Housing and Building Standards Ontario 3 Minutes Read · published February 11, 2026 Flag of Ontario

In Mississauga, Ontario, property owners must manage lead paint risks in older buildings to protect tenants, workers and visitors. This guide explains the typical testing and abatement steps, who enforces standards, how to report hazards and where to find official forms and help. Follow the practical action steps below to confirm whether lead paint is present, hire qualified testers and abate hazards safely while meeting municipal and public health expectations.

Hire certified testers for accurate results and documented reports.

Overview

Lead-based paint is more likely in properties built before 1978. Owners should prioritise testing before renovation, tenant turnover or when children or pregnant people live in the unit. Testing and abatement involve inspection, sampling, risk assessment, and either removal, stabilization or containment by qualified personnel.

Steps for Owners

  1. Arrange a professional lead risk assessment or paint testing by a certified inspector or risk assessor.
  2. Obtain a written report that identifies leaded surfaces, hazard locations, and recommended abatement methods.
  3. Notify tenants in writing if testing or abatement will affect occupied areas and provide timelines for work.
  4. Hire licensed or trained abatement contractors for removal, encapsulation or enclosure when required by health or building authorities.
  5. Retain clearance documentation showing re-inspection and safe re-occupancy criteria have been met.
Containment prevents dust spread during abatement work.

Penalties & Enforcement

Responsibility for lead hazards in residential buildings typically involves municipal enforcement for property standards and public health follow-up for exposure risks.

  • Escalation: first, repeat and continuing offences details are not specified on the cited page.
  • Non-monetary sanctions: orders to remedy, stop-work orders, property standards orders and court prosecutions may be used; exact remedies and processes depend on the enforcing office and are not fully itemised on the cited pages.

If you receive an order, act quickly and document remediation steps.
