Requirements Overview
The most critical requirement for operating a plumbing, heating, and air-conditioning contracting business in Charlottetown is the Business Licence. This is a legal prerequisite to run any business in the city, and you cannot legally operate without it. The licence shows you’re following local rules, and you’ll likely need to renew it annually or as required. Treat this as non-negotiable and get it in place before taking on work.
Once you’re licensed, focus on practical operations. This means meeting health and safety standards, maintaining a safe workplace, and securing any job-specific permits before starting work. For plumbing and HVAC projects, always follow code requirements and manufacturer guidelines, and ensure your team is trained to prevent injuries and protect customers’ homes.
Next, handle business registration and taxes. You’ll need a Business Number (BN) from the CRA to open a business account and file taxes. GST/HST registration may be required if your annual taxable supplies exceed the threshold. If you hire employees, you’ll also need Payroll Deductions registration and to set up proper payroll remittance. Keep these numbers current and file on time to avoid penalties.
Next steps: confirm the Charlottetown licence, set up your CRA BN, check GST/HST thresholds, and plan payroll registrations. Use a simple checklist and timelines, and don’t hesitate to reach out to local business services for help. You’re on the path to running a compliant, successful trades business.
