In Innisfil (Simcoe County), heavy duty trench covers demand is driven mainly by logistics and goods movement, light manufacturing, construction and building trades, agri-business, tourism and recreation services. The work concentrates around Innisfil Heights Strategic Employment Area (Highway 400), Alcona commercial area, Lake Simcoe waterfront / Friday Harbour. The area's anchors, including Highway 400-corridor logistics and warehouse operators, light-manufacturing tenants in Innisfil Heights, construction and trades contractors, Friday Harbour resort and marina operations, shape the kind of work Innisfil needs: load-rated, code-documented, and built for hard use.

Innisfil's 1,600-acre Innisfil Heights employment area along Highway 400 is being expanded toward Barrie for big-lot logistics and manufacturing, while Friday Harbour's marina and the booming Alcona corridor drive demand for waterfront railings, dock structures and warehouse dock equipment.
