Building safety in Mississauga

Building owners, the Province of Ontario, the City of Mississauga, and the building industry all play important roles in making sure buildings are safe.

Provincial regulations

The Ontario Building Code (OBC), which is part of the Ontario Building Code Act, sets the requirements for any new construction in the city.

The OBC ensure that buildings are structurally sound, and that life safety measures, heating, ventilation and plumbing systems are in place when the building is constructed.

If you’re a building owner, you’re required to ensure that your building is maintained, repaired and evaluated in accordance with the Act and the OBC. You’re also required to keep documents, records and other information about the building in accordance with the Act and the OBC.

The role of the City

The City also has to make sure that buildings are designed and constructed in accordance with the provincial standards. We achieve this through our building permit and inspections process.

Residents and building safety

If you’re a resident of a building and you have concerns about safety, contact the building management group or condominium board.

If your concerns are not addressed, you can contact the City’s Compliance and Licensing staff at or by calling 311 (905-615-4311 outside city limits).

If you have questions about an active development in Mississauga, for example a site plan application, rezoning, or condominium registration, you can contact the City Planner responsible for the site.

For information regarding current building permits, residents can use our property information tool.

For urgent issues on weekends and overnight Monday to Friday, call After Hours Dispatch at 905-615-3000.

For any issues with Peel Living sites, contact the Region of Peel for more information.
