The defining experimental style of Theatre Gargantua's productions are a hybrid of Thomas' studies in Europe, which include creation as an artistic collective, an extended development phase, imagistic production elements, original composition often performed live and choreographed physicality of performers.
[1] The topics of exploration in Gargantua's past shows have been grounded in social issues, creating compelling work that is presented through highly physical performances.
The Theatre Gargantua style of performance is as much physical as textual, with productions being built by the company from the ground up over a period of years.
Theatre Gargantua’s SideStream project is developed by core and associate artists,[10] designed with touring in mind.
In the summer of 2023, Gargantua led a new initiative in partnership with the Bank Art House in Welland, Ontario, through which they featured work-in-development by artists including: Teiya Kasahara, Beryl Bain, and Heather Marie Annis.
