talent shows, and bingo was so popular that they had to stagger seatings. Workers took breaks in a massive 2000 seat cafeteria where the kitchen served 3000 meals a day, and an annual Christmas dinner of 400 turkeys. With the help of a Canadian Government incentive, the factory even provided childcare for working mothers.

    Working at the factory

    Eglinton Avenue did not yet cross the Don Valley, and was not the major corridor between east and west that it is today. Most of the workforce came from the downtown core, so GECO set up its own bus line with seven downtown stops. In a typical twelve month period, the 26 buses per shift carried an equivalent of ¼ of Canada’s population, 24 times around the world.

    The plant ran 24 hours a day, six days a week,  and for four years, had not a single fatal accident. Once they arrived, workers had to go through change houses to get from the “dirty” side of the plant to the clean side of the plant where the munitions were filled. The clean side had no windows, and each building was interconnected. Uniforms were washed every shift, and the work rooms cleaned daily in hopes of keeping out dust, static, or anything that could cause a spark. Workers had to wash, take off their clothes down to their undergarments, and remove anything metal (including bobby pins, or bra clasps). They changed into uniforms and were inspected by the matron in charge before being allowed to enter to the clean side. A process they would have to repeat for their lunch break.

    Remembering GECO

    For nine years after the closure of the munitions factory, some of the buildings were used for emergency housing for an estimated 6000 people in need and returning soldiers. Today, 17 of the original buildings still stand, and parts of the elaborate tunnel system survive.

    Historian Barbara Dickinson has researched the GECO factory and its workers in great detail in her book, “Bomb Girls” (2015). Her extensive research has even informed a CBC television series, and in 2017, a documentary was released with first-hand accounts from women who worked in the former factory. The same year, a mural was unveiled to honour the Bomb Girls as part of the Underpass Project at Warden and St. Clair Avenue.
