The Open Burning Smoke Control Regulation (OBSCR) was first enacted in 1993. Following an extensive development process and wide consultations, a new OBSCR came into effect on September 15, 2019, and replaced the old regulation.
The OBSCR governs the burning of vegetative material associated with a range of activities, such as land clearing, forestry operations and agriculture. It sets out the conditions under which open burning of vegetative debris can be authorized. The revised regulation mainly supports the objectives of reducing impacts on human health, enabling and encouraging compliance, and minimizing undue costs to industry.
The regulation does not generally prohibit burning but rather aims to ensure that open burning is conducted with minimal risk to air quality. While facilitating some necessary open burning practices, the new regulation also maintains air protection measures and alternatives to burning are strongly encouraged.
