Portable Toilet Usage Chart for Construction Sites in Hamilton

Portable toilet usage chart on construction sites in Ontario is regulated by the Ministry of Labour of Ontario under the Construction Health & Safety Act and its Regulation 213-91, Section 29 as amended by Regulation 145/00. Under this regulation, the Ministry calls for heated portable toilets with flushing systems and warm water (where possible).

This regulation also states that a heated unit must be used whenever possible.
