Step-by-step verification

  • Ask whether you are hiring an individual electrician, an electrical contractor business, or both.
  • Search the individual's name or certificate details in the Skilled Trades Ontario Public Register.
  • Check electrical contractor guidance through the Electrical Safety Authority.
  • Compare the legal business name, phone, address, and authorization details with the quote.
  • Ask whether the work requires permits, notifications, or inspections.
  • Keep the official lookup result with the written estimate and invoice.

What can differ

  • An electrician and an electrical contractor business are not always the same record.
  • Ontario trade records and municipal permit records can answer different questions.
  • A valid record does not guarantee workmanship or current insurance.
