Installing a home EV charger: permits, spare capacity and who may do the work

Many EV owners treat the charger like an appliance: buy it online, find someone to hang it on the garage wall, plug in. The charger itself is the easy part. The circuit behind it is permanent electrical work, and the mistakes that cost money are a missing permit, a panel that cannot carry the load, and equipment that is not certified for Canada.

It is electrical work, so it needs a permit

The Electrical Safety Authority's homeowner sheet on EV charging says a notification of work must be filed with ESA before the installation starts, and that the person doing the installation must file it. Installations must meet the Ontario Electrical Safety Code, in particular Section 86, Electric Vehicle Charging Systems. BC Hydro's guide for single-family homes says an electrical permit must be in place before installation starts. If an electrician does the work, the electrician applies; if you do it yourself, you apply to your municipality or through Technical Safety BC. A charger put in without a permit can surface later, when an insurer, a buyer's inspector or a rebate program asks for the paperwork.

Who may do the work

ESA states that in Ontario, if you hire someone to do electrical work in your home, by law it must be a Licensed Electrical Contractor, and that a local distribution company or its affiliate doing the installation must also hold an ECRA/ESA electrical contracting licence. Licensed contractors can be looked up at findacontractor.esasafe.com. BC Hydro recommends hiring an electrician for both the capacity check and the installation, and points to an EV electrician referral through the Alliance of Energy Professionals. A handyman with a charger in the truck is not the same thing.

Check spare capacity before you buy

ESA warns that you may need an electrical service upgrade to accommodate the charging system and that the charger should be on a dedicated circuit. BC Hydro suggests the electrician review the past 12 months of your meter data to see how much spare capacity the house really has. Based on that, the electrician may recommend an EV power management device so the charger shares the existing service instead of forcing an upgrade. If power management is not enough, a service upgrade involves the utility, which takes time, so this check belongs before you order the car, not after it arrives.

Certified equipment and outdoor use

ESA says an EV charging system must carry the official mark or label of a recognized certification or evaluation agency, and that electrical products must be approved before they are used, sold or advertised in Ontario. The list of recognized marks is at esasafe.com/approvalmarks. A charger mounted outside must be rated for outdoor use, and ESA advises keeping the cable off the floor to avoid tripping and wear. Cheap imported units without a recognized mark are a common reason an inspection fails.

Keep the paperwork

In Ontario, ESA issues a Certificate of Acceptance once the installation meets the code; ask the contractor for a copy. In BC, a homeowner who does the work must submit declarations and request the inspection within the permit's time limits. BC Hydro's rebate for single-family homes, row homes and duplexes requires an eligible charger from its list; check the current amount and conditions on the BC Hydro page before you buy, because programs change.

Prevention Checklist

• Ask for a load check, ideally from 12 months of meter data, before choosing a charger.
• Hire a licensed electrical contractor (Ontario) or an electrician (BC) and confirm who files the permit.
• Buy a charger with a recognized Canadian certification mark, rated for outdoor use if it goes outside.
• Ask whether a power management device avoids a service upgrade.
• Keep the Certificate of Acceptance or the inspection record with your house papers.
• Check rebate rules before buying; some require an approved model and a permit.
