Air Emission Permits in London, Ontario - How to Apply

Environmental Protection Ontario 3 Minutes Read · published February 12, 2026 Flag of Ontario

In London, Ontario industrial air emissions are regulated through provincial approvals and local bylaws. Depending on the source and scale of emissions, businesses usually need an Environmental Compliance Approval (ECA) from the Government of Ontario and must comply with City of London nuisance and air-quality bylaws. Early coordination with the provincial regulator and the City helps avoid delays and enforcement risk.[1] For local complaints or bylaws that affect permits, contact City of London municipal staff.[2]

Overview of Permitting Requirements

Most industrial air emissions are controlled under Ontario statutes and require an approval or registration. The City enforces local nuisance and air-quality rules and may require municipal permits or approvals for related activities such as open burning, demolition, or construction that generate dust or smoke.

Start by identifying all emission sources at your facility and gather process data.

Penalties & Enforcement

Enforcement may be undertaken by the provincial regulator for approvals (e.g., Environmental Compliance Approvals) and by City of London by-law officers for local breaches. Specific monetary penalties, escalation steps and time limits for appeals are set in the controlling provincial or municipal instruments.

  • Monetary fines: specific amounts are not specified on the cited pages; consult the controlling approval or bylaw for precise figures.
  • Escalation: first, repeat and continuing offences procedures are governed by the applicable provincial approval or municipal bylaw; amounts and ranges are not specified on the cited pages.
  • Non-monetary sanctions: orders to stop operations, directives to remediate, suspension or revocation of approvals, and seizure of equipment or court action may be used.
  • Enforcers: Ministry of the Environment, Conservation and Parks for provincial approvals; City of London By-law Enforcement for municipal matters.
  • Appeals/review: appeal routes depend on the instrument; specific time limits are not specified on the cited pages and should be confirmed on the approval or bylaw text.
If you receive an order, act immediately and seek the specific instrument to confirm deadlines for compliance or appeal.

Applications & Forms

Provincial air approvals (commonly called Environmental Compliance Approvals or equivalent) use Ontario application forms and submission procedures; the exact form name/number and fees are set by the provincial process and by the specific approval type and are not specified on the cited page. Municipal applications for related permits (burn permits, construction permits) are available from City of London where published.[1][2]

How to Prepare an Application

  1. Inventory emission sources and quantify rates, controls, and operating hours.
  2. Engage a qualified air-quality consultant to compile required technical reports and dispersion modelling where necessary.
