How many services can I have to my property?
For both primary and secondary services, Hydro Ottawa will designate one supply point with a single supply voltage per property. This could be an underground cable chamber, pole, or pad-mounted device. This supply point could also be located on an adjacent property for which Hydro Ottawa has land rights. Where Hydro Ottawa owns and controls the on-property outdoor primary distribution system, Hydro Ottawa may, at its discretion, provide multiple supply points to the property. Where a property is electrically connected to an adjacent property by powerlines, Hydro Ottawa will not provide another supply point for the adjacent property unless the initial electrical connection is removed. In all cases the final supply point is the sole and exclusive decision of Hydro Ottawa.

What is Hydro Ottawa’s property reinstatement policy when working in the road allowance or on Hydro Ottawa easements?
If any repair of the powerlines on your property is required, Hydro Ottawa will reinstate outdoor surfaces with sand, gravel, and/or soil. It is your responsibility to repair/replace vegetation (e.g., shrubs, trees, lawn, gardens), hard surfaces, structures (e.g., decks, fences, patios, sheds, pools, play structures), foundations and buried, shallow utility services such as telephone, cablevision or watering systems disrupted by the repair.
Conditions of Service Section 3.0.8
How close can I build to an overhead powerline?
The construction of permanent structures within the “restricted zone” surrounding overhead powerlines is prohibited. This zone is defined by Hydro Ottawa’s clearance standard (see OLS0002). The “restricted zone” consists of a five metre (16 feet) radial distance from overhead medium voltage powerlines, and a two-metre (6.5 feet) distance from a vertical line drawn from the powerlines to ground level along the length of the pole line. This standard complies with the requirements of the Ministry of Labour’s Occupational Health and Safety Act and the Ontario Electrical Safety Code. These requirements prohibit any work activity within 3 meters (10 feet) plus conductor swing (the side-to-side, up-down conductor movement) of primary voltage powerlines with a final clearance of five metres for construction and future maintenance of the building.

What is the difference between a residential & commercial service?
Residential services are typically a 120/240V, 1-phase, 3-wire, up to a maximum of 400A, where available and may be subject to additional restrictions. For residential services requiring a larger supply than previously mentioned and for 3-phase services you should refer to our Conditions of Service.
Commercial services (or General Services) include small apartment buildings, dense condominium arrangements, small commercial buildings, agricultural properties, billboards, and industrial and institutional developments supplied from the public road allowance or a Hydro Ottawa easement.
Conditions of Service Section 3.2 (General Services, secondary voltage supply) and
Section 3.3 (General Services, primary voltage supply).
What is the difference between a residential subdivision and a residential infill?
“Infill Service” means any service, rural or urban, which was not part of a pre-planned subdivision or a service that was installed five years or more after the pre-planned subdivision had the primary electrical installation “substantially completed.”
“Residential Underground Subdivision” means a residential area with three or more homes supplied from an on-grade pad-mounted transformer(s), transformer sidewalk vault, or secondary pedestal(s) by underground secondary cables.

Will I be required to pay a security deposit? If so, can it be waived?
As a condition for supplying or continuing to supply electrical distribution services, Hydro Ottawa will request security deposits from customers, based on the customer classification and the customer’s billing history. Security deposits are established and managed in accordance with Sections 126.96.36.199 to 2.4.29 of the Distribution System Code (DSC).
Conditions of Service Section 2.4.3
Non-residential customers opening an account may qualify for a deposit waiver based on criteria outlined in

Can the pole line on my street be buried underground?
Hydro Ottawa’s standard construction for its electrical distribution system on/or crossing municipal arterials, major collectors, highways, rivers, railways, open fields, rural areas, flood plains and business parks, excluding greenfield residential, is overhead distribution.
All costs associated with the relocation, or conversion from overhead to underground are the responsibility of the requestor unless an existing agreement is in place. If the relocation of Hydro Ottawa’s distribution system is on lands not owned by the requestor, it is the responsibility of the requestor to complete negotiations with the landowner to the satisfaction of, and at no cost to Hydro Ottawa.
