Clearances
Electrical clearances help keep the public and workers safe. They also prevent power outages and allow space for us to operate, maintain and replace the electrical distribution infrastructure. Always confirm clearance requirements before starting construction.
Severances, minor variances or permits
If your project requires municipal approval (severance, minor variance or building permit), check where our electrical infrastructure is located before seeking city approvals.
Electrical servicing
Request a new electrical connection or an upgrade to an existing service by filling out and submitting the Electrical Service Request Form.
Commercial design specifications
We offer standard construction drawings and design specifications free of charge to developers, contractors and consultants. They can help streamline the design and construction process.
