Requirements Overview
The most critical requirement for operating a plumbing, heating, and air-conditioning contracting business in Lethbridge is the Plumber Journeyperson Certificate. This license is legally required to supervise and perform plumbing work, and you cannot operate the business without it. This is non-negotiable. If you also plan to do gas work, the Gasfitter Journeyperson Certificate is another essential credential you’ll need to have or hire someone who holds it for gas-related projects.
Beyond licenses, there are essential operational steps to keep people safe and compliant. Make sure you’re registered with Alberta WCB (Employer Registration) so workers are covered, and use the Alberta Apprenticeship and Industry Training system (Tradesecrets) to arrange approved training for apprentices and staff. You’ll also need a valid Business Licence to operate in your city, and if you intend to use a trade name, register it with Alberta Business Name Registration (Trade Name/Sole Proprietorship). These steps help you stay compliant with day-to-day operations and training requirements.
For the business side, you’ll need key registrations and tax numbers. Expect to obtain a Business Number (BN) from the federal government for taxes and filings, and decide your structure: Alberta Corporation Registration if you form a corporation, or Partnership Registration if you form a partnership. If your turnover meets the threshold, register for GST/HST and set up Payroll Deductions for any employees. With these basics in place, you’ll be ready to handle invoices, payroll, and taxes smoothly.
Next steps: start with securing the critical licenses, then set up the required registrations and training plans. Reach out to a local business advisor or accountant, build a simple checklist, and tackle each milestone one by one. With a clear path and the right registrations, you’ll be confidently ready to serve customers in Lethbridge.
