Activity clusters in the automotive assembly lands, downtown Oshawa, the university and college district, and the north-end industrial parks. Clients such as automotive manufacturers, the university, institutions, and the City of Oshawa drive much of the Oshawa work, and no two projects carry the same scope or ground.
