Open Burning Smoke Control Regulation

The Open Burning Smoke Control Regulation (OBSCR) outlines open burning rules.

These rules ensure burning is done with minimal risk to human and environmental health and minimizes smoke from open burning, especially where people live.

Before you burn

Before burning, you must explore every reasonable alternative, including:

• Chipping
• Mulching
• Transporting your material to a green-waste recycling facility

You also need to minimize the amount of material to be burnt.

Under the Waste Discharge Regulation, there's a list of prohibited materials that cannot be burned in an open fire. Exclude these materials from your open fire.

Consult the Prohibited Materials Burning Factsheet (PDF, 103KB), or review Schedule 1 under the Waste Discharge Regulation.

Find your smoke sensitivity zone

The province is broken into 3 smoke sensitivity zones:

• High
• Medium
• Low

The open burning rules are based on these zones.
