← Electrical Advice & Planning
A laneway home’s electrical supply should be planned with the electrical contractor and local utility before construction details are fixed. Whether an arrangement can use the property’s existing supply, needs an upgrade or can accommodate separate utility metering depends on the site and the utility’s review.
For Toronto homeowners, the first step is to define the home’s expected electrical loads and how you want electricity use to be billed. Those are related decisions, but they are not interchangeable.
Distinguish supply, distribution and metering
The utility service brings electricity to the property. Distribution equipment and feeders carry it to the intended loads. Metering records consumption under the approved arrangement.
A separate meter does not automatically mean a separate physical connection from the street or additional capacity. Similarly, installing a panel inside the laneway home does not establish that the main property’s service can supply it.
Prepare a complete load picture
Provide the proposed heating and cooling equipment, water heater, cooking appliances, laundry equipment and any EV charging plans. Include changes planned for the main house.
The contractor should assess the combined demands relevant to the proposed supply. Avoid assuming that floor area or the number of spare breakers gives a complete answer.
Confirm appliance choices early enough to inform the design. Switching from one heating or hot-water system to another after rough-in can affect the electrical plan.
Ask the utility about the actual property
Toronto Hydro provides service-connection and metering request processes. Use the applicable process to establish what is available for the property; do not treat a neighbour’s project as approval for yours.
Discuss the existing service, proposed additional dwelling, meter arrangement and any required changes. Utility review may affect equipment locations, design, costs and scheduling.
Keep assumptions clearly identified in early estimates. A contractor’s preliminary concept should not be mistaken for an approved utility connection arrangement.
| Question | Who should help resolve it? |
|---|---|
| Can the proposed loads be supplied? | Electrical contractor and utility, within their respective scopes. |
| What metering arrangement is available? | The serving utility. |
| Where can the feeder and equipment go? | Electrical contractor, designer and utility as applicable. |
| Who pays for electricity? | Owner, with appropriate billing and tenancy advice. |
Plan routes and equipment access
A rear-yard dwelling can involve a long or constrained route from existing equipment. Coordinate excavation with foundations, drainage, landscaping and other underground services.
Review panel and meter locations before layouts are finalized. Equipment needs suitable access for operation, inspection and future servicing. Include access arrangements for both dwellings in the design discussion.
If the project requires temporary construction power, address it separately from the permanent installation.
Compare proposals using the same assumptions
Ask proposals to identify included electrical work, utility charges or allowances, excavation, restoration and inspection coordination. Include any work required inside the main house.
Document who submits utility information and who follows up on approvals and scheduling. The construction programme should account for the connection process instead of assuming power will be available immediately after interior work finishes.
Common questions
Does a separate address guarantee a separate service?
No. Confirm the electrical connection and metering arrangement directly with the utility.
Can I settle the billing arrangement after construction?
Discuss your preference early. Changing the metering concept later may require equipment or design changes.
