March 8 marks International Women’s Day. On this day we acknowledge and celebrate women’s accomplishments across the globe. This year’s theme is #Breakthe Bias. The theme focuses on creating a more inclusive, equal, and diverse world for women.


In honor of International Women’s Day, we want to shed light on three Canadian women who are paving the way for sustainability and breaking down barriers within the construction industry.

Natasha Ferguson

Natasha is the owner of EthelFox Construct Group, a renovation, roofing, and landscaping company based in Toronto. Over the years Natasha continuously had to prove her skills and ability in a male-dominated field. In an industry where she strives to break down the barriers, she was getting turned down from jobs.

Frustrated by the lack of support as a woman in trades, Natasha launched the EthelFox Construct Group. With 70% of her employees being women, Natasha wants to use her company to break down the barriers and biases for women entering and working in construction.  In addition to her company, Ferguson is launching a nonprofit called A Women’s Work in 2022. The nonprofit is aimed to support and offer training for women in the industry.


Ferguson hopes to break down the barriers for women and help them pursue careers across the male-dominated field.



Birgit Siber
