Oshawa Little Theatre didn’t always have a stage to call its own. For decades, productions came to life in borrowed halls and makeshift spaces. That changed in the 1970s when the organization purchased a former industrial building and began transforming it into a dedicated creative hub. By 1983, the dream became reality with the opening of the current theatre.
