Electrical panel work is safety-critical. Do not open panels, replace breakers, modify wiring, or bypass permits yourself. This page is educational and is not a substitute for a licensed electrician or the local authority having jurisdiction.
Quick Answer
What homeowners need to know first
A secondary suite can add cooking, laundry, water heating, heating, cooling, and vehicle-charging demand. The project may use existing panel capacity, a sub-panel, a larger panel, or a service upgrade. Separate metering is a different decision and depends on ownership, utility, and local rules. Start with the complete suite design and a load calculation.

Details
Practical Canada homeowner details
A sub-panel adds distribution space but does not increase total service capacity.
Suite heating and water-heating choices can drive more demand than lighting and receptacles.
Separate metering can require utility design, additional service equipment, and municipal approval.
Fire separations, building permits, development rules, and electrical permits are separate approval streams.
Future EV charging for the main home or suite should be included before finalizing service size.

FAQs
Electrical Panel Planning for a Secondary Suite in Canada FAQs
Does a basement suite always need a separate electrical panel?+
No. The design depends on available circuit space, service capacity, suite loads, local requirements, access, and how the owner wants circuits organized. A sub-panel is common but not universal.
Does a secondary suite require 200 amp service?+
Not automatically. A load calculation should include the main dwelling and suite equipment. Heating, hot water, cooking, laundry, and EV charging choices strongly affect the result.
Is separate electrical metering required for a suite?+
Requirements and options vary by municipality, utility, property type, and ownership model. Separate billing goals should be discussed before the electrical design is finalized.
