The Oshawa market for demolition

Demand spans industrial site work, institutional development, and servicing.

Activity clusters in the automotive assembly lands, downtown Oshawa, the university and college district, and the north-end industrial parks. Harrowgate Group regularly builds demolition for Oshawa clients like automotive manufacturers, the university, institutions, and the City of Oshawa, each project carrying its own site and requirements.

Oshawa conditions shape the response: legacy automotive-site redevelopment, institutional-campus growth, and mixed older industrial stock.
