No provincial sales tax: 5% GST is all you charge
Alberta is the only province with no provincial sales tax. If you sell taxable goods or services, the 5% federal GST is the only tax on your invoices. No PST registration, no provincial return to file. Once you cross the $30,000 small-supplier threshold, you register with the CRA and remit GST like everyone else, but the bookkeeping stays simpler than in any other province.

Using a business name? File a Declaration of Trade Name
If you operate under any name other than your own exact personal name, you must file a Declaration of Trade Name with the Alberta Corporate Registry through an authorized service provider (the local registry agent offices). The filing costs $40 to $60 depending on the agent. It puts your business name on the public record so customers can find out who is behind it. Registration does not give you exclusive rights to the name the way a trademark would.

Hire your first worker? You have 15 days to open a WCB account
If your industry is one where workers' compensation coverage is mandatory, you must open a WCB-Alberta account within 15 days of hiring your first worker. Full-time, part-time, casual, and contract workers all count. Sort this out the week the hire starts, not after an incident. Sole proprietors without employees are not required to carry coverage, but can buy personal coverage from WCB voluntarily.

Some trades are compulsory certification trades, electrician included
Alberta designates certain trades as compulsory certification, meaning only registered apprentices, certified journeypersons, or holders of a recognized trade certificate may perform the restricted work. Electrician is one of the strictest: the apprenticeship runs 72 months with 9,180 hours of on-the-job training plus theory exams, and the AIT application costs $150. Experienced workers without an apprenticeship can challenge the exams through the Trades Qualifier Program instead.
