Ontario is strengthening the regulation of vertical closed-loop drilling for geothermal energy systems, with new rules that take effect immediately.

The province’s goal is to improve public health and safety by requiring geothermal installers to:

  • obtain provincial approval for vertical closed-loop geothermal systems,

  • consult with a certified geoscientist or engineer before drilling, and

  • develop an emergency plan before drilling.

The Ministry of the Environment will consult with industry stakeholders in the coming months on the new regulations. The ministry also will be conducting inspections to ensure installers are meeting safety standards.

Increasing green energy, such as geothermal systems, is a part of the government’s plan to grow renewable energy and shut down dirty coal plants to ensure a strong, green economy for future generations.
