This guide explains which agencies enforce compliance, typical steps to obtain certificates, inspection and filing paths, and how the City of Mississauga coordinates with provincial safety authorities to protect employees and customers.

Who issues certificates and who enforces them

Electrical installations and approvals are regulated province-wide by the Electrical Safety Authority; businesses must use licensed electricians and obtain the required inspection documentation and certificates from the ESA Electrical Safety Authority consumer information[2]. Fuel-burning equipment, gas piping and appliances are regulated by the Technical Standards and Safety Authority (TSSA) for Ontario; contractors must comply with TSSA rules and documentation TSSA gas safety[3]. The City of Mississauga issues building and occupancy permits and enforces municipal bylaws; confirm permit requirements with the Building Division Mississauga building permits[1].

Confirm which certificate (inspection report, permit completion, or certificate of compliance) is required before work begins.
