Standards and Legal Framework

Worksite hazardous materials are regulated by a combination of municipal bylaws, building and fire regulations and provincial occupational health and safety law. In Oakville the Town enforces local bylaws and coordinates with Fire Services and provincial authorities for workplace safety and environmental incidents.

  • Prepare and keep records: material inventories, safety data sheets (SDS), handling and disposal records.
