Property compliance in Ontario
Ontario layers provincial codes over municipal by-laws more heavily than most provinces. The Ontario Building Code and Ontario Fire Code set the baseline, the ESA regulates every electrical installation, the TSSA covers elevators, boilers and fuel systems, and the AODA adds accessibility deadlines that apply to most organizations. On top of that, cities like Toronto, Hamilton and Waterloo run their own rental licensing and apartment standards programs.
The regulatory landscape
| Building code | Ontario Building Code (O. Reg. 332/12) |
|---|---|
| Fire code | Ontario Fire Code (O. Reg. 213/07) |
| Electrical | Electrical Safety Authority (ESA) — Ontario Electrical Safety Code |
| Technical safety (boilers, elevators, fuel) | Technical Standards and Safety Authority (TSSA) |
| Accessibility | Accessibility for Ontarians with Disabilities Act (AODA) |
| Rental housing | Residential Tenancies Act and local property standards by-laws |
