Markham Construction Dust & Emission Bylaws
In Markham, Ontario, contractors must control construction dust and onsite emissions to protect public health and property. This guide explains which municipal departments handle dust and emission issues, typical control measures, permitting and inspection pathways, and how enforcement works in Markham. It is written for contractors, site supervisors, and residents who need clear action steps for compliance, reporting, and appeals.
Scope & What Contractors Must Do
Contractors should implement standard dust and emission controls at all stages of construction: covering soil, using water or suppression, installing silt fences and windbreaks, maintaining vehicles and equipment, and minimizing exposed areas. Where work affects public roads or sidewalks, additional controls and notifications may be required.
- Plan and document dust mitigation in site plans and daily logs.
- Use water trucks, misting systems, or stabilizers on exposed soil.
- Install erosion and sediment controls such as silt fences and sediment traps.
- Maintain equipment to reduce visible exhaust and fugitive emissions.
Permits, Notifications & On-site Plans
Some projects require building permits, site alteration permits, or specific erosion and sediment control plans submitted with permit applications; check the Building Division for application requirements and documentation.Building permits[1]
Applications & Forms
Permit names and forms vary by project type: for building permits, use the Building Division online applications; for site work affecting grading or public right-of-way, a site alteration plan or municipal site plan approval may be required. Specific dust-control forms are not always published as standalone forms on the cited pages.
Penalties & Enforcement
Enforcement of dust and emission controls is typically handled by the City of Markham By-law Enforcement and the Building Division, which respond to complaints and perform inspections. The city may issue orders to stop work, require remedial actions, or pursue fines where bylaws are contravened.By-law Enforcement[2]

- By-law Enforcement and the Building Division handle inspections and enforcement; environmental health matters may involve regional or provincial authorities in specific cases.
- What evidence helps if I am issued an order?
- Daily logs, dated photos, maintenance records, and permit documents help demonstrate compliance or reasonable efforts to mitigate dust.
