Scope and who must comply

Owners, operators and property managers have primary responsibility for ensuring discharges meet local limits, pre-treatment requirements and any conditions in municipal or regional permits.

Enforcement is carried out by the City of Brampton By-law and Enforcement services for municipal bylaw matters and by the Region of Peel for wastewater treatment and sewer-use standards that affect Peel-operated sewers and treatment plants. Fine amounts and specific daily penalties are not specified on the cited municipal/regional pages; see official enforcement pages for the controlling instruments and up-to-date penalty schedules.[1][2]

Failing to control commercial discharges can lead to prosecution or orders to stop operations.
