Most days, you’ll find Constanza Maas on the job site. As an environmental specialist, she spends much of her time drilling into the earth, testing air and water quality, and sampling soil to monitor contamination on Canadian construction sites. But Maass impact runs deeper than environmental compliance — she’s also reshaping what leadership looks like in the trades.
After facing harassment early in her career, Maas co-founded Women On Site, a growing community that supports women across the fieldwork industries.
“I almost left the industry altogether,” she says, “but finding other women helped me stay. Now, I want to help others stay, too.” The group meets once a month to connect and create a welcoming space for fellow women in the field.
Our goal is to retain a diverse workforce, she says. The support from these women is truly amazing.
