Local Project Support

Coordinated retrofits and consultant support in Oakville.

Oakville projects range from commercial and institutional properties to employment-area buildings, mixed-use development and established multi-residential sites. Renovations may combine envelope, heat-pump, service, lighting and ventilation changes that need one coordinated design basis.

Where a building permit is required, the Town of Oakville administers the municipal review. Electrical service connections or upgrades may involve Oakville Hydro; the project address and current connection requirements should be confirmed before the design basis is finalized.

Architects can review our MEP consultant workflow for design teams; HVAC and plumbing scopes can use the mechanical permit-drawing guide.

The Conditions of Service require the metering provision and arrangement for service mains above 200 A or 800 V to be submitted to Oakville Hydro for approval before building construction begins.

  • The proposed service entrance rating (amperes), voltage and metering requirements, the total load in kVA and/or kW for winter and summer, and details of heating, air-conditioning, motor starting and other large loads
  • A survey plan and electrical site plan to scale showing the service entrance and meter locations and outside access to the meters, a schematic of the main secondary distribution system, and a scaled plan of the electrical room with metering provisions
  • For general service customers between 50 kW and 2,500 kW: three copies of the service entrance switchgear drawings, including any interlocking arrangements, for Oakville Hydro's approval
  • Connection authorization from the Electrical Safety Authority, which Oakville Hydro requires before it energizes the service
