Vegetation Management

Improving reliability through our annual work program

With more than 150,000 circuit-kilometres of power lines across the province, line maintenance is one of our top priorities. From our planners to our trained arborists, technicians, mechanical operators, and herbicide applicators, our Forestry team plays an important role managing one of the leading causes of service interruptions — vegetation.

We are the only utility in North America with a dedicated, in-house vegetation management team. Maintenance of our assets includes managing vegetation on our right-of-ways, which is an integral component of providing Ontario with a reliable supply of the electricity we all depend on.
